Since this is currently only meant to be used by the embedding internally, the setter in Objective-C is only exposed via the FlutterDartProject private class extension. Unit tests have been added to the shell_unittests harness.

Ensure that we always pull in the ensure_fuchsia_sdk gn variable.
Fixes breakage introduced in flutter/engine#11016 when building outside
of a Fuchsia tree (e.g. in a stock Flutter engine tree0 on macOS hosts.
When building Fuchsia on macOS hosts, ensure that we reference the
correct clang toolchain path. This patch also prevents bitcode
compilation on Fuchsia tree builds on macOS.
libapp.so contains compiled application Dart code. On most Android systems,
this library can be loaded by calling dlopen("libapp.so"), which will search
Android's default library directories.
On some Android devices this does not work as expected. As a workaround, this
patch provides a fallback path to libapp.so based on ApplicationInfo.nativeLibraryDir.

This converts the libtxt Paragraph and ParagraphBuilder classes into
interfaces with Minikin and SkShaper/SkParagraph based implementations.
Use the --enable-skshaper GN flag to select the Skia shaper implementation
at build time.
Adds --observatory-host, which allows callers to specify the localhost
IP binding directly. Allows users to set 0.0.0.0 or the host IP address
as is possible in the standalone VM, rather than restricting users to
loopback.
We retain the default behaviour of binding to loopback since the vast
majority of observatory use-cases involve local access (e.g. host tests
on flutter_tester) or port-forwarded local access (e.g. flutter driver
device tests). However, some scenarios, such as QA test labs, may
benefit from binding to a publicly-accessible IP address.
Using it, a Flutter app can monitor missing frames in the release mode, and a custom Flutter runner (e.g., Fuchsia) can add a custom FrameRasterizedCallback.

Need review as soon as possible so we can merge this before the end of May to catch the milestone.
Tests added:
* NoNeedToReportTimingsByDefault
* NeedsReportTimingsIsSetWithCallback
* ReportTimingsIsCalled
* FrameRasterizedCallbackIsCalled
* FrameTimingSetsAndGetsProperly
* onReportTimings preserves callback zone
* FrameTiming.toString has the correct format
This will need a manual engine roll as the TestWindow defined in the framework needs to implement onReportTimings.
This does not actually import the runners into the engine. It only sets up the targets so they need no modifications are necessary when the migration is done. The engine has been verified to build in both buildroots.
If the mapping callback is not set or it the callback returns invalid data, ICU initialization will be embedder responsibility.
This affects all embedders and the following have been audited:
* Android: Via a symbol mapping.
* iOS: Via a file mapping.
* Embedder: Via a file mapping.
* Fuchsia: Via a VMO mapping
* Test shells and Flutter tester: Via file mapping with ICU data needing to be next to the executable.
Some components in the Flutter engine were derived from the forked blink codebase. While the forked components have either been removed or rewritten, the use of the blink namespace has mostly (and inconsistently) remained. This renames the blink namesapce to flutter for consistency. There are no functional changes in this patch.
Allow Flutter to automatically dump the skp that triggers new shader compilations. This is useful for writing custom ShaderWarmUp to reduce jank. By default, it's not enabled to reduce the overhead. This is only available in profile or debug build.
Later, we can add service protocol support to pull the skp from the client to the host. Currently, it works fine for Android-based devices (including our urgent internal clients) where we can `adb shell` into the cache directory.
Link dart:* sources into engine for debugger source support
Currently, dart:* libraries appear to have no source in
debuggers like Observatory. With this change, these sources will be
available in debug mode applications. Sources for dart:* libraries are
lazily loaded on a script-by-script basis.
Refer to https://dart-review.googlesource.com/c/sdk/+/93375 for the Dart
SDK change.
Prior to this the Android embedder code would extract the icudtl.dat asset out
of the APK and write it to local disk during the first startup of the app.
This change will make that work unnecessary and eliminate the risk of ICU
failures due to errors in the extraction process.
This reverts commit 524a12d0468e1a536d74f866796e1cdd7ccaa35e.
Reason for revert: broken in AOT mode.
@pragma('vm:entry-point') placed on a function only instructs
the compiler to retain the function itself, but does not tell
compiler to generate and retain tear-off for this function.
In this PR _runMainZoned was marked as an entry-point but C++
code was trying to tear it off and use a closure, instead of
invoking it directly, which is not supported.
In Dart 2, runtime checked mode has been eliminated. Many of these type
checks have been moved to static compile-time checks, the remainder are
enforced at runtime, and are no longer optional.
