Checksum validation is intended only as a performance improvement.
Checksum de-serialization errors (typically framework version mismatch) are
expected on framework updates and shouldn't be user-visible except for
informational purposes when --verbose is set.
Adds the app entrypoint as a key in the checksum file.
This change eliminates the assumption that checksummed files change when
the main entrypoint changes. In the case where there are two
entrypoints, a.dart and b.dart and a.dart imports b.dart and b.dart
imports a.dart, building the app with entrypoint a.dart followed by a
build of the app with entrypoint b.dart would result in the same
files list and checksums, but should invalidate the build.
Extract a Snapshotter class that can be shared between FLX snapshotting,
AOT snapshotting, and assembly AOT snapshotting. Allows for better
testability of snapshotting logic.
* Extracts script snapshotting used in FLX build.
* Adds tests for snapshot checksumming, build invalidation/skipping.
Remaining work: disentangle + extract AOT snapshotting and Assembly AOT
snapshotting logic from build_aot.dart.
This change re-introduces skipping AOT snapshot builds if input sources
and outputs have not changed since the last snapshot build, assuming a
build for the same platform in the same build mode.
This reverts commit 3d5afb5a81.
It includes the following changes relative to the original:
1. Include the entrypoint source in the checksums
2. include the build mode in the checksums
3. include the target platform in the checksums
* Revert "Fix a typo in the saved certificate error message (#11640)"
This reverts commit bfda885a9d.
* Revert "Rollback patch that broke microbenchmarks (#11616)"
This reverts commit 70fe6f4c23.
* Revert "Extract snapshotting logic to Snapshotter class (#11591)"
This reverts commit 309a2d78fb.
* Revert "Minor whitespace formatting fix (#11590)"
This reverts commit bf69c3c69b.
* Revert "Avoid rebuilding snapshots if no change to source (#11551)"
This reverts commit 74835db563.
This change re-introduces skipping snapshot builds if input sources (and
outputs) have not changed since the last snapshot build, with a bugfix
to include the entry-point source in the checksum used to check whether
rebuild can be skipped. This ensures that the following sequence
invalidates the cached build, resulting in two snapshot builds:
flutter build ios lib/foo.dart
flutter build ios lib/bar.dart
This reverts commit 3d5afb5a81.
Previously, the snapshot file was recomputed on every build. We now
record checksums for all snapshot inputs (which are catalogued in the
snapshot dependencies file output alongside the snapshot) and only
rebuild if the checksum for any input file (or the previous output file) has
changed.
`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
**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.
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
* 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
* 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
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.
This removes direct file access from within flutter_tools
in favor of using `package:file` via a `FileSystem` that's
accessed via the `ApplicationContext`.
This lays the groundwork for us to be able to easily swap
out the underlying file system when running Flutter tools,
which will be used to provide a record/replay file system,
analogous to what we have for process invocations.
* Remove the workaround that pinned args to v0.13.6
This reverts most of the changes in commit 6331b6c8b5
* throw exception if exit code is not an integer
* rework command infrastructure to throw ToolExit when non-zero exitCode
* convert commands to return Future<Null>
* cleanup remaining commands to use throwToolExit for non-zero exit code
* remove isUnusual exception message
* add type annotations for updated args package
* convert pubGet to throw ToolExit on non-zero exit code
* convert commandValidator to throw ToolExit for non-zero exit code
* convert flutter commands to throw ToolExit for non-zero exit code
* use convenience method throwToolExit
* only show "if this problem persists" for unusual exceptions
* Rollback commits to get iOS into a stable state
This rolls back the following commits:
* 23c52fc (#6434)
* a97cf4b (#6433)
* e72e174 (#6428)
It also updates the engine to a newer revision that has the
necessary rollbacks in the engine repo.
Fixes#6458
* refactor _run to runCmd
* replace requiresProjectRoot getter with call to commandValidator
* replace requiresDevice getter with call to findTargetDevice
* trace command requires a debug connection, not a device
* inline androidOnly getter
* rename command methods to verifyTheRunCmd and runCmd
* move common verification into BuildSubCommand
* rename deviceForCommand to device
* rename methods to verifyThenRunCommand and runCommand
This change adds a top-level getBuildDirectory func and funcs for
android, aot, asset, ios build products.
Developers may now add a "build-dir" mapping to their
~/.flutter_settings (JSON format) config file. Output directory is
relative to the main flutter application directory.
This change also changes the default build directory for iOS builds to a
subdirectory of the configured build directory, 'build/ios' by default.
