React Native Navigator Route对象未定义

Question

Why am I getting an error that route is undefined in my React Native Navigator component? I thought I was pushing the correct information but I guess not? Any help would be appreciated. I'm used to working with the web so React Native is quite the shift.

So...

I want to navigate from my SplashContainer component to my SignUpForm component. So in SplashContainer I do this...

class SplashContainer extends Component {
    handleLoginFinished = () => {
        this.props.dispatch(handleAuthWithFirebase())
    }
    handleToSignUp = () => {
        this.props.navigator.push({
            signUpForm: true
        });
    }
    handleToSignIn = () => {
        this.props.navigator.push({
            signIn: true
        })
    }
    render () {

        return (
            <Splash onLoginFinished={this.handleLoginFinished} goToSignUp={this.handleToSignUp} goToSignIn={this.handleToSignIn} />
        )
    }
}

export default connect()(SplashContainer)

Then in the React Native Navigator I do this...

export default class NimbusNavigator extends Component {
    static propTypes = {
        isAuthed: PropTypes.bool.isRequired
    }
    renderScene = (route, navigator) => {
        // Keeps track of whether user is Authed or not. 
        if (this.props.isAuthed === false) {
            return <SplashContainer navigator={navigator}/>
        } else if (route.signUpForm === true) {
            return <SignUpForm navigator={navigator}/>
        }

        return <FooterTabsContainer navigator={navigator} />
    }
    configureScene = (route) => {

    }
    render () {
        return (
            <Navigator
                configureScene={this.configureScene}
                renderScene={this.renderScene}
            />
        )
    }
}

Answer 1

The route is undefined at start because you didn't give the Navigator any initial routes . You want to set either of the props initialRoute or initialRouteStack .

Assuming you want to start at a route with the name HOME, here's an example where the route { name: 'HOME' } is defined inline:

render () {
    return (
        <Navigator
            initialRoute={{ name: 'HOME' }}
            configureScene={this.configureScene}
            renderScene={this.renderScene}
        />
    )
}

Normally the navigation is set up like this:

  handleToSignUp = () => {
        this.props.navigator.push({
            name: 'signUpForm'
        });
    }

//

renderScene = (route, navigator) => {
    // Keeps track of whether user is Authed or not. 
    if (this.props.isAuthed === false) {
        return <SplashContainer navigator={navigator}/>
    } else if (route.name === 'signUpForm') {
        return <SignUpForm navigator={navigator}/>
    }

    return <FooterTabsContainer navigator={navigator} />
}
