Fixes#8365.
Fixes#9716 - at least the specific issue reported. My Android Studio
still complains about Gradle versions - it ships with v3.2, but requires
v3.3...
Add a 'generate dependencies' task to the Gradle build, which checks if
the snapshot dependencies file exists, and runs an extra build before
the actual FlutterTask if it doesn't. This makes the first build slower,
but sub-sequent builds (without source changes) much faster.
Fixes#9717.
FlutterCommand.runCommand subclasses can optionally return a FlutterCommandResult which is used to append additional analytics.
Fix flutter run timing report and add a bunch of dimensional data
If the user specified a non-exact device id, it was producing
an exception whereby we were trying to listen to the
`getAllConnectedDevies()` stream twice.
`adb` can sometimes hang, which will in turn hang the Dart isolate if
we're using `Process.runSync()`. This changes many of the `Device` methods
to return `Future<T>` in order to allow them to use the async process
methods. A future change will add timeouts to the associated calls so
that we can properly alert the user to the hung `adb` process.
This is work towards #7102, #9567
There is a race where we could complete a future based on a stream event
and then before we cancel the stream subscription, we get another event
and try and complete the future again.

This package now depends on collection and quiver. The package level
dependencies in the BUILD.gn file should match the list of dependencies
in the pubspec.yaml file for the Fuchsia build to function.
Uninstalling the app removes the data and cache directories, so this
allows application data to persist across multiple flutter run
invocations.
This also handles the edge case where the app fails to install due to an
error in installation (e.g. debug keystore changes, switching from a
release keystore to a debug keystore, etc.).
Gradle projects are evaluated in lexicographical order, and the plugin
projects are at the same level as the :app project, so if a plugin has
a name that comes before 'app' (like, for example, any name that starts
with a capital letter), the plugin project will be evaluated before
:app.
Since :app applies the Flutter Gradle plugin, which tries to
modify the dependencies of the plugin projects, we have a problem if the
plugin projects have already been evaluated. Adding
evaluationDependsOn(':app') to the plugin projects fixes this.
Updated example projects to the latest (plugin-enabled) Gradle build
files.
Also removed two unused imports in `pluginClass.java.tmpl`.
Xcode builds depend on the Python 'six' module. If not present, exit
immediately with a useful error message.
The six module is included in the system default Python installation. We
perform this check in case a custom Python install has higher priority
on $PATH; e.g., due to a Homebrew or MacPorts installation.
This extracts an existing doctor check to use it during the build step
as well.
Plugin projects are created by running `flutter create --plugin <name>`.
An example app is also created in the plugin project, using the normal 'create' template, which has been modified to allow for conditional plugin code.
Modified the android package name to match package naming conventions (all lower-case, and must match the directory name).

The very first time `pod install` is invoked, CocoaPods downloads the master spec repository, which takes quite a while. Before this change, the build appeared to have stalled. With this change, at least the spinner is moving.
Added `pod setup` to the install instructions for CocoaPods, so the spec repo is downloaded while setting up Flutter, instead of during the first build.
Old Android Stuio versions pior to 2.2.0 didn't come with Java bundled. Make sure flutter doesn't crash when we try to determine the Java version of those old Android Studio installations.
Go through all packages brought in by pub, and write the name and path of every one that is a flutter plugin into .flutter-plugins.
In android/settings.gradle and ios/Podfile, read in .flutter-plugins, if that file exists. The Android / iOS code from the plugins is automatically added as dependencies of the native code of the app.
**THIS IS A BREAKING CHANGE.** See below for migration steps for
existing projects.
Previously, Flutter app code was built as a raw dylib on iOS. Dynamic
libraries outside of a framework bundle are not supported on iOS, except
for the system Swift libraries provided by Xcode.

* Migrates Xcode build from app.dylib to App.framework
* Migrates flutter create template
* Migrates example projects
Migration steps for existing projects
=====================================
The following steps should be taken from the root of your Flutter
project:
1. Edit `ios/.gitignore`: add `/Flutter/App.framework` on a new line.
2. In the Xcode project navigator, remove `app.dylib` from the Flutter
folder. Delete this file from the `ios/Flutter` directory in your project.
