Can't get token on iOS

[uendellima]

Is there any configuration to be done on iOS to work? on Android i can get the token, but on iOS it stucks on a infinite loading using b2c_with_button widget and no function is called, neither onSuccess nor onFailure.

Actually, my redirect url is: <appId>://callback

Hi @unleed

There is an improvement to the button login flow in aad_b2c_webview version: ^0.1.1

Below is a usage example that may help in testing. I look forward to your feedback to know if it worked correctly!
