ProcessResult.stdout has static type dynamic so for
inference to infer proper type argument for the map
invocation we need to cast stdout to String explicitly.
Fixes#17163
This updates the Android build to declare the kernel compile depfile as
an output and its contents as inputs when running with --preview-dart-2
(the default mode).
The 'flutter build aot' command behaves differently depending on whether
it's running in Dart 1 or Dart 2 mode:
* Dart 1: the entrypoint Dart file (typically main.dart) is passed
directly to gen_snapshot, which then emits snapshot.d, whose contents
list the transitive closure of Dart dependencies (input files) for the
snapshot. snapshot.d is a declared output, its contents (plus
gen_snapshot itself) constitute the set of input files to the Gradle
build action.
* Dart 2: then entrypoint Dart file (typically main.dart) is first
compiled with the Dart kernel frontend. This emits kernel_compile.d,
whose contents list the transitive closure of Dart dependencies (input
files) for the kernel 'dill' output file. This 'dill' file is then
passed to gen_snapshot, which emits snapshot.d, whose contents are
empty. As of this change, both snapshot.d and kernel_compile.d are
declared outputs, and their contents (plus gen_snapshot and the
frontend compiler themselves) constitute the set of input files to the
Gradle build action.
This fixes a bug wherein profile/release AOT outputs were not
invalidated due to snapshot.d being empty, and kernel_compile.d being
ignored. This was introduced during recent refactoring of the AOT build
code, wherein the kernel compile and gen_snapshot actions were changed
to emit independent depfiles (previously one stomped -- or failed to --
on the other's output).
* Configure Cirrus CI
* Read file directly instead of shelling a command
* Wait for all streams to finish
* Add LTR `textDirection`
Since `RenderFlex#_debugHasNecessaryDirections` requires it when `direction` is horizontal and there are multiple children.
Previously, we were incorrectly passing --vm_snapshot_data and
--isolate_snapshot_data options to gen_snapshot in assembly AOT builds.
These only make sense in AOT blob snapshot mode (alongside
--vm_snapshot_instructions and --isolate_snapshot_instructions).
There's very little code-sharing between the two, and what little there
is is concentrated in the GenSnapshotClass and the fingerprint
reading/writing utility methods.
This enables support for a `flutter_test_config.dart` configuration file,
which will be discovered and handed the responsibility of running the
test file (thus allowing it to run pre-test setup on a project level).

This de-duplicates assembly AOT configuration between Android and iOS,
and makes it easier to adjust parameters for 32-bit iOS (which, like
32-bit Android, requires --no-integer-division) in an upcoming patch.
iOS debug builds always run in interpreted mode whether on device or on
simulator. In both cases, we can skip snapshotting and link against an
empty App.framework. Previously, we did this for iOS simulator builds.
This does the same for device builds.
Previously, debug iOS builds used gen_snapshot to generate a core
snapshot, then used 'xxd' to generate C files containing the snapshot
data in buffers named kDartVmSnapshotData and kDartIsolateSnapshotData,
which are then compiled/linked into App.framework. This is unnecessary
since the VM compiled into Flutter.framework already contains this data.
Bugfix: Moves AOT snapshot input verification past where the last input
is added to the inputs list.
Cleanup:
* Extracts _isValidAotPlatform method.
* Moves non-platform-specific logic to the top.
* Moves variable declaration closer to first use, and inlines to a
narrower scope where possible.
This relands #17136, which was reverted in #17142 due to breakage in
on-device iOS debug builds.

Cleanup:

* Moves non-platform-specific logic to the top.
* Moves variable declaration closer to first use, and inlines to a

* Add a `matchesGoldenFile()` async matcher that will match
a finder's widget's rasterized image against a golden file.
* Add support for pluggable image comparison backends
* Add a default backend that does simplistic PNG byte
comparison on locally stored golden files.
* Add support for `flutter test --update-goldens`, which will
treat the rasterized image bytes produced during the test
as the new golden bytes and update the golden file accordingly
Still TODO:
* Add support for the `flutter_test_config.dart` test config hook
* Utilize `flutter_test_config.dart` in `packages/flutter/test`
to install a backend that retrieves golden files from a dedicated
`flutter/goldens` repo

Moves the kernel compile step to the beginning of the AOT build in a
separate method. This is pre-factoring for iOS universal builds where
the kernel build happens once, but we then snapshot twice: once for
armv7 and once for arm64.
This also writes dependencies to build/kernel_compile.d rather than
build/aot/snapshot.d, since that is immediately overwritten by
gen_snapshot.
When forwarding all ports, run a test connection to each Dart VM instance, stopping port forwarding if the connection fails.
Also does the same for any batched calls that hit all Dart VM instances.
This is a simple refactoring with no functional changes. We now reuse
the existing _isBuildRequired() and _writeFingerprint() functions and
share them with script snapshotting rather than reimplementing their
logic.
Changes the signatures of both to support multiple output files (as
required for AOT snapshotting).
Fixes a bug introduced in 82f969ff05 where
the depfile used for AOT snapshotting, useful in particular for skipping
gen_snapshot when inputs/outputs haven't changed since the last build.
