Making class public solved the problem for me.

The error is telling you that Android can't find the service you declared with the the full class name "com.samriddh.partner.java.MyFirebaseMessagingService". Either you never added this class, or you told Android the wrong name in the manifest.

It sounds like you didn't complete the documented instructions to integration FCM into your app. – Doug Stevenson Sep 21 '20 at 06:09

Check if the package on the top is the correct. ex.

package com.samriddh.partner

If you copy/paste (like dummy me) from an example, it has some other package.

package com.google.firebase.quickstart.fcm.kotlin

At the time of writing I am using flutter firebase_messaging package v14.2.3. and I need this in order to recieve FCM messages in direct boot mode (while app is not started).

I have opened the project in Android Studio and looked for the FlutterFirebaseMessagingService class in imported packages.

The fix that worked for me was using this class name io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingService in android/app/src/main/AndroidManifest.xml:

        <service
            android:name="io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>
