I get the following error when calling the CupertinoActionSheet when implementing SingleChildScrollView on my stateful widget:

_RenderCupertinoAlertActions object was given an infinite size during layout.
The relevant error-causing widget was
CupertinoActionSheet
lib\main.dart:82
The following RenderObject was being processed when the exception was fired: _RenderCupertinoAlertActions#56898 relayoutBoundary=up19 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
RenderObject: _RenderCupertinoAlertActions#56898 relayoutBoundary=up19 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
