class MyTransactionScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Initiate Transaction'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () async {
            try {
              await LightSpeedPay().initiateTransaction(
                "100.00",
                "unknown",
                "Sample transaction",
                "123456",
                "John Doe",
                "john.doe@upi", // Example VPA ID, replace with actual one if needed
                "YOUR_API_KEY",
                "YOUR_API_SECRET",
              );
              print('Transaction initiated successfully');
            } catch (e) {
              print('Error initiating transaction: $e');
            }
          },
          child: Text('Initiate Transaction'),
        ),
      ),
    );
  }
}

Replace "YOUR_API_KEY" and "YOUR_API_SECRET" with your actual API credentials from LightSpeedPay Dashboard.
