Andrew Kolos 2b8f2d0504 Add API for discovering assets (#118410 ) * add asset manifest bin loading and asset manifest api * use new api for image resolution * remove upfront smc data casting * fix typecasting issue * remove unused import * fix tests * lints * lints * fix import * revert image resolution changes * Update image_resolution_test.dart * Update decode_and_parse_asset_manifest.dart * make targetDevicePixelRatio optional * Update packages/flutter/lib/src/services/asset_manifest.dart Co-authored-by: Jonah Williams <jonahwilliams@google.com> * Update packages/flutter/lib/src/services/asset_manifest.dart Co-authored-by: Jonah Williams <jonahwilliams@google.com> * fix immutable not being imported * return List in AssetManifest methods, fix annotation import * simplify onError callback * make AssetManifest methods abstract instead of throwing UnimplementedError * simplify AssetVariant.key docstring * tweak _AssetManifestBin docstring * make AssetManifest and AssetVariant doc strings more specific * use List.of instead of List.from for type-safety * adjust import * change _AssetManifestBin comment from doc comment to normal comment * revert to callback function for onError in loadStructuredBinaryData * add more to the docstring of AssetManifest.listAssets and AssetVariant.key * add tests for CachingAssetBundle caching behavior * add simple test to ensure loadStructuredBinaryData correctly calls load * Update asset_manifest.dart * update docstring for AssetManifest.getAssetVariants * rename getAssetVariants, have it include main asset * rename isMainAsset field of AssetMetadata to main * (slightly) shorten name of describeAssetAndVariants * rename describeAssetVariants back to getAssetVariants * add tests for TestAssetBundle * nits * fix typo in docstring * remove no longer necessary non-null asserts Co-authored-by: Jonah Williams <jonahwilliams@google.com>		2023-01-26 19:05:00 +00:00

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.
