Make flutter_tester support multithreaded testing, and run all Dart tests in both single and multithreaded configurations
This also modifies Shell::GetUIIsolateLastError() and Shell::EngineHasLivePorts() so that they must be called from the UI task runner.
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.
Previously AOT compiled Dart code would be packaged as a group of assets
within the APK. This has been replaced by a single ELF library containing
the same data.
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.
The ICU data is packaged within libflutter.so, and the engine uses
dlsym(RTLD_DEFAULT) to look up the ICU data symbols in the libraries
loaded by the process.
This approach apparently fails on some Xiaomi devices. If RTLD_DEFAULT
can not find the symbols, then the platform will pass the path to the
libflutter.so library so the engine can use that to resolve the symbols.
Fixes https://github.com/flutter/flutter/issues/28208
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.
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.
