Answer 1

Initially

import {Navigator}

Define Navigator inside the

render

function of

index.android.js

like this

render() {
    return (
      <Navigator
          initialRoute={{id: 'HomePage', name: 'Index'}}
          renderScene={this.renderScene.bind(this)}
          configureScene={(route) => {
            if (route.sceneConfig) {
              return route.sceneConfig;
            }
            return Navigator.SceneConfigs.FloatFromRight;
          }} />
    );
}

Then define the

renderscene function

like this

renderScene(route, navigator) {
    var routeId = route.id;
    if (routeId === 'HomePage') {
      return (
        <HomePage
          navigator={navigator} />
      );
    }
    if (routeId === 'DetailPage') {
      return (
        <DetailPage
          navigator={navigator}

          {...route.passProps} 
          />
      );
    }

}

Specify the property

{...route.passProps}

for passing values to a screen. Here I have given it inside the DetailPage

Then you can use

passProps

for calling the next page. In my case

DetailPage

this.props.navigator.push({
      id: 'DetailPage',
      name: 'DetailPage',
      passProps: {
      name:value

    }
});

Answer 2

You need to pass the props to another page using navigator

 this.props.navigator.push({
    name: 'Home',
    passProps: {
      name: property
    }
  })
