Exception when closing the page with the CreditCardWidget (Bad state: Cannot add new events after calling close)

[orangeyong]

When pop/closing the page with the CreditCardWidget, my Crashlytics is able to catch this error.

flutter: Bad state: Cannot add new events after calling close
flutter:
#0 _BroadcastStreamController.add (dart:async/broadcast_stream_controller.dart:243:24)
#1 _CreditCardWidgetState._processFloatingEvent (package:flutter_credit_card/src/credit_card_widget.dart:366:24)
#2 _rootRunUnary (dart:async/zone.dart:1407:47)

To Reproduce
Steps to reproduce the behavior:

1. Go to the page with CreditCardWidget
2. Pop the page with the widget
3. See error

Expected behavior
close the stream properly on dispose, maybe we need a controller to call for inside dispose?

• iOS (I think android too)
• flutter_credit_card 4.0.1
• flutter 3.16.0
