Method is not being invoked when i press the button

Question

I am using react navigation and have added a button on the right to signout from my app using default navigation options as shown below :

const otherApp = create         


        

Answer 1

I got the solution, what i was doing wrong that i wasn't passing a call back in the onPress of the button !

logoutFromFirebase = () => {
    this.props.Signout();
    this.props.navigation.navigate(this.props.user.uid ? 'App' : 'Auth')
  }
  componentDidMount(){
    this.props.navigation.setParams({ logout : this.logoutFromFirebase })
  }

And default navigation

defaultNavigationOptions : ({navigation}) => ({
    title : 'Welcome',
    headerStyle: {
      backgroundColor: '#29434e',
      shadowColor: 'transparent',
      elevation: 0
    },
    headerRight: (
       Reactotron.log('Logout not callled'))}>
        
          Logout
        
      
    ),
  })

And now it is working fine !
