payWithApp static method
Pay directly with a specific UPI app (no picker shown)
Use this when you already know which app the user wants.
Implementation
static Future<UpiResponse?> payWithApp({
required UpiPayment payment,
required UpiApp app,
}) async {
if (!UpiValidator.isValidVpa(payment.payeeVpa)) {
throw UpiException('Invalid UPI VPA: "${payment.payeeVpa}"');
}
final upiUrl = UpiUrlBuilder.build(payment);
return _platform.launchUpiApp(
upiUrl: upiUrl,
packageName: app.packageName,
);
}
