doorman reference

A set of functions that you can use to build a custom auth flow.
doorman is only used if you're building a fully-custom UI flow, rather than relying on withPhoneAuth or the AuthFlow. 
It is recommended you use one withPhoneAuth or AuthFlow , but hey, it's your call!
What is this?
A key part of building a fully-custom auth flow is importing doorman .
import { doorman } from 'react-native-doorman'
Table of contents
​doorman.signInWithPhoneNumber​
​doorman.verifyCode​
doorman.signInWithPhoneNumber
import { doorman } from 'react-native-doorman'
​
const signInWithPhone = async () => {
	const { success, error } = await doorman.signInWithPhoneNumber({
		phoneNumber: '+15555555555'
	})
	if (success) {
		navigate('ConfirmScreen')
	} else {
	  console.error(error)
	}
}
Arguments
Takes one argument: A dictionary with a phoneNumber field
phoneNumber format must be a string, trimmed, with no spaces, and only numbers, and a '+' at the beginning.
Returns
Promise: A dictionary with the following fields
success boolean
If true, the SMS sent to the user, and you can navigate to the next screen.
error string or undefined
If there is a message, that means that there has been an error. This is a human-readable error description.
