Setup Android

  2. Uncomment or remove Expo’s FCM listener from android/app/src/AndroidManifest.xml:

    <!-- FCM -->
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>

  3. Add our FCM listeners to android/app/src/AndroidManifest.xml:

    <application ...>
               <action android:name="com.google.firebase.MESSAGING_EVENT" />
               <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />


import 'package:cleverpush_flutter/cleverpush_flutter.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => new _MyAppState();

class _MyAppState extends State<MyApp> {
  String _debugLabelString = "";

  void initState() {

  Future<void> initPlatformState() async {
    if (!mounted) return;

    CleverPush.shared.setNotificationReceivedHandler((CPNotification notification) {
      print("Notification received: \n${notification.jsonRepresentation()}");

    CleverPush.shared.setNotificationOpenedHandler((CPNotificationOpenedResult result) {
      print("Notification opened: \n${notification.jsonRepresentation()}");

    CleverPush.shared.setSubscribedHandler((subscriptionId) {
      print("Subscribed: ${subscriptionId}");

    await CleverPush.shared.init("INSERT_CLEVERPUSH_CHANNEL_ID_HERE");

CleverPush.shared.isSubscribed().then((status) {
