为什么我的Flutter BottomSheet给我一个GestureDetector错误？

Question

我有一个问题，这个BottomSheet，它工作得很好，但只要我点击它，我就会得到一个错误......

bottomSheet: showBottomSheet
        ? BottomSheet(
            enableDrag: true,
            onClosing: () {},
            builder: (ctx) => Container(
              height: 200,
              width: double.infinity,
              color: Colors.red,
            ),
          )

为什么会出现这个错误？

════════ Exception caught by gesture ═══════════════════════════════════════════
The following NoSuchMethodError was thrown while handling a gesture:
The getter 'status' was called on null.
Receiver: null
Tried calling: status

When the exception was thrown, this was the stack
#0      Object.noSuchMethod  (dart:core-patch/object_patch.dart:53:5)
#1      _BottomSheetState._dismissUnderway 
package:flutter/…/material/bottom_sheet.dart:187

package:flutter/…/gestures/recognizer.dart:182
...
Handler: "onEnd"
Recognizer: VerticalDragGestureRecognizer#22607
    debugOwner: GestureDetector
    start behavior: start

我需要添加什么？我想我需要添加一个OnDragEnd功能？ 请帮助，谢谢。

如上所述，只需将 enableDrag: false, 而且会有效果。
