在嵌套的窗口小部件中颤动地包装文本

Question

我的Text小部件未包装，导致溢出。 I've tried methods from this post，但似乎缺少添加flex / expand的正确位置。

说"//get this text to wrap"的地方是我想包装的Text小部件。

Padding(
    padding: const EdgeInsets.only(top: 8.0),
    child: Text(snapshot.data[index].message_text, //get this text to wrap
        style: TextStyle(
          color: Colors.grey,
          fontSize: 15.0,
          fontWeight: FontWeight.bold,
        ),
      overflow: TextOverflow.visible,
    ),
  ),
