Closes https://github.com/flutter/flutter/issues/155131.
Not only did I rename the method, but I also changed the contract slightly - now `onSurfaceAvailable` is _only_ invoked _after_ `onSurfaceDestroyed` has been called. The cost is a single `boolean`, and it honestly makes the API make a lot more sense than someone having to track this themselves.
/cc @johnmccutchan (OOO), and @flutter/android-reviewers.
- **Add light and dark test back to FlutterView.java**
- **Migrate some but not all usages of Robolectric.setupActivity in FlutterViewTest.java**
- **Remove suppress warnings on tests that no longer need it, update documentation for ones that still need the suppression**
Fixes https://github.com/flutter/flutter/issues/154746
Partial work on https://github.com/flutter/flutter/issues/133151
- **add test back with no other changes**
- **Add legacy test and setup shadow**
2 and 3 of 5 flutter/flutter/issues/154746
Improved legacy testing by validating a fullscreen and non fullscreen codepaths.
Added `.git-blame-ignore-revs` because git was failing to give blame values with that file missing. I dont think I added a global config anywhere but adding an empty file should not cause a problem.
I've found a few instances where Vulkan worked correctly but surface control did not. lets add a debugging flag we can ask folks to try to narrow down the issue.
Part 1/5 for re adding tests documented in flutter/flutter/issues/154746

From local testing, the Adreno 630 returns VK_INCOMPLETE when compiling certain shaders with no other error messages. That is not a valid return code from vkCreateGraphicsPipeline and likely indicates severe problems with the driver.
@matanlurey:
> As of 2f6952657d, we are now printing a `W/FlutterView( 7775): API level 34 is too low to query bounding rects.` message which is not user actionable. Was this intended to stay in the merged PR? What value is it supposed to have?
@yaakovschectman:
> You might be right about that
Some android devices have only a single fast core. We set the threading affinity for UI/Raster to the fast core, which can lead to the UI/Raster being serialized on this thread. Instead, we should weaken /invert the affinity to "Not slow cores".

Customer money will see some benchmark regressions but they can deal.
Original Title: Add FlutterViewDelegate and BoundingRect methods
Check the bounding rect for caption bar when sending viewport metrics to
Flutter to account for freeform mode. Use the more recent
`getBoundingRects` over `getInsets`.
Tests will need to be kept separate until Robolectric publishes a
version that supports API level 35.
Roboletric tests for this pr will be part of google testing until then.

Reverts flutter/engine#54453
Not quite ready to remove Impeller Scene yet because I'm still porting
the animation functionality. Keeping it around allows me to switch back
and forth to compare without having to recompile the engine.
Over a month ago I said something like "we can revert this a couple of
weeks from now" in one of the Impeller meetings. But for better or worse
(better, I think), I ended up spending a ton of time trying to make the
PBR good first (which doesn't exist in this C++ version).
Previously this was using a zero EGLConfig handle in tests which use an AndroidContextGLImpeller that creates EGL surfaces. This apparently worked with older emulators, but the API 35 system image requires a real EGLConfig.
See https://github.com/flutter/flutter/pull/152498
Developers can control the backend in the following ways:
* **Do nothing**: Impeller with Vulkan is used where Vulkan is available with a fallback to Skia with OpenGL.
* **In `AndroidManifest.xml`, specify `io.flutter.embedding.android.EnableImpeller` as `false`**: Skia with OpenGL is used.
* **On the command line, specify `--no-enable-impeller`**: Skia with OpenGL is used.
Manifest options will take priority command line options when there is a conflict. This matches iOS behavior per https://github.com/flutter/flutter/issues/124049 (closed as WAI).
Fixes https://github.com/flutter/flutter/issues/149360
SurfaceTextureGetTransformMatrix returns a col-major 4x4 matrix. We used to convert it to a 3x3 matrix. Then when applying the transformation in the shader, I'd convert it back to a 4x4 matrix.
Instead of all this (potentially lossy) flip-flopping, store the matrix just as we get it in 4x4 form and perform the conversion just once if necessary. Today, it is necessary only in the Skia backend. SkM44 already has a converter to convert to and from a 3x3 SkMatrix. So, use that instead of rolling our own.
I spent a lot of time debugging these conversions and transformations because we had rolled our own and the printers seemed to dump in row-major order irrespective of storage order. This caused a lot of confusion.
No change in functionality. Hopefully, the next person debugging transformations has an easier go at this.
This removes support for "unobstructed platform views" on iOS - instead prefering to use the Android strategy of minimizing overlay layers, as this is generally more performant.
This decouples the Impeller on-by-default effort from the release schedule and [plugin migrations](https://github.com/flutter/flutter/issues/151018).
The plugin migration documented in [go/impeller-plugin-migration][plugin-migration] is still recommended and facilitates zero-copy texture transfers between OpenGL and Vulkan. To recap, the plugin migration is to move away from the OpenGL-only SurfaceTexture APIs in the plugin interface.
This patch facilitates rendering OpenGL textures in a Vulkan renderer using texture trampolining using a single device-device transfer on all devices that support Impeller using the Vulkan renderer.
The performance of this approach is more than acceptable but at the cost of an additional texture allocation and will serve as a fallback to the for any remaining unmigrated plugins (all first-party plugins will already be migrated when the Impeller is on by default and we are following up on the migration of the major third-party plugins as well).
This is a straight improvement to the current state of things were unmigrated plugins will render an empty quad.
No change in functionality. The updates:
* HeaderDoc comments have been added to the major rendering related TUs. However, not all comments are complete. I only documented the stuff I understood. For instance, it isn't clear how/why some subclasses use Attach/Detach while other use ProcessFrame. I intend to document as I go.
* Each package specific subclass is now in its own TU.
* Some subclasses used to be Skia specific. We added an Impeller variant but didn't rename to Skia TU. This has been patched.
Experimentally support merging UI and platform thread on Android/iOS. This works by changing the shell holder to set the UI thread to the platform thread. Several shell APIs that post messages from the platform to ui thread were changed to use RunNowOrPostTask to immediately call the UI task if the threads are the same.
Experimentally, this seems to work reasonably well if there are no platform views. On Android with TLHC it works fine either way, while iOS currently takes a big performance hit.
This can be opted into via a Plist:
```
<key>FLTEnableMergedPlatformUIThread</key>
<true/>
```
Or via AndroidManifest.xml:
```
<meta-data
android:name="io.flutter.embedding.android.EnableMergedPlatformUIThread"
android:value="true" />
```

Previously CreateEGLImage had been failing an assertion if an EGL display is not active on the calling thread. CreateEGLImage should not assert here because it could be called from a deferred task that runs after the raster thread has lost its EGL state.
