[BUG] Regarding Proguard

[omertanveer]

Hi,

Locally the debug build with stripe integration with flow controller is working fine. But when making a beta build for which we are using proguard, I end up with a crash:

Fatal Exception: n40.p0
Function 'loadPaymentOption' (JVM signature: loadPaymentOption$paymentsheet_release(Lcom/stripe/android/paymentsheet/model/PaymentOption;Lkotlin/coroutines/Continuation;)Ljava/lang/Object;) not resolved in class com.stripe.android.paymentsheet.model.PaymentOptionFactory: internal final suspend fun loadPaymentOption(paymentOption: com.stripe.android.paymentsheet.model.PaymentOption): android.graphics.drawable.Drawable defined in com.stripe.android.paymentsheet.model.PaymentOptionFactory | loadPaymentOption$paymentsheet_release(Lcom/stripe/android/paymentsheet/model/PaymentOption;Lu30/d;)Ljava/lang/Object;

Can someone please help with anything that can be added to proguard to avoid this crash from happening?

Had to add this to proguard rules for now to prevent crash:
-keep class kotlin.Metadata {*;}
-keep class kotlin.coroutines.Continuation