3. Run a build to generate `ios/Flutter/App.framework`. From the command
line, run `flutter build ios`. If you have not configured app signing
in Xcode, an alternative method is to open the simulator, then run
`flutter run -d iP`.
4. In the Xcode project navigator, select the `Runner` project. In the
project settings that are displayed in the main view, ensure that the
`Runner` target is selected. You can verify this by exposing the
sidebar using the [| ] icon in the upper-left corner of the main
view.
5. Select the *General* tab in the project settings. Under the
*Embedded Binaries* section, click '+' to add `App.framework`. In the
sheet that drops down, click the *Add Other...* button. Navigate to
the `ios/Flutter` directory and select `App.framework`. Click *Open*.
In the sheet that drops down, select *Create folder references*, then
click *Finish*.
6. In the project settings, verify that `App.framework` has been added to the
*Embedded Binaries* and *Linked Frameworks and Libraries* lists.
7. In the Xcode project navigator, drag `App.framework` under the
Flutter folder.
8. In the Xcode project navigator, select `Flutter` then from the
*File* menu, select *Add Files to "Runner"...*. Navigate to the
`ios/Flutter` directory, select `AppFrameworkInfo.plist` and click
the *Add* button.
9. From the command line, in your project directory, run
`flutter build clean`, then `flutter run`.
At this point your project should be fully migrated.

The old `whichAll` implementation was not considering different extensions for executables on Windows. By defering to OS-built-in tools we avoid implementing it.
Fixes#8882.
* Update gradle wrapper and build-tools version.
Tested manually by "flutter create" with Idea "flutter run" and from android studio "run" android app.
* Update com.android.tools.build to 2.3.0
* Remove legacy .apk build.
Print out an error message telling the user to upgrade the project if
it's not Gradle-based. Removed all the obvious traces of the legacy
build.
Added support for Dart VM kernel snapshots in Gradle builds.
Fixed Android installs to verify that the app is actually installed, and
not just rely on the presence of the .sha1 file.
The problem has been fixed upstream in the Dart VM.
This simplifies our setup instructions on Windows (will update the wiki).
Furthermore, this also means that going forward there is no diffrence between PowerShell and Cmd for the Flutter experience on Windows.
Function keys don't work great on any platform we support:
* Mac doesn't have first-class function keys.
* On Ubuntu: F1 opens the system help and F10 opens the file dialog.
* ... and Windows is a mess as well.
* Only run pod install if CocoaPods v1.0.0 or greater is installed.
Avoid issues with older versions of CocoaPods breaking the build. Users who genuinely use older versions of CocoaPods will have to run pod install manually when required.
* Make ProcessSignals portable
This removes the need to wrap unsupported signals with in `if (!platform.isWindows) ..`.
It also allows us to implement a work around for breaking the Windows console when flutter is exited with Ctrl+C.
* review comments
* adding tests
* add license header
Changed the default build output directory in the new project template
to build/, instead of android/build/ and android/app/build/.
Updated tools to ask the Gradle scripts what the build directory is,
since this is configurable in the build scripts, and we need to know
where the build output actually is.
Silenced output from 'flutter build aot' when invoked from Gradle, since
the output was confusing in this case.
Fixes#8723Fixes#8656Fixes#8138
1. Add `PortScanner` abstraction so that we don't do actual port scanning
in tests.
2. Don't change the real `cwd` of the isolate during tests, as it affects
all tests, not just the current running test.
Fixes#8761
- [x] Add custom logic on MacOS to determine if Java is installed before invoking `java`.
- [x] Check JAVA_HOME, platform specific logic, and finally PATH to locate the `java` executable.
- [x] Improved doctor messages.
Fixes#8508Fixes#8521
* Use snapshot's .d file as source inputs in Gradle build.
If we don't yet have a .d file (first build), fall back to using the
.dart files in the current directory. This enables us to detect changes
in dependent source files (Flutter framework, packages outside the
source directory, etc.), and re-generate the snapshots as needed.
Unfortunately, Gradle requires knowing the source files before executing
the task, and can't update them after building, so Gradle considers the
second build to be out-of-date (because it has more input files than the
first build). Sub-sequent builds have the correct dependency
information, and will be skipped if the source files haven't changed.
