CodePudding user response：

try this :

return type of SetupPaymentSheetParameters should be Future

change your print method to this :

print(value.toString());

hope it will help!

CodePudding user response：

For help with the flutter_stripe package you'll want to reach out to the developers to get better explanations.

However, it looks like your value is actually attached to the result of initPaymentSheet, which is void. SetupPaymentSheetParameters should return json data for use with initPaymentSheet.
