flutter 通知,适用安卓ios

最近在开发xmpp及时通讯,通知是必不可少的,记录下自己的成果

1 首先引入包

  cupertino_icons: ^0.1.3
  http: ^0.12.0+2
  path_provider: ^1.3.1
  shared_preferences: ^0.5.4
  rxdart: ^0.20.0
  flutter_local_notifications: ^0.8.0

2 主代码入下,自己需要修改下使用

final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
    FlutterLocalNotificationsPlugin();

// Streams are created so that app can respond to notification-related events since the plugin is initialised in the `main` function
final BehaviorSubject<ReceivedNotification> didReceiveLocalNotificationSubject =
    BehaviorSubject<ReceivedNotification>();

final BehaviorSubject<String> selectNotificationSubject =
    BehaviorSubject<String>();

class ReceivedNotification {
  final int id;
  final String title;
  final String body;
  final String payload;

  ReceivedNotification(
      {@required this.id,
      @required this.title,
      @required this.body,
      @required this.payload});
}

/// IMPORTANT: running the following code on its own won't work as there is setup required for each platform head project.
/// Please download the complete example app from the GitHub repository where all the setup has been done
Future<void> main() async {
  // needed if you intend to initialize in the `main` function
  WidgetsFlutterBinding.ensureInitialized();
  // NOTE: if you want to find out if the app was launched via notification then you could use the following call and then do something like
  // change the default route of the app
  // var notificationAppLaunchDetails =
  //     await flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails();
