Could you run flutter doctor – Degenerate

Answer 1

enableDrag is not available in showModalBottomSheet. I don't think it was ever available in stable channel. According to comments from the link at that time it was available in Master channel. But second answer from that link works well

builder: (context) => GestureDetector(
                    onVerticalDragDown: (_) {},
                    child: ...,

here is documentation to showModalBottomSheet . You can always tap into the showModalBottomSheet and customise it.. According to doc

BottomSheet, which becomes the parent of the widget returned by the function passed as the builder argument to showModalBottomSheet.

and BottomSheet has enableDrag parameter.
