This attempts to reland https://github.com/flutter/flutter/pull/126848 This was reverted because it made some unexpected changes to our perf measurements. After landing https://github.com/flutter/flutter/pull/127900, we have much less noise in our benchmarks, so I'd like to reland this and see if there is still a significant measurement difference.
ios_platform_view_test
A simple app contains:
- A home with a button that pushes a new page into the scene.
- A page contains a platform view, a button, and a text.
- Press the button will update the text.
We use this app to test platform views in general such as platform view creation, destruction, and thread merging(iOS only).
