• Initiate Payment Sheet: Initialize the payment sheet with customizable parameters.
• Present Payment Sheet: Display the payment sheet within your Flutter app.

To use this package in your Flutter project, follow these steps:

Add flutter_hyperswitch to your pubspec.yaml file:

Then, run:

dart
flutter pub get

Import the Package

dart
import 'package:flutter_hyperswitch/flutter_hyperswitch.dart';

final _hyper = FlutterHyperswitch();

Initialize the payment sheet with required parameters:

dart
//Set up HyperConfig parameters
_hyper.init(HyperConfig(publishableKey: 'your_publishable_key'));

// Set up the payment parameters
PaymentSheetParams params = PaymentSheetParams(
  clientSecret: 'your_client_secret',
  // Add other required parameters
