Execution failed for task ':app:mergeExtDexDebug'.

Hi all, I added "superwallkit_flutter: ^1.1.9" to my project, but I'm still encountering the following error. I also tried this on a newly created project, and the same issue occurred. Below are the error details and the output from flutter doctor.

Hyy @Borys520 ,

I'm running into the same issue you addressed when I use version "superwallkit_flutter: ^1.1.9". Can you share how you solved it?

Hi, I upgraded gradle to 8.4 and kotlin to 1.9.23 and it worked
