[marcoberetta96]

Yes, initially created with flutter 1.

[shiyiya]

try migrate to flutter 2.

[marcoberetta96]

@shiyiya what do you mean? I'm already on flutter 2.8.1

[shiyiya]

Can you post the MainActivity.kt file?
flutter 1 and 2 are not the same.
are u upgrade it？

[marcoberetta96]

Here my MainActivity.java. Am I missing something?

package com.marco...;

import android.content.Context;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Handler;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.style.ForegroundColorSpan;
import android.util.Log;
import androidx.annotation.NonNull;
import com.onesignal.OSMutableNotification;

import com.onesignal.OSNotificationReceivedEvent;
import com.onesignal.OneSignal.OSRemoteNotificationReceivedHandler;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;
import java.math.BigInteger;
import java.util.HashMap;
import java.util.Map;
import org.json.JSONObject;

public class MainActivity extends FlutterActivity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
    }
}

Take a look at the official Flutter wiki:

[marcoberetta96]

Done, but issue is still the same. It happens only with this package.

/.../android/app/src/main/java/io/flutter/plugins/GeneratedPluginRegistrant.java:24: error: package com.jhomlala.better_player does not exist
      flutterEngine.getPlugins().add(new com.jhomlala.better_player.BetterPlayerPlugin());
                                                                   ^

[shiyiya]

😕 i have not idea.

[marcoberetta96]

Still debugging...
Everything works with better_player: 0.0.77
Issue comes with better_player: 0.0.78

From the changelog I see

• Migrated android native code to Kotlin.
• Updated ExoPlayer version to 2.15.1.

Maybe the cause is related to one of these...
@jhomlala do you have any idea?
