我有一个问题，我的文本溢出右侧的卡片，但我尝试应用Expanded\ Flexible，我尝试使用FittedBox但fit: BoxFit.scaleDown没有用，所以要么我将它们放在错误的祖先顺序中，要么是其他问题。Container最初，应该是高度，98但由于文本很长，我想保留设计，但高度可以动态更改而不是固定，因为我想将文本放入Card小部件中。

这是代码：

Card(
                                          color: Color(0xFF29ABE2),
                                          elevation: 4,
                                          shape: RoundedRectangleBorder(
                                            borderRadius:
                                                BorderRadius.circular(4),
                                          ),

                                          ),
                                        ),

我已经从小部件中删除了样式属性，因此可以更轻松地查看代码。在此先感谢您的帮助！

我添加了一个 Expanded to Column 以使其尽可能多地填充空间。

为了使高度根据文本动态变化，我删除了 Container 的固定高度，并在 Column 中添加了属性“mainAxisSize: MainAxisSize.min”，以尽可能少地填充空间。

最后，我调整了填充，为了让文本之间有间距，我在它们之间使用了 Sizedbox。

...

Container(
            width: MediaQuery.of(context).size.width,
            decoration: BoxDecoration(
                color: Colors.white,
                borderRadius: BorderRadius.only(
                    bottomRight: Radius.circular(4),
                    topRight: Radius.circular(4))),
            margin: EdgeInsets.only(left: 3),
            padding: EdgeInsets.symmetric(vertical: 16.0, horizontal: 16.0),
            child: Row(
              children: [
                Expanded(
                  child: Column(
                    mainAxisSize: MainAxisSize.min,
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: [
                      Text('7/22/2021 14:59'),
                      SizedBox(height: 8.0),
                      Text(
                        'New York, NY, USA - 1 World Way, Los Angeles, CA 90045, USA',

                      SizedBox(height: 8.0),

将 a 添加Flexible到您的所有小部件中Row

更改flex值以调整每个项目的大小。

...

Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: [
        Flexible(
          flex: 3,
          child: Padding(
            padding: const EdgeInsets.only(left: 16.0),
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: [
                Text('7/22/2021 14:59'),
                Text(
                    'New York, NY, USA - 1 World Way, Los Angeles, CA 90045, USA',
                    overflow: TextOverflow.clip),
                Text('7/22/2021 14:59'),
              ],
            ),
          ),
        ),
        Flexible(
          flex: 1,
          child: Padding(
            padding: const EdgeInsets.only(right: 22.0),

您应该使用灵活或扩展的小部件，如下代码：

            Card(
              color: Color(0xFF29ABE2),
              elevation: 4,
              shape: RoundedRectangleBorder(
                borderRadius: BorderRadius.circular(4),
              ),
              child: Wrap(
                children: [
                  Container(
                    height: 98,
                    width: MediaQuery.of(context).size.width,
                    decoration: BoxDecoration(
                      color: Colors.white,
                      borderRadius: BorderRadius.only(
                        bottomRight: Radius.circular(4),
                        topRight: Radius.circular(4),
                      ),
                    ),

                                    'New York, NY, USA - 1 World Way, Los Angeles, CA 90045, USA'),
                                Text('7/22/2021 14:59'),
