路径"Feed"的组件必须是React组件

Question

我正在尝试理解反应导航,我正在设置一个概念应用程序来理解.

我最初在努力的是,我得到错误信息"路由的组件"SomeRoute"必须是一个React组件"

我知道,这意味着什么,但我不明白为什么会抛出这个错误.

我有以下设置:

App.js:

import React from 'react';
import { Root } from './config/router';
import { SafeArea } from 'react-native';
class App extends Component {
    render() {
        return <Root />;
    }
}
export default App;

router.js(config/router.js)

import React from 'react';
import { DrawerNavigator, TabNavigator, StackNavigator } from 'react-navigation';

import Feed from './../components/Feed';
import Search from './../components/Search';
import Favorites from './../components/Favorites';

import TextList from './../components/ComingSoon';
import Detail from './../components/Detail';
import Downloads from './../components/Downloads';

export const FeedStack = StackNavigator({

    Feed: {
        screen: Feed,
        navigationOptions: {
            title: 'Machines'
        }
    },
    List: {
        screen: TextList,
        navigationOptions: {
            title: 'List View'
        }
    },
    Detail: {
        screen: Detail,
        navigationOptions: {
            title: 'Detail'
        }
    }
});


export const TabStack = TabNavigator({
    Dashboard: {
        screen: FeedStack,
        navigationOptions: {
            title: 'Dashboard'
        }
    },
    Search: {
        screen: Search,
        navigationOptions: {
            title: 'Search'
        }
    },
    Favorites: {
        screen: Favorites,
        navigationOptions: {
            title: 'Favorites'
        }
    }
});


export const DownloadStack = StackNavigator({
    Downloads: {
        screen: Downloads,
        navigationOptions: {
            title: 'Downloads'
        }
    }
});

export const Root = DrawerNavigator({
    Feed: {
        Screen: TabStack,
        navigationOptions: {
            title: 'Machines'
        }
    },
    Downloads: {
        screen: DownloadStack
    }
});

和Feed.js(components/Feed.js)

import React from 'react';

import { View, Text } from 'react-native';

class Feed extends React.Component {

    render() {
        return (
            <View>
                <Text>Hallo Feed Soon</Text>
            </View>
        );
    }
}

export default Feed;

正如我所看到的,Feed正在扩展React.Component并导出默认的Classname"Feed".

这似乎是一个非常基本的错误,我在这里做错了什么？

好吧,我找到了.

Root中的路径"Feed"具有"Screen"属性而不是"screen"属性.

可以通过屏幕前面的错误关闭.
