dart - 如何在 flutter 中自动调整行内文本的大小

Question

我正在尝试复制以下 UI。我想显示一个项目列表，其中每个项目平均分配到 3 个部分(参见下图)。我想达到同样的响应能力。但我不能把它们整理得井井有条。这是模型:

这是我取得的成就:

这是我的代码:

Card stockList() {
    return Card(
      child: Container(
        padding: EdgeInsets.all(16.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Text('Stocks & Values', style: Theme.of(context).textTheme.subtitle,),
            SizedBox(height: 10.0),
            tile1(),
            SizedBox(height: 10.0,),
            Divider(),
            SizedBox(height: 10.0,),
            tile2(),
            SizedBox(height: 10.0,),
            Divider(),
            tile3(),
            SizedBox(height: 10.0,),
            Divider(),
            tile4(),
          ],
        ),
      ),
    );
  }

  Container tile1() {
    return Container(
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,

            children: <Widget>[
              Text('35.00', style: Theme.of(context).textTheme.title,),
              SizedBox(height: 2.0,),
              Text('gms', style: Theme.of(context).textTheme.caption,)
            ],
          ),
          Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('$currencySymbol 34,355.00', style: Theme.of(context).textTheme.title,),
              SizedBox(height: 2.0,),
              Text('current value', style: Theme.of(context).textTheme.caption,)
            ],
          )
        ],
      ),
    );
  }

我哪里出错了？关于如何使此布局具有响应性以使其保持对齐的任何想法，如模型中所示。

Answer 1

为了让一组 child 在彼此之间占据相同的空间，将他们包裹在 Expanded 中:

Container tile1() {
  return Container(
    child: Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: <Widget>[
        Expanded(
          // Your column
        ),
        Expanded(
          // Your column
        ),
        Expanded(
          // Your column
        )
      ],
    ),
  );
}
