Description
flutter: [WARNING]: Concurrent modification during iteration: Instance(length:18) of '_GrowableList'.
I was seeing this when selecting a variety of widgets (Column, Row, Stack, etc.)
Contributor guide
Research direction
No file, test, or entry point is identified. Start by reproducing the warning while selecting Column, Row, Stack, and other widgets in the inspector, then trace the concurrent iteration and confirm that widget selection no longer emits the warning.
