This will catch issues like https://github.com/flutter/flutter/issues/44252, and this test is inspired by the `list_demo` sample app in https://github.com/flutter/flutter/issues/43083#issue-509586473 This is tested locally on a Moto G4 before and after the fix https://github.com/flutter/engine/pull/13710 The `average_frame_rasterizer_time_millis` of this test drops from ~5.4ms to ~4.9ms after that fix.
