* TapGestureRecognizer no longer adds the pointer after it resets.
* Adds an assertion to make sure TapGestureRecognizer.startTrackingPointer is never called when _down is null
When performing a hot restart, collect isolates without an attached flutter view and send a kill signal. These must have been spawned by running main, so restarting without removing them leads to isolate duplication.
When performing a hot reload, ensure that we send a reloadSources command to every isolate and not just uiIsolates.
This converts Diagnosticable to be a mixin instead of an abstract class, so that it can be used to add diagnostics to classes which already have a base class.
It leaves in place the DiagnosticableMixin mixin, since there are some plugins that are still using it, and removing it would mean that those plugins wouldn't work with master branch Flutter anymore. DiagnosticableMixin will be removed once this mixin version of Diagnosticable makes its way to the stable branch.
Updates VisualStudio and VisualStudioValidator to use constructors instead of global injection. Updates VisualStudio test cases to prefer FakeProcessManager
Updates build_windows test to work without injected VisualStudio
This adds a sample for InheritedNotifier, and converts a couple of other samples to be DartPad samples. I also added a new sample template stateful_widget_material_ticker, which adds a TickerProviderStateMixin to the state object so that animation controllers can be created there easily.
When the AndroidDevice checks for the current API version, it isn't handling a null response. While we can refuse to run on API levels that are unsupported, we should probably assume that a null response = lowest possible API level and allow these to run.
The Azure bot detection can take up to a second to determine if a client is/isn't a bot. To prevent this from slowing down all flutter commands, we can cache the results in the persistent tool state - since we don't expect the same client id to ever become a bot or stop being a bot
Previously the AdbLogReader did async setup in the StreamController.onListen callback, specifically it would query the api version and start the adb process. If the log subscription was cancelled before this setup completed, then the log output could (haven't confirmed) get added to a closed controller, causing the above state error.
