如何使用 "snapshot.data" Flutter 将文本连接到 "Text widget"

How can i concat text into "Text widget" with "snapshot.data" Flutter

我想在包含 snapshot.data 的文本小部件中连接文本,但我现在不能这样做。这是我的代码:

                               subtitle: Column(
                                  crossAxisAlignment: CrossAxisAlignment.start,
                                  children: <Widget>[
                                    Text(
                                      snapshot.data!.docChanges[index]
                                          .doc['entCourse'],
                                      style: TextStyle(
                                        fontSize: 13,
                                        color: Colors.grey,
                                      ),
                                    ),
                                    Text(
                                      // i think here would be the text to concat: 'Valoration is:'
                                      snapshot.data!.docChanges[index]
                                          .doc['valCourse'],
                                      style: TextStyle(
                                        fontSize: 8,
                                        color: Colors.yellowAccent,
                                      ),
                                    ),
                                  ],
                                ),

我想要的是这样的

您可以使用字符串插值并使其不带 + 运算符 像这样,

Text("this is sample text ${snapshot.data!.docChanges[index].doc["calCourse"]}"),
