将长文本包装到容器中，导致 Flutter 溢出

Question

我正在为我的应用程序创建一个通知中心，它包含一些标题和正文的长字符串，它总是导致溢出，我尝试使用扩展小部件，以及以下堆栈溢出问题：问题 1 ,问题 2但我不能将它应用到我的代码中，现在它是这样的：

我从我的 firebase cloud firestore 获取文本，并使用列表视图输出文本。

该标题文字是这样的：“艾伦Indefenzo已取消同意您访问他/她的数据”
的正文是这样的：“他/她已经删除了所有的访问，您将不再能够查看/修改他的数据，再次访问要求用户再次向您提供他/她的特殊代码。”

这是我的代码：

Container(
        color: Colors.white,
        child: StreamBuilder(
          stream: db
              .collection('users')
              .document(userData.userID)
              .collection('notifications')
              .snapshots(),
          builder: (BuildContext context, AsyncSnapshot snapshot) {
            if (!snapshot.hasData) {
              return Center(
                child: CircularProgressIndicator(),
              );
            }
            if (snapshot.data.documents.length != 0) {
              return ListView.builder(
                itemCount: snapshot.data.documents.length,
                itemBuilder: (BuildContext context, int index) {
                  return Container(
                    child: Row(
                      children: <Widget>[
                        Container(
                          height: 150,
                          width: 100,
                          child: Image(
                            image: NetworkImage(
                                snapshot.data.documents[index]['dpURL']), fit: BoxFit.contain,
                          ),
                        ),
                        Column(
                          children: <Widget>[
                            Container(
                              height: 50,
                              width: MediaQuery.of(context).size.width * 0.8,
                              child:
                                  Text(snapshot.data.documents[index]['title']),
                            ),
                            Container(
                              height: 50,
                              width: MediaQuery.of(context).size.width * 0.8,
                              child:
                                  Text(snapshot.data.documents[index]['body']),
                            ),
                          ],
                        ),
                      ],
                    ),
                  );
                },
              );
            }
          },
        ),
      ),

任何帮助表示赞赏，如果你能解释它会很棒！非常感谢！

试着包裹你的Column内心Expanded，

 Container(
              child: Row(
                children: <Widget>[
                  Container(
                    height: 150,
                    width: 100,
                    child: Image(
                      image: NetworkImage(
                          'https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcQLBtBU3nUOK7osT41ZsQhP4VBV7fd9euqXvXVKQH0Q7bl4txeD'),
                      fit: BoxFit.contain,
                    ),
                  ),
                  Expanded(
                    child: Column(
                      children: <Widget>[
                        Text(
                            'Reallly looooooooooooooooooooooooooooooong textttttttttttttttttttttttttttttttttttttttttttttttt'),
                        Text(
                            'Reallly looooooooooooooooooooooooooooooong textttttttttttttttttttttttttttttttttttttttttttttttt'),
                      ],
                    ),
                  ),
                ],
              ),
            );

输出：

此外，如果您想限制Text使用线路，

  Text(
'Reallly looooooooooooooooooooooooooooooongtextttttttttttttttttttttttttttttttttttttttttttttttt',
    maxLines: 2,
    overflow: TextOverflow.ellipsis,
                        ),

输出：
