react-native-navigation v2: Get current route

Question

I want to forbid BackButton closing app when in the root of the navigator. How can I detect current route?

Or maybe there is builtin react-native-navigation method to work with backbutton?

Answer 1

Getting current Route

this.props.navigation.state.routeName;

Handle Back button

import { BackHandler } from 'react-native';

constructor(props) {
    super(props)
    this.handleBackButtonClick = this.handleBackButtonClick.bind(this);
}

componentWillMount() {
    BackHandler.addEventListener('hardwareBackPress', this.handleBackButtonClick);
}

componentWillUnmount() {
    BackHandler.removeEventListener('hardwareBackPress', this.handleBackButtonClick);
}

handleBackButtonClick() {
    //Handle ur back functionality here.
}
