ScrollablePositionedList: every item gets rebuilt when adding an entry at 0

[imtoori]

Every widget children widget gets rebuilt when adding a child at position 0.

If I try to add a child at the end of the list only the new widgets are built.

I tried to add a key, but it doesn't help.

Sounds like findChildIndexCallback needs to be implemented. https://api.flutter.dev/flutter/widgets/SliverChildBuilderDelegate/findChildIndexCallback.html

Faced the same issue. Is there any updates?
