NullPointerException in GallerySaver.finishWithSuccess when saving image

[NGUYENDINHATK2]

I encountered a fatal crash when trying to save an image with GallerySaver:

Steps to reproduce:

1. Download an image to cache directory (/data/user/0/<package>/cache/...jpg)
2. Call GallerySaver.saveImage(path, albumName: ...)
3. App crashes with NPE

Notes:

• It seems finishWithSuccess() is being called with a null result.
• This happens more often with cached files, especially on Android 11+ (Scoped Storage).
• saveImage returns false for some images, and sometimes the app crashes completely.

Expected:

• Should either return false or throw a handled exception, not crash the app.
• Library should handle null filePath safely.

Workaround:

• Migrated to gallery_saver_plus which seems to have fixed this.
