payApi method

Future<void> payApi({ required BuildContext context, required String api, required String publishKey, required String clintID, required String customerID, required List<Product> products, String? successUrl, String? cancelUrl, required Map<String, dynamic> metadata, required bool testMode, required void onCreate(Create create), required void onCancelled(Map<String, dynamic> payStatus), required void onPaid(Map<String, dynamic> payStatus), required dynamic onError(Map error)?, })

Initiates the payment process via Thawani API.

context - The BuildContext for navigation. api - The Thawani API endpoint. publishKey - The publish key for authentication. clintID - The client reference ID. customerID - The customer ID. products - List of products to be purchased. successUrl - URL to redirect on successful payment. cancelUrl - URL to redirect on cancelled payment. metadata - Metadata associated with the payment. testMode - Flag indicating if test mode is enabled. onCreate - Callback function to be executed on successful creation of payment session. onCancelled - Callback function to be executed if payment is cancelled. onPaid - Callback function to be executed on successful payment. onError - Callback function to be executed on error.
