undefined is not an object(evaluating 'container.setState')

Hai, I run your demo project,and check in device it working fine, But in index.ios.js, i added the some code for navigator, added some form code init.when click on signIn button i want to show the webRtc screen for that screen i just copied the main.js file code in RTcWebdemo project and added in my code, here is my code index.ios.js

if (!window.navigator.userAgent) {
  window.navigator.userAgent = "react-native";
}
'use strict';
import React,{Component} from 'react';
var SignIn = require('./SignIn');
import {
  AppRegistry,
  StyleSheet,
  Navigator,
  AsyncStorage,
} from 'react-native';
class RCTWebRTCDemo extends Component {
  render() {
    return (
            <Navigator
                initialRoute={{
                  component:SignIn  //component declaration
                }}
                configureScene={(route) => ({
                  ...Navigator.SceneConfigs.HorizontalSwipeJump,
                  gestures: false
                })}
                renderScene={(route, navigator) =>{
                  return <route.component navigator={navigator} {...route.passProps} />;
                }}/>
        );
  }
};

signIn.js

onSignin(){
    this.props.navigator.push({
      component: main
    })
}

When click on signIn button of the below image calling the above function in main component i added the main.js file code

but when i run project before clicking on signIn button, It shows some error like this

please give me suggestions that how to resolve this

make sure you set container = this in the main WebRTCDEMO Component’s ComponentDidMount.

my suggestion would be: try to understand demo main.js logic, and applied it in to your own logic.

Nothing actionable for the plugin itself, closing.
