════════ Exception caught by rendering library ═════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
RenderUiKitView 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 height constraint is: RenderFlex#dbb0a relayoutBoundary=up2 NEEDS-LAYOUT NEEDS-COMPOSITING-BITS-UPDATE OVERFLOWING
...  parentData: offset=Offset(30.0, 0.0) (can use size)
...  constraints: BoxConstraints(0.0<=w<=354.0, 0.0<=h<=840.0)
...  size: Size(354.0, 840.0)
...  direction: vertical
...  mainAxisAlignment: start
...  mainAxisSize: max
...  crossAxisAlignment: center
...  verticalDirection: down
The constraints that applied to the RenderUiKitView were: BoxConstraints(0.0<=w<=354.0, 0.0<=h<=Infinity)
The exact size it was given was: Size(354.0, Infinity)
