* Introduce stubbed `exclusive` parameter to `File.create`-overridden method. This is to soften landing of a breaking change https://github.com/dart-lang/sdk/issues/49647
microbenchmarks
To run these benchmarks on a device, first run `flutter logs' in one window to see the device logs, then, in a different window, run any of these:
flutter run --release lib/gestures/velocity_tracker_bench.dart
flutter run --release lib/gestures/gesture_detector_bench.dart
flutter run --release lib/stocks/animation_bench.dart
flutter run --release lib/stocks/build_bench.dart
flutter run --release lib/stocks/layout_bench.dart
The results should be in the device logs.
Avoid changing names of the benchmarks
Each microbenchmark is identified by a name, for example, "catmullrom_transform_iteration". Changing the name of an existing microbenchmarks will effectively remove the old benchmark and create a new one, losing the historical data associated with the old benchmark in the process.
