[英]How can i concat text into "Text widget" with "snapshot.data" Flutter
I want to concat text inside a Text widget that contains an snapshot.data, but i couldn't do that for now.我想在包含 snapshot.data 的 Text 小部件中连接文本,但我现在不能这样做。 This is my code:
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,
),
),
],
),
what i want is something like this我想要的是这样的
You can use string interpolation and make it without + operator something like this,您可以使用字符串插值并使其不使用 + 运算符,如下所示,
Text("this is sample text ${snapshot.data!.docChanges[index].doc["calCourse"]}"),
