Flutter：如何防止意外地拖动单层Crollview的孩子，而不是滚动而不是滚动？

Question

我在单个单元格式内有可拖动的小

         LongPressDraggable(
            delay: Duration(milliseconds: 200),
            axis: Axis.vertical,
            data: block,
            feedback: Opacity(
              opacity: kScheduledBlockFeedbackOpacity,
              child: Material(
                elevation: 10.0,
                shadowColor: Colors.black,
                child: scheduleBlock(block, scheduledBlockFeedbackColor),
              ),
            ),
            child: GestureDetector(
              onTap: () {
                print('onTap triggered 1');
                // go to details
                ...
              },
              child: block.action == 'pulling'
                  ? Opacity(opacity: kScheduledBlockFeedbackOpacity, child: scheduleBlock(block, scheduledBlockColor))
                  : scheduleBlock(block, scheduledBlockColor),
            ),

            childWhenDragging: Container(),
            onDragStarted: () {
              ...
            },
            onDragUpdate: (DragUpdateDetails d) {
              ...
            },
            onDragEnd: (DraggableDetails d) {
              ...
            })

部件GETUREDETECTOR的ONTAP不会触发。即使将延迟设置为0，也可以使其与可拖动相同。

我该如何解决这个问题？还是有更好的方法可以防止在单层Crollview中拖动可拖动，而不是滚动？

                          ),
                        )

如果我正确理解它，您想禁用儿童在singlechildscrollview（）内的滚动属性吗？

尝试设置物理 neverscrollablesscrollphysics（）在您的孩子可滚动小部件中。
