Issue with Notification Small Icon (AwesomeNotifications) Displaying Flutter Icon Instead of App Icon

Hi everyone,

I'm encountering an issue with notifications in my FlutterFlow app. The notifications display correctly with the large icon showing my app logo, but the small icon is showing the Flutter icon instead of my app icon. Below is a detailed description of the problem and the steps I've tried to resolve it.

Description:

I have a FlutterFlow app where I'm trying to implement notifications using the AwesomeNotifications package. The large icon in the notifications shows my app logo correctly, but the small icon defaults to the Flutter icon. The icons in question are located in these files:

- mademoiselle/android/app/src/main/res/mipmap-hdpi/ic_launcher.png

- mademoiselle/android/app/src/main/res/mipmap-mdpi/ic_launcher.png

- mademoiselle/android/app/src/main/res/mipmap-xhdpi/ic_launcher.png

- mademoiselle/android/app/src/main/res/mipmap-xxxhdpi/ic_launcher.png

Problem:

I don't have direct access to the code files in FlutterFlow. I can download the code, but I'm unable to edit it directly.

What I've Tried:

1. Initializing without specifying a resource:

   await AwesomeNotifications().initialize(
     null,

2. Specifying the drawable resource:

await AwesomeNotifications().initialize(   
     'resource://drawable/res_app_icon',

3. Using an asset path:

await AwesomeNotifications().initialize(    
    'assets/images/app_launcher_icon.png',

Current Messaging Initialization Code:

Here is the current version of my messaging initialization code:

        // Update the FCM token in your app's state.
        FFAppState().fcmToken = token ?? 'No token';
      });
    } else {
      // Handle the case where permission is not granted.

Request for Help:

Has anyone faced a similar issue or does anyone have any suggestions on how to ensure the small icon displays correctly as my app icon instead of the Flutter icon? Any help or guidance would be greatly appreciated!

Thank you!
