从本机导航V1迁移到V2

Question

从RN 0.55.4成功升级到0.59.10后，我发现RNN V1无法正常工作，因此我已迁移到RNN V2。另外，我还需要更改代码，因为似乎函数“ Navigation.startSingleScreenApp（{”不适用于RNN V2。使用RNN V2以及this.props.navigator无法转移道具的问题已在RNN V2中使用。

有人可以告诉我使用RNN2修改代码并使用道具设置Root的正确方法吗？还是至少让我知道如何在RN 0.59。+中使Navigation.startSingleScreenApp识别功能？我的app.js是：

import React, {Component} from 'react';
import {
    AppRegistry,
    View,
    I18nManager
} from 'react-native';
import { Global } from '@settings';
I18nManager.forceRTL(Global.RTL)
import { Navigation } from 'react-native-navigation';
import { registerScreens } from './containers';
registerScreens();

console.disableYellowBox = true;

Navigation.startSingleScreenApp({
    screen: {
        screen: 'name.SplashLayout1',
        title: "HOME",
        navigatorStyle: {
            navBarHidden: true
        }
    },
    animationType: "none"
});

我的index.js

    View,
    StyleSheet,
    Dimensions,

var {height, width} = Dimensions.get('window');
var _ = require('lodash');

export default class BlogThemeLayout extends Component {
    constructor(props) {
        super(props);

        this.state = {
            visible: true,
        };
    }
    componentWillMount() {

        WordpressService.startWordpressApp(this, Config.THEME_SETTINGS.menuID);
        EgaTheme.setTheme(Theme, null);
       // this.startApp()
    }

    startApp() {


        Navigation.startSingleScreenApp({

            screen: {

              screen: 'name.Homescreen', 
              title: 'Welcome', 
              navigatorStyle: {

    }

    render() {
