* 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.
