    you have to mentioned your channel_id and channel_name if you want to push notification service.

    Changes in AndroidManiFest.xml

     <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <!-- added for firebase push notification configuration  -->
            <action android:name="FLUTTER_NOTIFICATION_CLICK" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id"
        android:value="high_importance_channel" />
    <!-- Don't delete the meta-data below.

    <meta-data
        android:name="flutterEmbedding"
        android:value="2" />
