phone_number_hint is a Flutter package that provides a simple way to retrieve phone number hints from the user's device.It uses Phone Number Hint API

The benefits to using Phone Number Hint include the following:

  • No additional permission requests are needed
  • Eliminates the need for the user to manually type in the phone number
  • No Google account is needed
  • Not directly tied to sign in/up workflows
  • Wider support for Android versions compared to Autofill

Features #

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> getPhoneNumber() async {
    String? result;
    // Platform messages may fail, so we use a try/catch PlatformException.
    // We also handle the message potentially returning null.

    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
