flutter - 如何使我的内容具有响应性并且不会溢出容器

Question

这是我的容器在模拟器 (Pixel 3) 上的样子:

现在这就是它在我的 Galaxy S9 上的样子:

我专栏的文字溢出来了。我以为它会自动“适应”，但似乎并非如此。

溢出的4个元素的代码是:

                          child: Row(
                            mainAxisAlignment: MainAxisAlignment.spaceBetween,
                            children: <Widget>[
                              Column(
                                crossAxisAlignment: CrossAxisAlignment.start,
                                children: <Widget>[
                                  Row(
                                    //mainAxisAlignment: MainAxisAlignment.start,
                                    children: <Widget>[
                                      Icon(
                                        Icons.turned_in_not,

                                      SizedBox(width: 7.0,),

                          ),                          

知道我应该更改什么以使文本不会溢出其容器吗？

谢谢。

Answer 1

我建议用 Expanded 小部件包装溢出的小部件。希望对您有所帮助。

更新 我只是在一些具有 mdpi 分辨率的旧设备上使用了上面的代码。为了修复溢出，我在第二个 Column 中添加了 Expanded，它解决了溢出问题，但“Standard legroom”文本仍然溢出。因此，如果字符串非常长，我建议为您的文本添加 overflow: TextOverflow.ellipsis。

如果您想保留整个字符串，只需将 Expanded 添加到溢出的 Text 小部件。但这种情况下会出现多行文字，无法解决。

无论如何，这是我的最终代码:

    Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: <Widget>[
        Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Row(
              //mainAxisAlignment: MainAxisAlignment.start,
              children: <Widget>[
                Icon(
                  Icons.turned_in_not,
                  color: Colors.grey[700],
                  size: 18.0,
                ),
                SizedBox(
                  width: 7.0,
                ),
                Text(
                  'Economy',
                  style: TextStyle(
