Update all versions, specifically file which fixes some bugs that caused tests to fail if run in different orders: - systemTemp directories created by MemoryFileSystem will allot names based on the file system instance instead of globally. - MemoryFile.readAsLines()/readAsLinesSync() no longer treat a final newline in the file as the start of a new, empty line. - RecordingFile.readAsLine()/readAsLinesSync() now always record a final newline.
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_data.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.
