Android: Filter thumbnails not loading in Banuba Video Editor SDK

[sugith-pi]

We're using the Banuba Video Editor SDK in our Flutter app. While running the app on Android, the filter thumbnails are not displaying in the editor UI.

Issue:

• When opening the Banuba editor, the list of filters appears.
• However, the thumbnails for the filters do not load—they either appear blank or as placeholders.
• The filters themselves apply correctly when selected, but their preview thumbnails are missing.

Environment:

• Platform: Android
• Flutter SDK Version: 3.32.1
• Banuba Video Editor SDK Version: 0.18.0
• Test Devices: Pixel 8, Android 15

Steps to Reproduce:

1. Launch the Flutter app on an Android device.
2. Open the Banuba Video Editor.
3. Navigate to the filters section.
4. Observe that filter thumbnails are blank.

Notes:

• Works fine on iOS (thumbnails are visible).
• Filters still function correctly when selected.
• Possibly related to resource loading, asset path issues, or thumbnail generation failure on Android.

Please advise if there's an additional configuration or asset setup required to ensure the thumbnails load properly on Android. Thank you!
