Refactor has changed the behavior of AnimatedList (Regression) #115040
Description
Steps to Reproduce
- Execute
flutter runon the code sample - Compare the width of the colored boxes
Expected results:
The red box (AnimatedList) should not be visible
Actual results:
The red box (AnimatedList) is visible and occupies a part of the Row.
The regression was caused by commit #113793.
#113793 was only supposed to be a refactor, so something must have gone wrong because the behavior changed.
