I developed an app in flutter, in this app we are keeping a unique id using UUID package, and I am storing that uuid using shared preferences for guest login purpose.
We tested app on emulator, simulator and 10 to 15 other devices and its working as expected.
but my client has motorola edge 5G UW (2021) phone.
when he tries to use it, he is not able to store that uuid in shared preferences.
as I know for shared preferences there is no permission required and for uuid package as well.
Now I am not sure how to find out that error because my client is not able to install debug apk as well.
Looking for solution, how to find the error that he is getting on his device due to one of these packages, he just gets the grey screen.
Thankyou very much