Also added a dependency on gen_snapshot. The snapshot ABI isn't stable,
so we need to re-generate the snapshots when we roll the Dart SDK
dependency.
Fixes#8315Fixes#8687Fixes#8607
It was resulting in weird situations where the tool would dump an
error message and stack but not quit, or would fail hard but then just
hang.
Instead, specifically catch errors you expect. As an example of this,
there's one error we expect from the DartDependencySetBuilder, so we
catch that one, turn it into a dedicated exception class, then in the
caller catch that specific exception.
* Revert "Eliminate CocoaPods install step (#8694)"
This reverts commit f4a13bc72b.
If the developer is relying on CocoaPods and hasn't done a pod install, we will do it for them. This is needed for a smooth native plugin experience, similar to what Gradle is doing on the Android side.
There's no hard dependency on CocoaPods. We only run pod install if the project uses CocoaPods, so developers are still free to use alternatives if they prefer (and if they don't want to use native plugins).
Fixes#8685Fixes#8657Fixes#8526
* Require CocoaPods 1.0.0 or newer.
And make sure we don't get a crash if running `pod install` fails.
* Address review feedback
If the developer is relying on CocoaPods and hasn't done a pod install,
they'll get a build failure indicating the issue.
This also avoids a hard dependency on CocoaPods in the tool and allows
developers to customize their Xcode steps to use alternatives such as
Carthage if they prefer.
As of the latest Xcode versions, the latest published libimobiledevice
is out-of-date and build from HEAD is required.
This fixes two bugs:
1. Update initial install instructions to add --HEAD flag.
2. Update uninstall, reinstall instructions to include
--ignore-dependencies flag, since other brew formulae depend on
libimobiledevice.
Since iOS builds are CocoaPods enabled by default, we should make sure to run `pod install` to get pods wired up before building the app.
Also added a check to `flutter doctor` to verify CocoaPods is installed.
I'm passing FLUTTER_FRAMEWORK_DIR to the `pod install` command, so we can have the app's Podfile link in Flutter.framework as a pod instead of having to copy it over in xcode_backend.sh.
This implements the `DartDependencySetBuilder` completely in Dart instead of calling out to `sky_snapshot` (Linux/Mac) or `gen_snapshot` (Windows) and allows us to use the same code path on all supported host platforms.
It also slightly reduces hot reload times on Linux from ~750ms to ~690ms for the unchanged flutter_gallery app and significantly reduces hot reload times on Windows from almost 1.5s to just slightly slower than on Linux.
This change will also allow us to retire `sky_snapshot` completely in the future.
1. Add matchers for the `ProcessExit` exception class
2. Add ability to control the setup of the `AppContext` we use in
`testUsingContext()`
3. Clean up the code that figures out the location of `Cache.flutterRoot`
such that it works with `pub run test`. It previously only worked
when the tests were invoked with standalone `dart`
`#3` above will also help unblock #7941
* Small update to instructional comments in app template
* Update Flutter Driver comment
Good suggestion to add the link, Seth! I also updated the working to match what that page uses.
* add crash reporting without enabling it
* do not drop futures on the floor
* return exitCode from executable run
* debug travis
* remove unnecessary todo
* rename local fs getter
* Enable Hot Reload on Windows (backed by gen_snapshot)
\o/
Two caveats:
* Hot Reload on Windows is slower than on other platforms because gen_snapshot is slower then sky_snapshot
* We currently cannot hot reload projects with spaces in the path
* enable tests
The gradle build scripts can be configured to output different
application IDs for different build types, so we need to examine the
built .apk to figure out the name of the package and activity.
Re-landing this change, updated to only get information from the .apk
if it exists.
Since the tools create an AndroidApk instance early, even before we've
actually built an .apk, we have to create a new instance after building,
so we can start the right app/activity.
Fixes#8327.
* [devFS] Use URI to represent paths on device
Previosuly, regular file paths in the format of the host platform were used to represent paths on device. That works when host and device share the same (POSIX) file path format. With a Windows host, this breaks. URIs are the solution as they are platform independent and the VM service on the device already interpreted the file paths as URIs anyways.
