如何在使用createStackNavigator时使用React Native React导航添加firebase屏幕跟踪分析？

import firebase from 'firebase';
import { NavigationActions } from 'react-navigation';

import firebase from 'firebase';

const firebaseConfig = {
  // Firebase配置信息
};

firebase.initializeApp(firebaseConfig);

const trackScreen = (screenName) => {
  firebase.analytics().setCurrentScreen(screenName);
};

const trackScreenTransition = (prevState, newState) => {
  const currentScreen = getActiveRouteName(newState);
  const prevScreen = getActiveRouteName(prevState);

  if (prevScreen !== currentScreen) {
    trackScreen(currentScreen);
  }
};

const getActiveRouteName = (state) => {
  const route = state.routes[state.index];

  if (route.state) {
    return getActiveRouteName(route.state);
  }

  return route.name;
};

const addScreenTracking = (navigator) => {
  const prevGetStateForAction = navigator.router.getStateForAction;

  navigator.router.getStateForAction = (action, state) => {
    if (state && action.type === NavigationActions.NAVIGATE) {
      trackScreenTransition(state, prevGetStateForAction(action, state));
    }

    return prevGetStateForAction(action, state);
  };
};

import ScreenTracking from './ScreenTracking';

const AppNavigator = createStackNavigator({
  // 导航器配置
});

ScreenTracking.addScreenTracking(AppNavigator);
