Android Widget onReceive not Triggered by Button Clicks

Question

I am facing an issue with my Android widget. The onReceive method is automatically triggered when the widget is placed on the home screen, but it doesn't get called when I click the buttons with ids (button1, button2) or the ImageView with the ID @+id/imageRightOfButtons.

I have set up PendingIntent with setOnClickPendingIntent for 2 butttons and imageview in the onUpdate method, but the onReceive method is not getting invoked.

NewAppWidget.java

public class NewAppWidget extends AppWidgetProvider {
    public static final String ACTION_BUTTON1_CLICK = "com.yourapp.ACTION_BUTTON1_CLICK";
    public static final String ACTION_BUTTON2_CLICK = "com.yourapp.ACTION_BUTTON2_CLICK";
    private final Long callBackDispatcherId=4944696197L;
    FlutterEngine backgroundFlutterEngine;
    DartExecutor executor;
    BinaryMessenger binaryMessenger;
    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        Log.d("NewAPPWidget", "latest onUpdate method");
        for (int appWidgetId : appWidgetIds) {
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
            Intent button1Intent = new Intent(context, NewAppWidget.class);
            button1Intent.setAction(ACTION_BUTTON1_CLICK);
            PendingIntent button1PendingIntent = PendingIntent.getBroadcast(context, 0, button1Intent,PendingIntent.FLAG_IMMUTABLE );
            views.setOnClickPendingIntent(R.id.button1, button1PendingIntent);
            Intent button2Intent = new Intent(context, NewAppWidget.class);
            button2Intent.setAction(ACTION_BUTTON2_CLICK);
            PendingIntent button2PendingIntent = PendingIntent.getBroadcast(context, 1, button2Intent,PendingIntent.FLAG_IMMUTABLE);
            views.setOnClickPendingIntent(R.id.button2, button2PendingIntent);
            views.setOnClickPendingIntent(R.id.imageRightOfButtons, getPendingIntent(context,appWidgetId));
            appWidgetManager.updateAppWidget(appWidgetId, views);
        }
    }
