如果我理解你的问题，这并不容易，我相信这就是你想要做的：

class UI62962286 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Column(
      children: <Widget>[
        Expanded(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: <Widget>[
              Container(
                child: Icon(Icons.accessibility),
                height: 10,
              ),
              Container(
                child: Icon(Icons.account_balance),
                height: 10,
              ),
            ],
          )
        ),
        Container(
          padding: EdgeInsets.all(8.0),
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceAround,
            children: <Widget>[
              Icon(Icons.account_balance_wallet),
              Icon(Icons.adb),
              Icon(Icons.account_box),
              Icon(Icons.ac_unit),
            ],
          ),
        ),
      ],
    );
  }
}

它看起来像这样：

Try this in the Widget:

 body: Center(
        child: Column(
          children: <Widget>[
            Text(
              'Start Row',
            ),
            Expanded(child:
              Center(child:Text('Middle Row')),
            ),
            Text('End Row'),
          ],
        ),
      ),

Where you see the text you want to insert a Row. Expand takes all the space in the middle no matter how big your screen. You can cascade that design idea.
