This patch adds a default shader warm up process which moves shader compilation from the animation time to the startup time. This also provides an extension for `runApp` so developers can customize the warm up process.
This should reduce our worst_frame_rasterizer_time_millis from ~100ms to ~20-30ms for both flutter_gallery and complex_layout benchmarks. Besides, this should also have a significant improvement on 90th and 99th percentile time (50%-100% speedup in some cases, but I haven't tested them thoroughly; I'll let our device lab collect the data afterwards).
The tradeoff the is the startup time (time to first frame). Our `flutter run --profile --trace-startup` seems to be a little noisy and I see about 100ms-200ms increase in that measurement for complex_layout and flutter_gallery. Note that this only happens on the first run after install or data wipe. Later the Skia persistent cache will remove the overhead.
This also adds a cubic_bezier benchmark to test the custom shader warm up process.
This should fix https://github.com/flutter/flutter/issues/813 (either by `defaultShaderWarmUp`, or a `customShaderWarmUp`).

Google-internal embedders have been updated to an engine version that
includes the above change. These were initially updated in engine roll
flutter/flutter#26252, but broke internal embedders.
We should re-enable use of the const constructor in those cases once
internal embedders are updated.

* the onStart callback will report the location of the pointer where it wins the gesture arena by default instead of the pointer down location. Fixes all tests related to changing this default value.
* Adds start behavior option to the drag gesture recognizer and makes it the default option when a drag gesture recognizer is created. Also fixes all the tests to work correctly with the new default behavior.
This reverts commit 8acc058cf1.
Reverts #25483
Reason for revert: it seems to break the flutter_gallery_instrumentation_test post-submit test.

Make the examples/catalog instructions a bit less confusing:
* Make the README.md file provide explicit instructions about how to
run each example.
* Try to clarify that the lib/main.dart message is instructional and
not an error message.
Additionally, adjust examples/layers/lib/main.dart to be consistent
with examples/catalog/lib/main.dart.
Fixes#22640.
Testing Done:
* Ran `flutter run` from examples/catalog and from examples/layers,
saw the updated message.
Should fix#22226.
Code introduced in #20890 caused a regression that broke color flooding animations in a BottomNavigationBar that has BottomNavigationBarType.shifting.
The original issue (#19653) dealt with background color changes not occurring until another tab was selected. The result is that the background color instantly changes whenever the state changes and when the widget changes, instead of allowing a new widget to animate the background color change.

Coverage 0.12.3 includes a fix for dart-lang/coverage#194, which was
causing errors on the flutter build bots.
Linter was updated automatically as a side effect of running
`flutter update-packages --force-upgrade`.

