Flutter RenderFlex在Column Widget内部右侧溢出了15个像素 [英] Flutter RenderFlex overflowed by 15 pixels on the right inside Column Widget

问题描述

我创建了一个自定义ListTile，该列表应在中间居中放置两个分数，并在其左右两侧提供信息(屏幕截图).

I created a custom ListTile which should have two score centered in the middle and information on the left and right of this (screenshot).

左侧的信息可以具有任意长度，如果长度太长，则应使用TextOverflow.ellipsis.我无法使它正常工作，因为文本似乎不知道它应该具有的宽度并且溢出.我尝试将文本小部件包装到SizedBox，Expanded等中.这没有用.

The information on the left can have arbitrary length and should use TextOverflow.ellipsis when it's too long. I cannot get this to work since the Text does not seem to know the width it is supposed to have and overflows. I have tried wrapping the Text widgets into SizedBox, Expanded, etc. This has not worked.

    flutter: ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
    flutter: The following message was thrown during layout:
    flutter: A RenderFlex overflowed by 15 pixels on the right.
    flutter:
    flutter: The overflowing RenderFlex has an orientation of Axis.horizontal.
    flutter: The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
    flutter: black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
    flutter: Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
    flutter: RenderFlex to fit within the available space instead of being sized to their natural size.
    flutter: This is considered an error condition because it indicates that there is content that cannot be
    flutter: seen. If the content is legitimately bigger than the available space, consider clipping it with a
    flutter: ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
    flutter: like a ListView.
    flutter: The specific RenderFlex in question is:

我的代码如下:

@immutable
class GameTile extends StatelessWidget {
  final Game game;
  Color highligtColor = Colors.red;

  GameTile({this.game});

  @override
  Widget build(BuildContext context) {
    return InkWell(
      child: Container(
        height: 70.0,
        child: Column(
          children: <Widget>[
            Row(
              children: <Widget>[
                Expanded(
                  child: Row(
                    children: <Widget>[
                      Container(
                        width: 8.0,
                        height: 70.0,
                        color: highligtColor,
                      ),
                      Padding(
                        padding: EdgeInsets.only(left: 15.0),
                        child: Column(
                          crossAxisAlignment: CrossAxisAlignment.start,
                          children: <Widget>[
                            Text(
                              game.awayTeam.name,
                              overflow: TextOverflow.ellipsis,
                            ),
                            Text(
                              game.homeTeam.name,

                          ],
                        ),
                      ),
                    ],
                  ),
                ),
                Padding(
                  padding: const EdgeInsets.only(left: 8.0, right: 8.0),
                  child: Column(
                    children: [
                      Text(

                      )
                    ],
                  ),
                )
              ],
            )
          ],
        ),
      ),
    );
  }
}

推荐答案

只需用 Flexible

new Row(
          mainAxisAlignment: MainAxisAlignment.start,
          children: <Widget>[
            new Checkbox(
              onChanged: (bool){},
            ),
            Flexible(
              child: new Text(
                "This text can be so loooooooooooooong",
              ),
            ),

          ],
        ),
