* working on making a faster flutter run restart
* clean up todos; fire events on isolate changes
* use the Flutter.FrameworkInitialization event
* review comments
* iOS tools cleanup
1) Fix `flutter install` on both device and simulator to refer to the actual
bundle and not just the .generated folder
2) Fix `flutter run` on device to actually run vs just installing
Still TODO:
1) Discovered that isAppInstalled on iOS simulator always reports true,
meaning it'll never actually try to install the app.
Fixes#3947Fixes#1823
This also fixes some related problems affecting "flutter run":
* FLXes built during AndroidDevice.startApp need to match the build mode
* APKs should always be rebuilt if the build mode uses AOT compilation
* rename service_protocol.dart to protocol_discovery.dart
* add a wrapper around the obs. protocol
* use json-rpc in run
* consolidate obs. code; implement flutter run --benchmark
* review comments
Host tools can be found in the artifact cache directory for the host platform.
If a developer wants to use a local engine build instead, then provide an
--engine-build flag that selects the specific engine build variant.
* more terse flutter upgrade
* fix an issue when updating and the engine update code has changed
* call flutter precache; add a --no-color hidden option
* fix a lint related to getters/setters
The new name format is "DEVICE_TYPE_NAME (Flutter)". For example:
iPhone 6 (Flutter)
iPhone 6s Plus (Flutter)
The names are taken from `xcrun simctl list --json devicetypes`.
Fixes#2682
flutter start's method of finding devices to run the app on is not suitable for flutter drive.
This commit also refactors several tool services to allow mocking in unit tests.
