how to implement click action in firebase push notifications both foreground and background in flutter?

Question

I have a problem that I have not been able to solve yet It happens that I need to use the click action of the firebase push notifications both in the foreground and in the background

in the foreground I used the flutter_local_notifications library and everything worked fine

_firebaseMessaging.configure(
    onMessage: (Map<String, dynamic> message) async {
        ///HERE SHOW THE NOTIFICATION IN THE NOTIFICATION CENTER WITH flutter_local_notifications
        _showNotification(message);
    },
    onBackgroundMessage: myBackgroundMessageHandler,
    onLaunch: (Map<String, dynamic> message) async {
        _openScreen(message);
    },
    onResume: (Map<String, dynamic> message) async {
        _openScreen(message);
    },
    );

but in the background I couldn't use the "onBackgroundMessage" so searching in forums I found that I needed to register the plugin from kotlin and I did it this way:

File Application.kt

class Application : FlutterApplication(), PluginRegistrantCallback {

    override fun onCreate() {
        super.onCreate()
        FlutterFirebaseMessagingService.setPluginRegistrant(this);
        FlutterMain.startInitialization(this)
    }

    override fun registerWith(registry: PluginRegistry?) {
        if (!registry!!.hasPlugin("io.flutter.plugins.firebasemessaging")) {
            FirebaseMessagingPlugin.registerWith(registry!!.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
        }
    }
}

File MainActivity.kt

class MainActivity: FlutterActivity() {
}

File AndroidManifest.xml

<application
        android:name=".Name"
        android:label="Negocio TinBin"
        android:icon="@mipmap/launcher_icon">

<activity
            android:name=".MainActivity">

    <intent-filter>
                <action android:name="FLUTTER_NOTIFICATION_CLICK" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>

</activity>

</application>

With this change it works without problems in the background and when you click if the "myBackgroundMessageHandler" function is executed, but it stopped working in the foreground, I check the log and not even go through "onMessage" of the firebase configuration Anyone have any idea what I could do to make it work both in the foreground and in the background?

Solution

You have to specify the click_action inside your js script, in which you have written the cloud functions, without specifying it, you would not be able to get onResume() and onLaunch() callbacks.

"data": {"click_action": "FLUTTER_NOTIFICATION_CLICK",  }

Make sure have this line of code in your Manifests.xml file.

<intent-filter>
      <action android:name="FLUTTER_NOTIFICATION_CLICK" />
      <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>

After hours looking for a solution, I decided to try to create a new project with the same code, it turns out that now if everything worked correctly, the only thing that occurs to me is that the initial flutter configurations had a problem with the version, and when creating a new project was solved
