禁用向下拖动以关闭showModalBottomSheet [英] Disable drag down to close showModalBottomSheet

问题描述

如何禁用/逃脱底部模态中的向下拖动手势，以便用户可以在模态中进行交互而不会意外关闭模态?

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?

下面以实际的模态底部工作表进行了更新.

Updated below with the actual modal bottom sheet.

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

推荐答案

您可以尝试使用带有onVerticalDragStart =(_){}

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,
);
