React Native - ReactNavigation.addNavigationHelpers in not a function

问题

I was using react-navigation 1.2.1 and every thing was working fine as soon as I updated react-navigation to 2.0.0 it gives the following error. Any idea why it must be happening?

ReactNavigation.addNavigationHelpers in not a function.

import * as ReactNavigation from 'react-navigation';

render() {
    const { dispatch, nav } = this.props;
    const navigation = ReactNavigation.addNavigationHelpers({
      dispatch,
      state: nav,
      addListener,
    });

    return <AppNavigation navigation={navigation} />;
  }

//"react-navigation": "2.0.0",
//"react-native": "0.53.3",
//"redux": "^3.7.2"

回答1:

It seems that addNavigationHelpers has been removed from react-navigation's default exports, which can be seen here.

Therefore as mentioned in the docs, you need to directly add to the navigation props as

<AppNavigator navigation={{
   dispatch: this.props.dispatch,
   state: this.props.nav,
   addListener,
}} />
