Flare animation inside SingleChildScrollView

[kasyrm]

Is it possible to use flare animation inside SingleChildScrollView? It works fine if I put it in a Container inside a Scaffold. When the widget hierarchy is more complex it starts to break, especially after adding SingleChildScrollView above the column that has FlareActor as one of its children.

The following assertion was thrown during performResize():
FlareActorRenderObject object was given an infinite size during layout.

This probably means that it is a render object that tries to be as big as possible, but it was put inside another render object that allows its children to pick their own size.
The nearest ancestor providing an unbounded width constraint is: RenderFlex#0d557 relayoutBoundary=up5 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
The constraints that applied to the FlareActorRenderObject were: BoxConstraints(0.0<=w<=Infinity, 0.0<=h<=30.0)
The exact size it was given was: Size(Infinity, 30.0)

See https://flutter.dev/docs/development/ui/layout/box-constraints for more information.

I have tried putting it inside a SizedBox or Container with specified size but it didn't have a ny effect.

I found a solution: fit had to be set to BoxFit.none and FlareActor had to be in a Container with assigned size.