Adds a Fuchsia compatibility function that allows for connecting to a
specific Isolate by name when running Flutter Driver on a Fuchsia
device. This will check over multiple Dart VM's in an attempt to find
an Isolate by its name.
A few changes:
* Remove the search tip (it relies on searching for the new keyword which we no longer use)
* Remove mentioning of examples that are either stale or only used for internal purposes (such as test)
* Cross-link to the samples repo
Introduce an overall material "color scheme" and to make it possible to redefine how a component's visual properties bind to the color scheme and to the existing material Theme.
Improve Swift usage in platform_channel_swift some more
Make a bunch of changes that willlarche requested in
https://github.com/flutter/flutter/pull/21712:
* Use `static let` within `enum` namespaces for String constants.
* Use `guard` for early exits and to avoid forced unwrapping.
* Explicitly qualify a selector.
* Fix a retain cycle by using a weak reference.
Make platform_channels_swift use more idiomatic Swift
* Remove semicolons.
* `if (condition)` => `if condition`.
* `Class.init(...)` => `Class(...)`.
* Remove `break` statements from `switch` cases.
* Remove some unnecessary uses of `self`.
* Make CupertinoApp and MaterialApp both use WidgetsApp for Navigator
* Make CupertinoApp and MaterialApp const constructors
* Make WidgetsApp routes aware
* Update tests
* Improve documentation and clean up code.
* Remove "Note that".
The phrase "note that" is basically meaningless as a prefix to an
otherwise fine sentence.
The average frame time of page transitions on Moto G4 is now very
close to 16ms (the last 10 measurements on our dashboard are
between 15.5ms to 16.7ms and half of them are below 16ms).
It is now much faster than when we disabled it (which was at about
35ms). So I think that we should be able to enable it by default.
I'll leave the flag there until we implement the retained rendering
to bring the frame time comfortably below 16ms.
See https://github.com/flutter/flutter/issues/13736
* Fixes resulting from audit of issues links
I looked at every link to GitHub in our repo. For cases where we had a TODO that was waiting for a bug to be fixed, and the bug has now been fixed, I applied the pending change. For cases where the link was out of date, I updated the link.
* Update run_test.dart
skip this test again since it failed on linux and macos bots
* Reland "Roll engine to version b148e628ec86b3a9a0382e0bcfae73f0390a8232 (#20427)"
This is a re-land with downgraded `package:flutter_gallery_assets`
version.
* Downgrade package:flutter_gallery_assets to 0.1.4
* Change engine.version to 81baff97c29bb08cbf8453a3f9042c5813f84ad3 (which contains an additional fix)
* Change engine.version to e3687f70c7ece72000b32ee1b3c02755ba5361ac (since mac tarballs are corrupted on earlier commit)
Reason for revert: The package:flutter_gallery_assets has removed some images which are required for the examples/flutter_gallery, so the gallery build is failing (only discovered after landing, since gallery doesn't seem to get built during github PR presubmit checks)
This CL
* rolls `engine.version` to flutter/engine@b148e628 (which includes dart sdk 2.1.0-dev)
* rolls `goldens.version` to flutter/goldens@6c45fafdf (which includes updates due to skia changes in engine)
* changes `platform.dill` to `platform_strong.dill` in various places due to flutter/engine@a84b210b
* adds explicit `environment: sdk: ">=2.0.0-dev.68 < 3.0.0"` constraints to `pubspec.yaml` and `pubspec.yaml.tmpl` files (since pub defaults to `<2.0.0` if omitted)
* upgrades to newer versions of various 3rd party packages (to ensure transitive dependencies have `<3.0.0` sdk constraint)
* Upgrade everything except matcher.
* Roll matcher (and test)
* Adjust tests that depend on flutter:test directly to depend on a shim
* Require use of package:test shim and remove other references to package:test
Somehow I forgot to say "super.tap()" when calling "tap()" on the new
superclass, so it was just recursing infinitely but ended up actually
crashing on the first reuse of the finder.
The error was previously swallowed, I made this print it instead.
This removes the final traces of Travis and Appveyor from the Flutter tree.
I've updated the documentation and fixed a couple of places where scripts look for Travis, and eliminated the dart tools runningOnTravis function (which was unused anyhow).
There are places in the flutter script that used to look for the environment variable TRAVIS. We actually do want to continue to detect that we're running on Travis there, since in the plugins repo we still use Travis (for the moment). In any case, it's OK, because the CI environment variable is set on all of the CI bots (Cirrus, Travis, and Appveyor).
FastLane doesn't have a setup_cirrus equivalent to setup_travis, but it actually doesn't matter there either, since it doesn't do Travis-specific things, and it also looks for the CI environment variable.
Our Cirrus Windows tests were not really working: they reported success even when failing.
This should fix several problems with the Cirrus Windows tests.
Changes:
- Move the SemanticsConfiguration update from RenderToggleable to each subclass, so that Switch can use toggled.
- Add image, liveRegion, toggled properties to Semantics, SemanticsConfiguration, SemanticsNode
- Added semanticsLabel and excludeFromSemantics to Image (the latter so that we avoid creating a semantics node)
- Added onDismiss semantics action which maps to the modal escape on iOS and dismiss action on Android.
- Added dismiss and liveRegion to snackbar widget
- Updated custom painter semantics to handle image, liveRegion, toggle
- Updated relevant tests to use correct flag/action
Generated.xcconfig is only required at build time for iOS apps. In the
flutter create project template and example apps, Generated.xcconfig was
previously marked as a resource to be bundled into the built app.
This uses @kevmoo's completion package to do command line completion for flutter, and a new command "bash-completion" (with alias "zsh-completion") that will output the necessary shell script setup code, and adds the hidden command "completion" that does the actual completion.
Because it adds a dependency, I also had to do flutter update-packages --force-upgrade.
Fixes#18988.
