I am having trouble navigating through screens with a simple button.
This is my App.js



export default class App extends Component<Props> {
render() {
return (
<AppStackNavigator/>
);
}
}
const AppStackNavigator = StackNavigator({
Login: { screen: LoginScreen },
Home: { screen: HomeScreen },

},{
navigationOptions: {
gesturesEnabled:false
}
})


Login.js



export default class Login extends Component {
render() {
return(
<SafeAreaView style={styles.container}>
<StatusBar barStyle='light-content'/>
<KeyboardAvoidingView behavior='padding' style={styles.container}>
<TouchableWithoutFeedback style={styles.container} onPress={Keyboard.dismiss}>
<View style={styles.logoContainer}>
<View style={styles.logoContainer}>
<Image style={styles.logo}
source={require('../images/logo/logo.png')}>
</Image>
<Text style={styles.title}>
Sports Chat App
</Text>
</View>
<View style={styles.infoContainer}>
<TextInput style={styles.input}
placeholder="Enter name"
placeholderTextColor='#ffffff'
keyboardType='default'
returnKeyType='next'
autoCorrect={false}
onSubmitEditing={()=> this.refs.phoneNumber.focus()}
/>
<TextInput style={styles.input}
placeholder="Enter phone number"
placeholderTextColor='#ffffff'
keyboardType='phone-pad'
ref={'phoneNumber'}
/>
<TouchableOpacity style={styles.buttonContainer}>
<Button title='LogIn' onPress={()=>this.props.navigation.navigate('Home')}/>
</TouchableOpacity>
</View>
</View>
</TouchableWithoutFeedback>
</KeyboardAvoidingView>
</SafeAreaView>
)
}
};


LoginScreen.js



class LoginScreen extends Component {
render(){
return (

<View>
<Login>
</Login>
</View>
);
}
}


I keep getting the error undefined is not an object (evaluating'_this2.props.navigation.navigate') whenever i try use the Login button in Login.js,
I want this to navigate to the home screen but cant figure out why this keeps happening.
If i try do it without the components it works fine.

Add a navigation props to Login in LoginScreen.js, Because LoginScreen has props navigation but Login don't.



   render(){
return (
<View>
<Login navigation ={this.props.navigation}>
</Login>
</View>
);
}

    Add a navigation props to Login in LoginScreen.js, Because LoginScreen has props navigation but Login don't.



       render(){
    return (
    <View>
    <Login navigation ={this.props.navigation}>
    </Login>
    </View>
    );
    }
