Stream IO Feeds React Native 和 React Navigation

Question

我正在使用 Stream IO Feeds API for React Native. I was trying to follow this example，但在尝试运行应用程序时出现此错误：

Error: Couldn't find a navigation context. Have you wrapped your app with 'NavigationContainer'? See https://reactnavigation.org/docs/getting-started for setup instructions.

This error is located at:

    in Feed (created by FlatFeed)
    in FlatFeed (created by HomeFeed)
    in StreamApp (created by HomeFeed)

我注意到每当我使用带有 React 导航容器的 Stream Flatfeed 时都会出现此问题。当提要是独立的（不是任何 stack/tab 导航的一部分）时，它会正确呈现。我正在使用 Node v16.13.1 在 Android 上测试应用程序。对此有什么建议吗？

我能够在较小的应用程序上重现此问题：

导入语句：

    import React, { Fragment } from 'react';
    import { Text, View } from 'react-native';
    import SafeAreaView from 'react-native-safe-area-view';
    import { SafeAreaProvider } from 'react-native-safe-area-context';
    import { NavigationContainer } from '@react-navigation/native';
    import { createMaterialTopTabNavigator } from '@react-navigation/material-top-tabs';
    import { StreamApp, FlatFeed, Activity, LikeButton, StatusUpdateForm, ReactionIconBar} from 'expo-activity-feed';
    
    const Tab = createMaterialTopTabNavigator();

第一个选项卡（带流提要）：

    function Feed() {
      return (
        <StreamApp
        apiKey={apiKey}
        appId={appId}
        token={token}>
        <FlatFeed
          Activity={props => (
            <Fragment>
              <Activity
                {...props}
                notify
                Footer={
                    <ReactionIconBar>
                      <LikeButton {...props} />
                    </ReactionIconBar>
                }
              />
            </Fragment>)}/>
        <StatusUpdateForm feedGroup='timeline' />
      </StreamApp>
      )
    }

第二个标签：

    function Screen2() {
      return (
        <View style={{ flex: 1 }}>
          <Text>Screen 2</Text>
        </View>
      );
    }

导出（所有代码包括之前的代码都在App.js）：

    export default App = () => {
      return (
        <SafeAreaProvider>
          <SafeAreaView style={{ flex: 1 }}>
              <NavigationContainer>
                <Tab.Navigator
                  screenOptions={{
                    tabBarLabelStyle: { fontSize: 12 },
                    tabBarItemStyle: { width: 100 },
                  }}
                >
                  <Tab.Screen name="Feed" component={ Feed } />
                  <Tab.Screen name="Screen2" component={ Screen2 } />
                </Tab.Navigator>
              </NavigationContainer>
          </SafeAreaView>
        </SafeAreaProvider>
      );
    };

我们在 GetStream 的 GitHub 存储库中问了一个类似的问题，发现我们需要升级到 Expo 44 并将 expo-activity-feed 降级到版本 1.0.0 并确保它没有 ^ 在 1.0.0 的末尾。希望对你也有帮助。
