react-native - 路线“Feed”的组件必须是React组件

我试图理解反应导航，并且我正在设置一个概念应用程序来理解。

首先，我遇到的是错误消息“路线“ SomeRoute”的组件必须是React组件”

我知道这意味着什么，但我不明白为什么会引发此错误。

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;

如我所见，Feed正在扩展React.Component，并且还导出了默认的类名“ Feed”。

这似乎是一个非常基本的错误，我在这里做错了什么？

最佳答案

好的，我找到了。

根目录中的“ Feed”路由具有“ Screen”属性，而不是“ screen”属性。

可以在屏幕前错误关闭。
