Flutter Flexible 不在列内换行文本

Question

我正在尝试制作一个可能有一些长文本的小部件，我想用几行换行。
我正在尝试使用“ Flexible ”小部件来包装我的 Text但它仍然溢出，我不知道出了什么问题。
这是正在发生的事情:
这是我的 Column 代码与 Text 相关的 s :

Container(
  child: Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: [
      Text(
        'My Title text',
        style: TextStyle(
            fontWeight: FontWeight.bold,
            fontSize: 18.0,
            color: Colors.black),
      ),
      Text(
        'This is lower text',
        style: TextStyle(
            fontWeight: FontWeight.w200,
            fontSize: 16.0,
            color: Colors.black),
      ),
      Flexible(
        child: Text(
          'Here is some long text that I am expecting will go off of the screen.',
          style: TextStyle(
              fontWeight: FontWeight.normal,
              fontSize: 16.0,
              color: Colors.black),
        ),
      )
    ],
  ),
),

如果相关，这里是整个小部件:

Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Material(
        color: Colors.transparent,
        child: Container(
          height: 100.0,
          child: Padding(
            padding: EdgeInsets.all(8.0),
            child: Row(
              crossAxisAlignment: CrossAxisAlignment.stretch,
              children: [
                Padding(
                  padding: EdgeInsets.all(16.0),
                  child: Icon(
                    Icons.cake,
                    size: 60.0,
                  ),
                ),
                Container(
                  child: Column(
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: [
                      Text(
                        'My Title text',
                        style: TextStyle(
                            fontWeight: FontWeight.bold,
                            fontSize: 18.0,
                            color: Colors.black),
                      ),
                      Text(
                        'This is lower text',
                        style: TextStyle(
                            fontWeight: FontWeight.w200,
                            fontSize: 16.0,
                            color: Colors.black),
                      ),
                      Flexible(
                        child: Text(
                          'Here is some long text that I am expecting will go off of the screen.',
                          style: TextStyle(
                              fontWeight: FontWeight.normal,
                              fontSize: 16.0,
                              color: Colors.black),
                        ),
                      )
                    ],
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }

您可以在此处使用扩展。 展开 ，这会迫使 child 扩展以填充可用空间。您可以在此处展开​​列。

这是列的代码片段:-

Expanded(
                  child: Container(
                    child: Column(
                      crossAxisAlignment: CrossAxisAlignment.start,
                      children: [
                        Text(
                          'My Title text',
                          style: TextStyle(
                              fontWeight: FontWeight.bold,
                              fontSize: 18.0,
                              color: Colors.black),
                        ),
                        Text(
                          'This is lower text',
                          style: TextStyle(
                              fontWeight: FontWeight.w200,
                              fontSize: 16.0,
                              color: Colors.black),
                        ),
                        Flexible(
                          child: Text(
                            'Here is some long text that I am expecting will go off of the screen.',
                            style: TextStyle(
                                fontWeight: FontWeight.normal,
                                fontSize: 16.0,
                                color: Colors.black),
                          ),
                        )
                      ],
                    ),
                  ),
                )

这是您的期望:-


希望它会起作用。
