Flutter: Clip a Column or Row to prevent overflow

Wrap widget solves your problem. If there is not enough space to fit the child in a Column or Row, you can use Wrap. You can use alignment, directionality and spacing properties to customize it.

Here is the simple example:

class WrapExample extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return SizedBox(
      width: 200,
      height: 180,
      child: Card(
        clipBehavior: Clip.antiAlias,
        child: Wrap(
          direction: Axis.horizontal,
          spacing: 8.0, // gap between adjacent chips
          runSpacing: 4.0, // gap between lines
          children: <Widget>[
            Chip(
              avatar: CircleAvatar(
                  backgroundColor: Colors.blue.shade900, child: Text('AH')),
              label: Text('Hamilton'),
            ),
            Chip(
              avatar: CircleAvatar(
                  backgroundColor: Colors.blue.shade900, child: Text('ML')),
              label: Text('Lafayette'),
            ),
            Chip(
              avatar: CircleAvatar(
                  backgroundColor: Colors.blue.shade900, child: Text('HM')),
              label: Text('Mulligan'),
            ),
            Chip(
              avatar: CircleAvatar(
                  backgroundColor: Colors.blue.shade900, child: Text('JL')),
              label: Text('Laurens'),
            ),
          ],
        ),
      ),
    );
  }
}

And here is the output:
