Estou tentando converter do NavigatorIOS para o Navigator e não consigo descobrir como fazer com que os passprops funcionem. Estou tentando passar duas variáveis, LRA e email para a próxima cena, mas continuo indefinido. Eu sou muito novo nisso, então desculpe se esta é uma pergunta fácil. Aqui está o meu código até agora, fique à vontade para me dar outras dicas que você vê de errado com ele!

DataEntry.js

  class DataEntry extends Component {
    constructor(props) {
      super(props);
        this.state = {
          emailString: '[email protected]',
          isLoading: false,
          message: '',
        mailerror: false,
        lraerror: false
        };
    }

  onEmailTextChanged(event) {
    this.setState({ emailString: event.nativeEvent.text });
    if (!validateEmail(this.state.emailString)){
      this.emailError = "Please enter a valid email"
      this.setState({error: true})
    }
    else{
      this.emailError = ""
      this.setState({error: false})
    }
    }

  onLRATextChanged(event) {
    this.setState({ LRAString: event.nativeEvent.text });
    if (!isValidID(this.state.LRAString)){
      this.LRAError = "Valid LRA ID is 4-10 alphanumeric characters"
      this.setState({error: true})
    }
    else{
      this.LRAError = ""
      this.setState({error: false})
    }
  }

  gotoNext() {  
    var emailtext = this.state.emailString
    var LRAtext = this.state.LRAString
    console.log(emailtext)
    this.props.navigator.push({
        id: 'PasswordView',
        name: 'Generated Password',
        email: emailtext,
        LRA: LRAtext
    });
  }

  renderScene(route, navigator) {
    var email = this.state.emailString
    var LRA = this.state.LRAString
    return (    
      <View style={styles.container}>
            <Text style={styles.description}>
                Please enter the email and LRA
            </Text>

            <View style={styles.flowRight}>
              <TextInput
                style={styles.searchInput}
                value={this.state.emailString}
                onChange={this.onEmailTextChanged.bind(this)}
                placeholder='Enter Email'/>
            </View>

            <Text style={styles.error}>
              {this.emailError}
            </Text>

            <View style={styles.flowRight}>
              <TextInput
                style={styles.searchInput}
                value={this.state.LRAString}
                onChange={this.onLRATextChanged.bind(this)}
                placeholder='Enter LRA ID'/>
            </View>

            <Text style={styles.error}>
              {this.LRAError}
            </Text>


            <TouchableHighlight style={styles.button}
                underlayColor='#99d9f4'
                onPress={this.gotoNext.bind(this)}>
               <Text style={styles.buttonText}>Retrieve Password</Text>
            </TouchableHighlight>
        <Text style={styles.description}>{this.state.message}</Text>
      </View>
    );
  }
render() {
        return (
          <Navigator
          renderScene={this.renderScene.bind(this)}
          navigator={this.props.navigator}
          navigationBar={
            <Navigator.NavigationBar style={{backgroundColor: '#48BBEC', alignItems: 'center'}}
                routeMapper={NavigationBarRouteMapper} />
          } />
        );
      }  
}

var NavigationBarRouteMapper = {
  LeftButton(route, navigator, index, navState) {
    return null;
  },
  RightButton(route, navigator, index, navState) {
    return null;
  },
  Title(route, navigator, index, navState) {
    return (
      <TouchableOpacity style={{flex: 1, justifyContent: 'center'}}>
        <Text style={{color: 'white', margin: 10, fontSize: 16}}>
          Data Entry
        </Text>
      </TouchableOpacity>
    );
  }
};


module.exports = DataEntry;
