颤振–连续两个文本，左边一个优美地溢出 [英] Flutter – two text in a row with left one overflowing gracefully

问题描述

如何获取两个并排的文本小部件，以仅允许最左边的一个小部件正常溢出?

How do I get two side-by-side Text widgets to only allow the left-most one to overflow gracefully?

一列中的一个文本小部件很容易优雅地溢出. 并排放置两个文本小部件是有问题的.

One text widget in a column is easy to overflow gracefully. Two text widgets side-by-side in a row is problematic.

堆栈溢出需要更多详细信息，但老实说，这时我可能只是在浪费更多时间.

Stack overflow wants more details but honestly, I'm probably just wasting more of your time at this point.

Widget _listItem({String title, String subtitle}){
  return Row(
    children: <Widget>[
      _listItemIcon(),
      Expanded(
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            _listItemTitle(title),
            Row(
              children: <Widget>[
                _listItemSubtitle(subtitle), // how do I allow this to overflow gracefully
                _listItemTime("2m") // but stop this from overflowing
              ],
            )
          ],
        ),
      ),
      _listItemFavorite()
    ],
  );
}

//////////////
Widget _listItemIcon(){
  return Icon(Icons.message);
}

Widget _listItemTitle(String title){
  return Text(
    title,
    softWrap: false,
    overflow: TextOverflow.fade,
    style: TextStyle(
      fontSize:24.0
    ),
  );
}

Widget _listItemSubtitle(String subtitle){
  return Text(
    "[$subtitle]",
    softWrap: false,
    overflow: TextOverflow.fade,
    );
}

Widget _listItemTime(String time){
  return Text(
    "[$time]",
    softWrap: false,
    overflow: TextOverflow.fade,
    );
}

Widget _listItemFavorite(){
  return Icon(Icons.favorite);
}

推荐答案

您可以使用Flexible小部件:

Widget _listItemSubtitle(String subtitle) {
  return new Flexible(
    fit: FlexFit.loose,
    child: Text(
      "[$subtitle]",
      softWrap: false,
      overflow: TextOverflow.fade,
    ),
  );
}

替代:

如果您希望时间小部件始终位于右侧，则可以将字幕文本包装在Expanded小部件中:

If you prefer that the time widget is always on the right, you could wrap the subtitle text in an Expanded widget:

Widget _listItemSubtitle(String subtitle){
  return Expanded(
    child: Text(
      "[$subtitle]",
      softWrap: false,
      overflow: TextOverflow.fade,
    ),
  );
}
