Blank Grey Screen when running app on Android Studio

Hi everyone!

Firstly, thank you to this awesome community. Love how everyone tried to assist and help everyone. This community is tops!!!

So I created a flutterflow app and added a yearly subscription pay wall. I followed all the instruction and tutorials of how to add the paywall and revenue cat and so on. Using this document: https://docs.flutterflow.io/actions/actions/integrations/revenuecat and this video: https://www.youtube.com/watch?v=gG5f79oT5fE The app works good and there is no issue with the app, the issue is the paywall or revenue cat, at this stage I don't know which one is the issue.

So to view the paywall in action all I did was download the flutterflow APK and load/drag this into the Android studio. As soon as I hit the get started button, I get a blank grey screen. Please see attached image. At this point i'm suppose to see my bottom sheet with my subscription details but all i get a this grey screen.

Not sure if this will help but, I did notice a very strange thing. If I remove the remove my price string value on the bottom sheet popup that has the buy now and just leave the actual price in text. I get pass the grey screen and and able to see the revenue cat options but when we hit buy now its blank and i don't see the store dialogue.

Any help with be highly appreciated.
