颤振的本地通知发送带有有效负载选项的ID

Question

我有一个使用sqflite存储数据的应用程序。我使用构造函数方法从详细信息页面访问使用listview列出的记录。简短的代码如下。

notes.dart->主页

 child: ListView.builder(
                            itemCount: notes.length,
                            itemBuilder: (context, index) {
                              return NoteClass(
                                  notes: notes[index],
                                  );
                            },
                          ),

[在便笺详细信息页面上，我使用flutterLocalNotificationsPlugin.schedule设置了通知，我可以查看带有通知的便笺详细信息。但是，当我单击通知时，我想转到相关注释的详细信息页面。我发送了带有有效负载参数的记录ID。

---

然后，我在notes.dart中添加了onSelectNotification方法。

Future onSelectNotification(String payload) async {
    if (payload != null) {

######## what should I write here? ########

    }
  }

有效负载中有一个ID值。如何访问有关ID信息的注释详细信息。或单击通知，以这种方式我可以转到注释详细信息页面。

Answer 1

几乎您要做的就是与此类似的事情

class NoteDetail extends StatefulWidget {
  final String payload;
  NoteDetail (this.payload);

  @override
  State<StatefulWidget> createState() => NoteDetailState(payload);

}
class NoteDetailState extends State {
 Todo todo;
 TodoDetailState(this.todo);

 @override
 Widget build(BuildContext context) {
 return Scaffold(
  appBar: AppBar()
  body:Column( your column code here))
  }
// call this after something
void save() {
  //dosomething
  // go back to the old page 
  // notice the true, if all goes good with save send true otherwise false
  Navigator.pop(context, true);
}

}

// use this code to go to detail
void navigateToDetail(String payload) async {
bool result = await Navigator.push(context, 
    MaterialPageRoute(builder: (context) => NoteDetail(payload)),
);
if (result == true) {
  getData(); // refresh data from db
}

}
