warmUpOnCanvas abstract method Null safety
- Canvas canvas
Trigger draw operations on a given canvas to warm up GPU shader compilation cache.
To decide which draw operations to be added to your custom warm up
process, consider capturing an skp using
flutter screenshot --observatory-uri=<uri> --type=skia and analyzing it with
debugger.skia.org/. Alternatively, one may run the app with
flutter run --trace-skia and then examine the raster thread in the
observatory timeline to see which Skia draw operations are commonly used,
and which shader compilations are causing jank.
