java.lang.RuntimeException: Unable to create service io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService - node.js

Question

I am using Firebase Cloud Messaging for push notifications in a Flutter app using node.js + Typescript.
The FCM configurations for onLaunch and onResume were working fine, until I added Firebase dynamic links. Now, every time I receive a notification, the app crashes.
I have included click_action: 'FLUTTER_NOTIFICATION_CLICK' in the notification payload as well.
I do not have an Application.java file, I am using Flutter Android Embedding V2 (Flutter Version >= 1.12) and hence, no additional integration steps are required for Android.

Answer 1

Create a separated file beside MainActivity.kt and name it Application.kt and type the following code inside it.
//Don't forget to change it to your app package name!!!
package com.your.packagename
import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
import io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService.setPluginRegistrant
class Application : FlutterApplication(), PluginRegistrantCallback {
override fun onCreate() {
super.onCreate()
setPluginRegistrant(this)
}
override fun registerWith(registry: PluginRegistry?) {
FirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
}
}
Then, on your AndroidMainfest.xml add android:name=".Application" to your application tag
<application
...
android:name=".Application"
>
Finally, add firebase-messaging to your app/build.gradle.
dependencies {
...
implementation "com.google.firebase:firebase-messaging:20.1.0"
}
