ListTile中的图像

Question

如何向列表中添加高度等于列表的全高、宽度等于列表的宽度(例如200 )的照片？

    Card(
      child: ListTile(
        leading: ConstrainedBox(
            constraints: BoxConstraints(
             minWidth: 80,
             minHeight: 80,
             ),
        child: Image.network('https://d-pt.ppstatic.pl/k/r/1/59/d4/5cb1dbc30ec6d_p.jpg?1555262447', width: 120, height: 120),),
        title: Text('Three-line ListTile'),
        subtitle: Text(
          'A sufficiently long subtitle warrants three lines.'
        ),
        trailing: Icon(Icons.more_vert),
        isThreeLine: true,
      ),
    ),

Answer 1

你可以这样做：

Card(
    child: Row(
      children: <Widget>[
        Expanded(
          flex: 1,
          child: Image.network(
            'https://d-pt.ppstatic.pl/k/r/1/59/d4/5cb1dbc30ec6d_p.jpg?1555262447',
          ),
        ),
        Expanded(
          flex: 2,
          child: ListTile(
            title: Text('Three-line ListTile'),
            subtitle:
                Text('A sufficiently long subtitle warrants three lines.'),
            trailing: Icon(Icons.more_vert),
            isThreeLine: true,
          ),
        ),
      ],
    ),
  ),

然后根据flex属性调整图像的大小。
