🔨 Initialization

initialize in main.dart

String privateKey = await rootBundle.loadString('assets/keys/merchant_private_key.pem');
String publicKey = await rootBundle.loadString('assets/keys/easypaisa_public_key.pem');

EasypaisaWithRSA.initialize(
'username', //merchant account username

);

// Accessing the result properties
print('API Response: ${result.response}');
print('Signature: ${result.signature}');
print('Is Signature Valid: ${result.isSignatureValid}'); // based on signature validation transaction can be marked as verified or suspicious.
