如何让 GestureDetector 在触摸 Flutter 中的空白区域时也起作用

我有2个Text里面的小部件GestureDetector. The onTap回调仅在我触摸时通知Text但不是我里面的空白空间Container。如何让这个通知就像我触摸按钮一样？

+------------------------------------------------+
| Very very very long long ◎ng long text view   |
| Short ◎xt                   ⦿                |
+------------------------------------------------+

• ◎：打印Tapped.
• ⦿：什么也没发生。

我的源代码:

ListView.separated(
  itemCount: _listModel.length,
  padding: EdgeInsets.only(left: NOTIFICATION_LEFT_SPACE),
  separatorBuilder: (context, index) => Divider(),
  itemBuilder: (BuildContext context, int index) => GestureDetector(
    child: Container(
      child: Hero(
        tag: _listModel[index].title,
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Text('Very very very long long long long text view'),
            SizedBox(height: 10),
            Text('Short text')
          ],
        ),
      ),
    ),
    onTap: () {
      print('Tapped');
    },
  ),
)

您可以使用behavior: HitTestBehavior.opaque的财产GestureDetector小部件，有助于点击内部的占位符Container即使Container小部件没有任何孩子。

GestureDetector(
                behavior: HitTestBehavior.opaque,
                child: Container(
                  child: Hero(
                    tag: 'test',
                    child: Column(
                      crossAxisAlignment: CrossAxisAlignment.start,
                      children: <Widget>[
                        Text('Very very very long long long long text view'),
                        SizedBox(height: 10),
                        Text('Short text')
                      ],
                    ),
                  ),
                ),
                onTap: () {
                  print('Tapped');
                },
              ),
