Flutter Container Dynamic Height

问题

我有一个应用程序,我在其中显示我的笔记。
在左侧,我显示用户选择的颜色,高度为200,具体高度取决于文本大小。如何根据文本大小调整颜色线的高度?


return Container(
    margin: const EdgeInsets.all(8.0),
    decoration: BoxDecoration(),
    child: InkWell(
      onTap: () {},
      onLongPress: () {},
      child: Row(
        mainAxisAlignment: MainAxisAlignment.start,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Container(
            width: 8.0,
            height: 200.0,
            decoration: BoxDecoration(
                color: Color((int.parse('0x${list[idx].color}')),
                borderRadius: const BorderRadius.only(
                    bottomLeft: Radius.circular(12.0),
                    topLeft: Radius.circular(12.0))),
          ),
           Flexible(
            child: Container(
              margin: const EdgeInsets.all(12.0),
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text(
                    '标题',
                    style: TextStyle(
                        fontSize: 18.0,
                        fontWeight: FontWeight.w500),
                  ),
                  const SizedBox(height: 6.0),
                  Text(
                    '不,你误解了。最大字符数为150。容器的高度会根据可变文本大小而更改。这是正常的。不同文本大小不会更改左侧的线长度。',
                    style: TextStyle(
                        fontSize: 16.0),
                  ),
                ],
              ),
            ),
          ),
        ],
      ),
    ),
  );

I have an app where I show my notes.
On the left, I show the colors selected by the user with a height of 200 depending on the text size. How can I adjust the height of the color line depending on the text size?

                  Text(
                    &#39;No, you misunderstood. The maximum number of characters is 150. Container height changes according to variable text size. That&#39;s fine here. What doesn&#39;t change with different text size is the line length on the left side.

  &#39;
                    style: TextStyle(
                        fontSize: 16.0),
                  ),
                ],
              ),
            ),
          ),
        ],
      ),

This is what you need actually:

IntrinsicHeight

    SafeArea(
            child: Scaffold(
              body: Column(
                children: [
                  SizedBox(
                    height: 100,
                  ),
                  Padding(
                    padding: const EdgeInsets.all(20.0),
