I have set validation to check valid format of UPI.
String validateUpiID(String value) {
String pattern = '[a-zA-Z0-9.\-_]{2,256}@[a-zA-Z]{2,64}';
RegExp regExp = RegExp(pattern);
if (value.isEmpty) {
return 'Please Enter UPI ID';
} else if (!regExp.hasMatch(value)) {
return 'Please Enter valid UPI ID';
}
return "";
}
But Now I'm stuck there, How do I check that entered UPI is exist or in working mode ?
Use package upi_pay: https://pub.dev/packages/upi_pay
After calling the method initiateTransaction, you can get the status of the transaction
Future doUpiTransation(ApplicationMeta appMeta) {
final UpiTransactionResponse response = await UpiPay.initiateTransaction(
amount: '100.00',
app: appMeta.application,
receiverName: 'John Doe',
receiverUpiAddress: 'john@doe',
transactionRef: 'UPITXREF0001',
transactionNote: 'A UPI Transaction',
);
print(response.status);
}
