Firebase Phone Authentication in React native

[Midhun Vazhoor]

How we can use Firebase Ohone authentication in react native mobile apps. 

When i use with this package 'react-native-firebase' ,

I got error "Phone number is invalid format" even i give phone number with country code.

Check that you're passing the number properly to the call (e.g. try hard coding the number). If that doesn't work, we'd probably need to see some minimal code that demonstrated the problem (e.g with that hard coded number) in order to help.

i will prove main codes and will attach package.json and /app/build.gradle 

import firebase from 'react-native-firebase';

export default class PhoneAuthTest extends Component {

constructor(props) {

super(props);

this.unsubscribe = null;

this.state = {

user: null,

message: '',

codeInput: '',

phoneNumber: '',//'+91',

confirmResult: null,

};

}

componentDidMount() {

// debugger;

console.log('test')

this.unsubscribe = firebase.auth().onAuthStateChanged((user) => {

if (user) {

this.setState({ user: user.toJSON() });

} else {

// User has been signed out, reset the state

this.setState({

user: null,

message: '',

codeInput: '',

phoneNumber:'' ,//'+91',

confirmResult: null,

});

}

});

}

signIn = () => {

debugger;

const { phoneNumber } = this.state;

this.setState({ message: 'Sending code ...' });

console.log('signInWithPhoneNumber')

var phno=phoneNumber.toString();

console.log(phoneNumber);

console.log('ph:'+phno);

firebase.auth().verifyPhoneNumber('com.login_demo_2',phoneNumber,60) //'com.login_demo_2'

.then(confirmResult => this.setState({ confirmResult, message: 'Code has been sent!' }))

.catch(error => this.setState({ message: `Sign In With Phone Number Error: ${error.message}` }));

};

renderPhoneNumberInput() {

const { phoneNumber } = this.state;

return (

<View style={{ padding: 25 }}>

<Text>Enter phone number:</Text>

<TextInput

autoFocus

style={{ height: 40, marginTop: 15, marginBottom: 15 }}

onChangeText={value => this.setState({ phoneNumber: value })}

placeholder={'Phone number ... '}

value={phoneNumber}

/>

<Button title="Sign In" color="green" onPress={this.signIn} />

</View>

);

}
