liyuqian c63dcf3bcd Make shader warm-up async so it can handle image (#28687 ) ## Description This moves another 15-20ms from the animation jank of one of our important client to the startup latency. Unfortunately, this is probably not captured in our current benchmarks (presumably some other bottlenecks overshadow this shader compilation in the worst_frame benchmark). Considering that drawing images is such a common operation, maybe we should add one in the future to benchmark this. We need this PR to land soon for our client because this changes the API to return Future. ## Related Issues https://github.com/flutter/flutter/issues/813		2019-02-28 20:07:55 -08:00

Macrobenchmarks

Performance benchmarks using flutter drive.

Cull opacity benchmark

To run the cull opacity benchmark on a device:

flutter drive --profile test_driver/cull_opacity_perf.dart

Results should be in the file build/cull_opacity_perf.timeline_summary.json.

More detailed logs should be in build/cull_opacity_perf.timeline.json.
