PayButton class abstract

A widget that handles the API logic to facilitate the integration.

This widget provides an alternative UI-based integration path that wraps the API calls of the payment libraries and includes them as part of the lifecycle of the widget. As a result of that:

  1. The widget only shows if the Pay.userCanPay method returns true, or displays the childOnError widget and calls the onError function otherwise.
  2. Tapping the button automatically triggers the Pay.showPaymentSelector method which starts the payment process.

PayButton({Key? key, required PayProvider buttonProvider, required PaymentConfiguration paymentConfiguration, void onPaymentResult(Map<String, dynamic> result)?, double width = 0, double height = 0, EdgeInsets margin = const EdgeInsets.all(0), void onError(Object? error)?, Widget? childOnError, Widget? loadingIndicator})
Initializes the button and the payment client that handles the requests.
