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.
Fixes https://github.com/flutter/flutter/issues/35838
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.
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.
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.
- Switch core snapshot to Dart 2 and remove support for loading platform.dill.
- Remove support for loading script snapshots.
- Remove support for loading source.
- Remove settings and fix names to reflect the above.
- Remove support for loading the service isolate from source.
Eliminates support for running directly from sources or script snapshots. In
debug mode, we run from a kernel snapshot; in profile and release modes, we
link in AOT-compiled code.
Renames --dart-non-checked-mode to --disable-dart-asserts since checked mode
does not make sense in Dart 2.
