Disable drag down to close showModalBottomSheet

问题

How do I disable / escape drag down gesture within the Bottom Sheet Modal so the user can interact within the modal without accidentally closing the modal?

Updated below with the actual modal bottom sheet.

return showModalBottomSheet(
    context: context,
    builder: (BuildContext context) {
        ...
    }
}

回答1:

you can try to wrap builder's result with GestureDetector with onVerticalDragStart = (_) {}

showModalBottomSheet(
  context: context,
  builder: (context) => GestureDetector(
    child: **any_widget_here**,
    onVerticalDragStart: (_) {},
  ),
  isDismissible: false,
  isScrollControlled: true,
);

回答2:

Set enableDrag to false

bool enableDrag

If true, the bottom sheet can dragged up and down and dismissed by swiping downwards.
