Future createUser(BackendlessUser user) async {
String result = ‘OK’;
try {
await Backendless.userService.register(user);
NoteEntry emptyEntry = NoteEntry(notes: {}, username: user.email);
await Backendless.data
.of(‘NoteEntry’)
.save(emptyEntry.toJson())
.onError((error, stackTrace) {
result = error.toString();
});
} catch (e) {
result = getHumanReadableError(e.toString());
}
notifyListeners();
return result;
}

Is there an error when you run the code?

This forum is the only mechanism to get technical support, we do not offer support via whatsapp or other messengers.

Have you debugged the code to see if you get to the point when the registration call occurs? Does the code get the return value?

It does not get a return value let me try sharing my whole code with you here

class InitApp {

That’s my code but I cannot register a new user on backendless

if you believe the problem is in our SDK/API, please create the smallest possible program that reproduces the issue. As a part of support, we will be happy to assist with the functionality provided by Backendless, but we cannot debug or review your complete program listings.

Regards,
Mark

I have done that but it’s not working

Can you share the simple program? It should be as simple as:

  1. Init app
  2. Register user (use hard-coded values).