* review comments
* switch to file paths
* fix tests on Windows
* review comments
* Revert "Revert "Simplify path handling logic in dependency checker and devFS (#8414)" (#8467)"
This reverts commit 96ba7f76d2.
* Intentionally use a self-package URI in flutter_gallery
* tests to catch problems with self-package imports
This adds support for a `--bug-report` flag, which is a recording
that:
- includes the arguments that were passed to the command runner
- is zipped up for easy attachment in Guthub issues
* Simplify path handling logic in dependency checker and devFS
Simplification will make it easier to port this to Windows.
* Roll Engine to 0a7b177c330367904597a6129b3eb653d29dfca0
The gradle build scripts can be configured to output different
application IDs for different build types, so we need to examine the
built .apk to figure out the name of the package and activity.

It's not just $HOME/.AndroidStudio2.2, it might also be
.AndroidStudioPreview2.3, or .AndroidStudioFooBar1.7, or whatever.
Made the Version parser less throw-happy, and relaxed the directory name
checks to allow for the above.
Fixes#8353.
* Bump to test `0.12.20`.
Some test `0.12.20` highlights:
* introduces `expectLater()` that returns a `Future` that completes when the matcher has finished running
* deprecates the `verbose` parameter to `expect()` and the `formatFailure()` (to be removed in `0.13.0`)
Otherwise:
* to keep up w/ the deprecation of `verbose`, removes `widget_tester` API to pass `verbose` flag (alternatively we could suppress the warning for now)
* Update stack manipulation.
* Fix framecount.
If a target file is specified on the flutter tools command line, pass it
through to Gradle.
It is still possible to statically specify a target file in the flutter
section of build.gradle, but it is now possible to specify it on the
command line as well. The command line option takes precedence.
Fixes#8175.
Only implemented for Android devices for now. Compare the installed SHA1
to the latest build. If they match, there's no reason to reinstall the
build.
Fixes#8295
* Fix bug parsing Gradle version.
Version from pub_semver requires versions of the format X.Y.Z. Gradle
doesn't follow semantic versioning, though, so version parsing would
fail on versions like '3.2'. Fixed by writing a custom Version class.
Also removed a check for apksigner when building Gradle-based projects.
Fixes#8298
Do not attempt to deploy/debug wifi connected iOS devices. ios-deploy is
able to install over wifi, but we've had several bugs reporting failure
to run/debug once installation has completed when the device is also
connected via USB. Note that we don't currently support deploy/debug
over wifi since libimobiledevice (which is also required) requires a USB
connection.
* Remove SHA1 check from AndroidDevice.isAppInstalled()
The docs for isAppInstalled say 'check if a version of the given app is
already installed', however the current code returns true only if it's
the latest build that's installed.
This made sense in the past, when the use pattern was:
if (!isAppInstalled(...)) installApp(...);
but now the usage is:
if (isAppInstalled(...)) uninstallApp(...);
installApp(...);
This has the probably unintended consequence that if you run `flutter
install` or `flutter run` two times in a row with no source changes, the
second invocation will uninstall the app, but the first invocation might
not.
Removing the SHA1 check makes us always uninstall the app if it's
installed.
Fixes#8172
* Teach flutter tools to find gradle
Flutter tools will now use Gradle from Android Studio, which is now found automatically.
flutter doctor will verify that Android Studio has been installed, and that the included Gradle is at least version 2.14.1.
It is still possible to manually configure the path to Android Studio (flutter config --android-studio-dir=XXX) or Gradle (flutter config --gradle-dir=XXX), but this should only be necessary if they're installed somewhere non-standard.
Only tested on Linux and macOS for now.
Fixes#8131
* Do not attempt to merge non-fat frameworks in Xcode build
During the Xcode build, we strip code irrelevant to the target
architecture in frameworks used by the application. In the case of
non-fat executables, no stripping occurs, so the frameworks can be used
as-is. No merge & replace step is necessary.
* fixup! Do not attempt to merge non-fat frameworks in Xcode build
Artifacts are now located in a central place.
This will enable us to downlaod artifacts when we need them (instead of
downloading them all upfront).
This also makes replacing sky_snapshot with gen_snapshot easier.
If a developer has installed the Xcode command-line tools, then later
installs Xcode, they may need to run xcode-select to update the path of
the command-line tools to that of the new installation.
