路由“Feed"的组件必须是 React 组件

问题描述

我正在尝试理解 reactnavigation 并且我正在设置一个概念应用程序来理解.

i am trying to understand reactnavigation and i am setting up a concept app to understand.

我一开始遇到的困难是，我收到错误消息路由SomeRoute"的组件必须是 React 组件"

What i am struggling at first is, that i get the Error Message "The component for route "SomeRoute" must be a React Component"

我知道这意味着什么，但我不明白为什么会抛出这个错误.

I do know, what it means, but i do not understand why this error is thrown.

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)

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 )

and 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;

正如我所见，Feed 正在扩展 React.Component 并导出默认的类名Feed".

As i can see, Feed is extending React.Component and also exporting a default Classname "Feed".

这似乎是一个非常基本的错误，我在这里做错了什么?

It seems to be a very Basic Mistake, what am i doing wrong here?

推荐答案

好的，我找到了.

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

The route "Feed" in Root has a "Screen" property instead of a "screen" Property.

可以在屏幕前错误关闭.

can be closed by error in front of screen.
