My flutter_stripe error

[apokaliptolesamale]

Hi, I am very new development integration using flutter and Stripe. I saw some tutorial and they work. I apply the same step by step and when I going to compile usin ./gradlew build the console return the error:

Lint found 1 errors, 13 warnings. First failure:

../Android/SDK/.pub-cache/hosted/pub.dev/stripe_android-12.0.1/android/src/main/kotlin/com/reactnativestripesdk/PaymentSheetFragment.kt:446: Error: CustomPaymentMethod can only be accessed from within the same library group (referenced groupId=com.stripe from groupId=com.flutter.stripe) [RestrictedApi]
customPaymentMethod: PaymentSheet.CustomPaymentMethod,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Explanation for issues of type "RestrictedApi":
This API has been flagged with a restriction that has not been met.

Examples of API restrictions:

• Method can only be invoked by a subclass
• Method can only be accessed from within the same library (defined by the
  Gradle library group id)
• Method can only be accessed from tests.

You can add your own API restrictions with the @RestrictTo annotation.

I don know why!

You should activate custom payments in stripe itself. I would recommend contacting stripe support here as this is outside our library.
