Error Handling #
When performing a payment, the SDK will automatically handle errors and display them in the UI. If a payment fails, an error message will be shown, and the user will be prompted to retry or correct the input.
Payment Success #
Once the payment is successfully completed, the user will be navigated to the success screen (PaymentSuccessScreen) showing the amount that was paid. You can customize this screen to display additional information such as the transaction ID.
Screens in SDK #

PayWithLycheeScreen: The main screen where users enter their payment details and voucher codes.
PaymentSuccessScreen: Displays when a payment is successful.
