没有导航道具的 React 导航导航示例不起作用 [英] React navigation navigate without navigation props example not working

问题描述

我有一个 react-native 应用程序，我正在使用新的 Context API 来管理存储和内容，现在我将 createAppContainer(AuthNavigator) 包装在 <Provider> 由上下文 API 创建，因此为了从上下文 API 文件导航，我尝试通过创建 NavigationService 并传递在文档中找到的完全相同的示例来执行AppContainer 的 ref 到 NavigationService 并使用 { NavigationActions }，不知何故它不起作用也没有抛出任何种类错误

I have a react-native app and I'm using the new Context API to manage the storage and stuff, now I'm wrapping the createAppContainer(AuthNavigator) in the <Provider> created by the context api, so in order to navigate from the Context API file, I tried to do the exact same example I found in the documentation by creating the NavigationService and passing the ref of the AppContainer to the NavigationService and using { NavigationActions }, somehow it's not working neither it's throwing any kind of error

这是我的 router.js

here is my router.js

  const AuthNavigator = createSwitchNavigator(
    {
      Authenticated: Authenticated,
      UnAuthenticated: UnAuthenticated,
    },
    {
      initialRouteName: props.is_authenticated ? 'Authenticated' : 'UnAuthenticated'
    }
  )

  const Router = createAppContainer(AuthNavigator);

  return (

    <Provider style={{ width: '100%', height: '100%' }}>
      <Router ref={ ref => NavigationService.setTopLevelNavigator(ref) } />
      <DropdownAlert
        successColor="#26296A"
        titleStyle={{ fontFamily: 'DINNextLTArabic-Regular', lineHeight: 18, color: '#fff', textAlign: 'center' }}
        messageStyle={{ fontFamily: 'DINNextLTArabic-Regular', lineHeight: 16, color: '#fff', textAlign: 'center' }}
        imageStyle={{ display: 'none' }}
        ref={ (ref) => Flash.setDropDown(ref) }
      />
    </Provider>

  )

}

export default ReactNavigator;

这是我的导航服务文件

import { NavigationActions } from 'react-navigation';

let navigator;

function setTopLevelNavigator(nav_ref) { navigator = nav_ref }

function navigate(route_name, params) {
  navigator.dispatch(
    NavigationActions.navigate({
      route_name,
      params
    })
  )
}

export default {
  navigate,
  setTopLevelNavigator
};

这是我要从中导航的提供者

and here is the Provider from which i want to navigate

这是一个 React Context API

it's a React Context API

import NavigationService from '@utils/navigation-service';

onReceived(notification) {

  console.warn(notification.payload.additionalData);

  console.warn('triggered');

  NavigationService.navigate('Chat');

}

推荐答案

根据 react-navigation 网站上的示例(https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html)

Your route_name should be routeName instead according to the example on react-navigation website (https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html)

他们需要密钥 routeName &params 专门用来工作

They require the keys routeName & params specifically to work
