In this file pubspec.yaml
fcm_shared_isolate:
path: ./packages/FcmSharedIsolate-update-master/
Base Of the Project URL: FCM Shared Isolate
Firebase Messaging Plugin for Flutter supporting shared isolate
After adding the library to your pubspec.yaml do the following things:
- Modify the main activity on the android side of your app to look like the following
(typically in
android/app/src/main/kotlin/your/app/id/MainActivity.kt):
package your.app.id
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import android.content.Context
import android.os.Bundle
import android.util.Log
import android.view.WindowManager
class MainActivity : FlutterActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
};
override fun provideFlutterEngine(context: Context): FlutterEngine? {
return provideEngine(this)
}
override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
// do nothing, because the engine was been configured in provideEngine
}
companion object {
var engine: FlutterEngine? = null
fun provideEngine(context: Context): FlutterEngine {
var eng = engine ?: FlutterEngine(context, emptyArray(), true, false)
engine = eng
return eng
}
}- Add an
FcmPushService(typically inandroid/app/src/main/kotlin/your/app/id/FcmPushService.kt)
package your.app.id
import com.famedly.fcm_shared_isolate.FcmSharedIsolateService
import your.app.id.MainActivity
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.view.FlutterMain
import io.flutter.embedding.engine.dart.DartExecutor.DartEntrypoint
import android.content.Context
import android.os.Bundle
import android.util.Log
import android.view.WindowManager
class FcmPushService : FcmSharedIsolateService() {
override fun getEngine(): FlutterEngine {
return provideEngine(getApplicationContext())
}
companion object {
fun provideEngine(context: Context): FlutterEngine {
var engine = MainActivity.engine
if (engine == null) {
engine = MainActivity.provideEngine(context)
engine.getLocalizationPlugin().sendLocalesToFlutter(
context.getResources().getConfiguration())
engine.getDartExecutor().executeDartEntrypoint(
DartEntrypoint.createDefault())
}
return engine
}
}
}
- Add the intent filters to your
AndroidManifest.xml(typically inandroid/app/src/main/AndroidManifest.xml):
<service android:name=".FcmPushService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>Note that the .FcmPushService has to match the class name defined in the file above
// Create the instance
final fcm = FcmSharedIsolate();
// Only for iOS you need to request permissions:
if (Platform.isIOS) {
await fcm.requestPermission();
}
// Get the push token:
await fcm.getToken();
// Set the listeners
fcm.setListeners(
onMessage: onMessage,
onNewToken: onNewToken,
);
Future<void> onMessage(Map<dynamic, dynamic> message) async {
print('Got a new message from firebase cloud messaging: $message');
