Here is my Widget:

class PaywallScreen extends StatefulWidget {
  const PaywallScreen({Key? key}) : super(key: key);

  @override
  State<StatefulWidget> createState() => _PaywallScreenState();
}

class _PaywallScreenState extends State<PaywallScreen> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Center(
          child: PaywallView(
            displayCloseButton: true,
            onPurchaseStarted: (Package rcPackage) {
              print('Purchase started for package: ${rcPackage.identifier}');
            },
            onPurchaseCompleted:
                (CustomerInfo customerInfo, StoreTransaction storeTransaction) {
              print('Purchase completed for customerInfo:\n $customerInfo\n '
                  'and storeTransaction:\n $storeTransaction');
            },
            onPurchaseError: (PurchasesError error) {
              print('Purchase error: $error');
            },
            onRestoreCompleted: (CustomerInfo customerInfo) {
              print('Restore completed for customerInfo:\n $customerInfo');
            },
            onRestoreError: (PurchasesError error) {
              print('Restore error: $error');
            },
            onDismiss: () {
              print('Paywall asked to dismiss');
              Navigator.pop(context);
            },
          ),
        ),
      ),
    );
  }
}

👀 We've just linked this issue to our internal tracker and notified the team. Thank you for reporting, we're checking this out!

[vegaro]

It looks like the issue is in Navigator.pop(context), I wonder if it's maybe getting called during an ongoing animation or state change, as the underlying widget is being removed from the tree. Can you try doing something like:

WidgetsBinding.instance.addPostFrameCallback((_) {
    Navigator.pop(context);
  });

Are you seeing this in the sample app in this repository?

Thanks for opening the issue!

[mpastewski]

Thanks for the prompt response. I tried to wrap it with addPostFrameCallback, but it didn't help.
I didn't try to run a sample app. I'll give it a try in the upcoming days and will get back to you.

Same issue for me, When click on 'continue' purchase button on the revenue cat paywall, the app crash. So it seems an internal paywall issue.
