dart - Flutter:右溢出 200 像素

Question

我正在我的 Flutter 应用程序中测试芯片。我已经在 Row 中添加了这些筹码。

但是当没有。筹码增加，应用显示黄条提示

Right Overflowed by 200 pixels

我只想显示适合第一排的那些筹码，所有剩余的筹码都​​应该显示在它的下方。

我的片段:

class ChipsTesting extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      body: new Padding(
        padding: new EdgeInsets.all(30.0),
        child: new Row(
          children: <Widget>[
            new Chip(
                label: new Text('Chips11')
            ),new Chip(
                label: new Text('Chips12')
            ),new Chip(
                label: new Text('Chips13')
            ),new Chip(
                label: new Text('Chips14')
            ),new Chip(
                label: new Text('Chips15')
            ),new Chip(
                label: new Text('Chips16')
            )
          ],
        ),
      ),
    );
  }
}

如果通过

All remaining chips should get displayed below to it

您的意思是当行上没有剩余空间时芯片应该换行，那么您应该使用 Wrap 小部件 (Documentation) 而不是 Row。它会自动在多个水平或垂直运行中显示其子项:

new Wrap(
  spacing: 8.0, // gap between adjacent chips
  runSpacing: 4.0, // gap between lines
  direction: Axis.horizontal, // main axis (rows or columns)
  children: <Widget>[
    new Chip(
      label: new Text('Chips11')
    ),new Chip(
      label: new Text('Chips12')
    ),new Chip(
      label: new Text('Chips13')
    ),new Chip(
      label: new Text('Chips14')
    ),new Chip(
      label: new Text('Chips15')
    ),new Chip(
      label: new Text('Chips16')
    )
  ],
)
