App crashes when payfort package is used.

[bilalep]

Problem:
App crashing when "Allow Google Location History" dialogue pops up.

Even though the exception occurs when a Google Maps package dialogue appears, the stack trace refers to a method in flutter-amazonpaymentservices and when i remove this package the error goes away.

Any Solution ? Android app is crashing even after payment success.
