    await _localNotificationService.show(id, title, body, details);
  }

  void _onDidReceiveLocalNotification(
      int id,String? title,String? body,String? payload) {
    print('id $id');
  }

  void onSelectNotification(
      String? payload) {
    print('payload $payload');
  }

}

screen 2:

onPressed: () async {await service.showNotification(id: 0, title: 'title', body: 'body');

CodePudding user response：

It may be because of wrong(unextisted) notification icon. Check it and maybe use it from another folder.

I think you already added this line to your code, but I have to mention(Use it when the app starts):

WidgetsFlutterBinding.ensureInitialized();

Also, have you added this to your manifest?

<receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />
    <receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
            <action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>
        </intent-filter>
    </receiver>
