flutter - Flutter-mainAxisAlignment对列中的行不起作用

Question

我对Row和Column小部件很熟悉。但是我在'float'中以父Row的正确大小对Row的内容进行尝试尝试Column时遇到了麻烦，但无法正常工作

Row(
  //      mainAxisSize: MainAxisSize.min,
  mainAxisAlignment:
      isMine ? MainAxisAlignment.end : MainAxisAlignment.start,
  children: <Widget>[
    Container(
      margin: isMine
          ? EdgeInsets.only(right: 10.0, bottom: 20.0)
          : EdgeInsets.only(
              left: 10.0,
              bottom: 20.0,
            ),
      constraints: BoxConstraints(maxWidth: deviceSize.width * 0.85),
      decoration: BoxDecoration(
          color: isMine ? Colors.green[200] : Colors.grey[300],
          borderRadius: BorderRadius.circular(10.0)),
      padding: EdgeInsets.symmetric(vertical: 10.0, horizontal: 10.0),
      child: Column(
        mainAxisAlignment: MainAxisAlignment.end,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: <Widget>[
          Text(message),
          Row(
            // Horizontally
            mainAxisAlignment: MainAxisAlignment.end,
            // Vertically
            crossAxisAlignment: CrossAxisAlignment.center,
            mainAxisSize: MainAxisSize.min,
            children: <Widget>[
              Text(sentAtToSting(sentAt)),
              SizedBox(width: 10.0),
              Icon(Icons.done_all)
            ],
          ),
        ],
      ),
    ),
  ],
);

那么有人可以帮助我将包含时间和图标的 Row移动到突出显示区域的右侧吗？
我将非常感谢您的帮助!
谢谢 !

Answer 1

这是因为您使用

mainAxisSize: MainAxisSize.min

尝试移除主轴尺寸并查看
