Buttons that doesn't appear when render
0
I followed a video tutorial to add authentication in a React app with expo. The problem is the 2 buttons "Log In" and "Sign Up" does not display
Could you tell me why ?
Sometimes there is such problems when the element is not charged yet, but I don't understand why it would be the case here.
firebase.initializeApp({
apiKey: XXXXXXX,
authDomain: XXXXXXX,
databaseURL: XXXXXXX,
projectId: XXXXXXX,
storageBucket: XXXXXXX,
messagingSenderId: XXXXXXX
});
export default class Login extends React.Component {
state = {
email:'',
password:'',
error:'',
loading:false
};
onLoginPress(){
this.state({error:'', loading:true});
firebase.auth().signInWithEmailAndPassword(email, password)
.then(()=>{
this.state({error:'',loading:false})
this.props.navigation.navigater('Home')
})
.catch (()=> {
this.state({error:"authentif faild", loading:false});
})
}
onSignUpPress(){
this.state({error:'', loading:true});
firebase.auth().createWithEmailAndPassword(email, password)
.then(()=>{
this.state({error:'',loading:false})
this.props.navigation.navigater('Home')
})
.catch (()=> {
this.state({error:"authentif faild", loading:false});
})
}
renderButtonOrLoading(){
if(this.state.loading) {
return <Text> Loading </Text>
}
return
<View>
<Text> Loading </Text>
<Button
onPress={this.onLoginPress.bind(this)}
title='Log In'/>
<Button
onPress={this.onSignUpPress.bind(this)}
title="Sign Up"/>
</View>
}
render() {
return(
<View>
<FormLabel>Email</FormLabel>
<FormInput onChangeText={email => this.setState({email})}/>
<FormLabel>Password</FormLabel>
<FormInput onChangeText={password => this.setState({password })}/>
{this.renderButtonOrLoading()}
</View>
)
}
}

I believe its because you are missing () on your return
renderButtonOrLoading(){
if(this.state.loading) {
return <Text> Loading </Text>
}
return (
<View>
<Text> Loading </Text>
<Button
onPress={this.onLoginPress.bind(this)}
title='Log In'/>
<Button
onPress={this.onSignUpPress.bind(this)}
title="Sign Up"/>
</View>
)
}

I think you have missed to add round brackets for return method.
renderButtonOrLoading(){

}
return (