The "old" APK build did not include Roboto fonts, but the new
Gradle-based build did. This is due to `flutter build flx` defaulting to
include the fonts, where the old `flutter build apk` defaulted to NOT
include them.
So let's change the Gradle build to also not include Roboto fonts.
Fixes#8149
On flutter run, we update ios/Flutter/Generated.xcconfig with various
Flutter-specific settings required by xcode_backend.sh during a build
from Xcode. These settings need to be present at the time the project is
loaded since Xcode doesn't pick up live updates to these files.
Without these settings, Xcode fails to locate xcode_backend.sh itself,
causing the build to fail until the Xcode project has been closed and
re-opened. This also prevents Xcode's project updater from 'helpfully'
suggesting to clean up and delete the Generated.xcconfig file.
* Make new project template gradle-based for Android.
With this change, the 'new project' template uses the same gradle-based build for Android as the hello_services example. This has some implications on build performance, since we're now building a complete Android app instead of just combining a pre-compiled .dex with the Flutter assets.
The very first build is a little over 2x slower, since it needs to download gradle and build the build scripts before getting to the actual code. Subsequent builds with changes to the code are comparable to the old builds. Null builds are faster. Enabling the gradle daemon speeds up subsequent builds by around 5s.
* Move Flutter Gradle plugin to Flutter root.
Required to handle Flutter SDK (and other) paths that include spaces.
Also includes general cleanup:
* Declare explicitly that we use /bin/bash, since we rely on its
features.
* Add -- where possible, to avoid interpreting files starting in - as
options.
* Suppress output of pushd/popd.
* Avoid stringifying arrays.
* Fix potential NPE in iOS doctor check
In case Xcode is not installed, the xcode-select path may be null.
* fixup! Fix potential NPE in iOS doctor check
If the developer has only installed the Xcode command-line tools,
xcode-select and some other tools may be present, but xcodebuild will be
missing. In this case, output a slightly improved message indicating
that the installation is incomplete rather than missing.
Support for thinning app frameworks to the target architecture was added
in 708909fc6b. This commit adds support
and error-checking for non-fat frameworks that are not of the target
architecture. In such cases, we now fail the build, and emit an error
message and the contents of lipo -info for the affected framework.
* Support thinning iOS frameworks to supported architectures
When building against frameworks that are distributed as
multi-architecture fat binaries, we want to strip the frameworks we
distribute down to only the architectures specified in $ARCHS.
This patch adds:
* The ability to specify commands to xcode_backend.sh (if none is
specified, run BuildApp for backward compatibility).
* A 'thin' command that invokes lipo to thin down the distributed as
described above.
* Add framework thinning step to iOS build
Invokes xcode_backend.sh thin on the build application.
* Limit architectures to arm64 in Xcode template
Flutter does not yet support armv7 iOS devices. Limit the $ARCHS build
variable to arm64 until then.
* Small Flutter strong mode cleanup fixes.
These are cases where strong mode down cast composite errors
generally indicated cases that would performance or correctness
issues if Flutter code was run in a strong mode VM.
* Fix Command API so that it is always in terms of Map<String,String>.
* Fix typedef
If ensureDirectoryExists fails -- e.g. because a file file of the same
name as the directory to be created exists, ensure that we exit cleanly
with a useful error message.
By default, pass status bar taps to the root view controller in
generated Flutter apps. Developers should customise as necesary if they
later create one or more alternate FlutterViewControllers that they'd
like to forward these to.
If the tool is started immediately after a previous run of the tool, then
the most recent log timestamp may come from the previous run's logs.
The new instance of the tool should not print those logs.
This was happening during runs of the microbenchmark script.
* Add doctor check for Python 'six' module
Required as part of Xcode lldb module. In all likelihood, if we
encounter this situation, the developer is using a custom Python install
(e.g., via MacPorts or Homebrew).
* Return null from VM.mainView if no view exists
* Retry in connectToServiceProtocol if a view is not yet available
* Do not explicitly call exit from the benchmarks - it will not cleanly shut down the engine
* Update gradle example to support x86 in debug mode.
Changed the Flutter Gradle plugin a bit to better fit in with the
Android build.
