* Enable flutter engine to also work with .*so files on android
We would like to be able to use native tools (e.g. simpleperf, gdb) with
precompiled flutter apps. The native tools work much better with *.so
files instead of the custom formats the Dart VM uses by default.
This CL adds support for being able to load the flutter app from an *.so
file on Android.
* Add sanity check to ensure we have either shared library or instruction snapshot (but not both)
This retains gamut correction (adjusting colors for screens with different capabilities), but does all blending and interpolation with sRGB-encoded values. That matches the behavior expected by most users, as well as the behavior of nearly all other systems. It also greatly simplifies the EGL code.
A future Skia change will make this behavior more of a first-class citizen, so some of these implementation details will change again, but the behavior will not. The bulk of this change (elimination of complication from the GL surface code) is permanent - it's just the SkColorSpaceXformCanvas that will be replaced.
With the update to HEAD of the Fuchsia buildtools repo, the new clang
toolchain picked up caused link-time breakage in android x86_64
libFlutter.so builds.
Sample log:

This reverts commit 8ad42f0dae3cb1267c2b9ab99db80e4696ddbc3d.
* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5
This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb
which disables -Wtautological-constant-compare temporarily until
https://reviews.llvm.org/D39462 lands in clang. This is in line with
Fuchsia's compiler options.
* Apply clang-format diffs
No logical changes. This applies clang-format from the latest Fuchsia
buildtools to the engine codebase.
* Read core platform kernel file during Dart initialization.
Currently service isolate is initialized from the source code parsed by VM.
This CL changes it so service isolate created during Dart initialization
is created from the kernel platform.dill file if it is present in the application
bundle. Then this platform kernel file is kept in dart_init module and reused
for application sciprt isolates.
* Reformat and merge
* Use accessor method
* Avoid passing running_from_kernel param. Add TODO for cleanup. Rename param.
By adding these events the new developer centric timeline will be able
to identify and correlate events related to the different stages of the
drawing pipeline.
Roll Dart to 62045a4590a333ae557f8f261a909ee75449cd70
Skia tracing is extremely useful for internal debug, but reduces the
amount of space available in the Dart Timeline buffers.
Disable skia tracing by default and expose them via the --trace-skia
flag.
* Fix remaining ftl->fxl conversions
The previous scripting pass at this did not account for objective c file endings
* Update tonic DEPS reference to the post-fxl version
- Assumes only the Dart VM is interested in idle notification.
- Gives the VM the time remaining in each frame.
- Gives the VM 100ms if there is no pending frame.
Issue flutter/flutter#9594
* Add back launch screen view until first frame on iOS
* improvements
* Move callback plumbing from ios surfaces to the gpu rasterizer. Didn’t wire java JNI yet.
* Android JNI

This reverts commit dd2fb3c04bb090915b698266ace8680d2747c9db.
* Revert "Revert "Switch to new encode API on SkPixelSerializer (#3892)" (#3894)"
