ERROR The action 'NAVIGATE' with payload {"name":"Home"} was not handl-CodePudding

I am building an app with React Native and Expo and i am trying to implement authentication in the app but i am getting this error and i can't find a solution.

Basically i have 2 navigation stacks AppStack & AuthStack in my App.js. AppStack will be shown if the user is authenticated and if the user is not authenticated then AuthStack will be shown to the user.

So i am conditionally rendering the stacks with ternary operator as you can see in the App.js code below. The stacks are working fine i mean if user is authenticated then AppStack is shown and if not then AuthStack is shown.

Now the Signin screen is present in AuthStack and when a user logs in successfully he should be navigated to Home screen navigation.navigate("Home") which is present in AppStack. But when a user logs in it throws me this error.

ERROR  The action 'NAVIGATE' with payload {"name":"Home"} was not handled by any navigator.                                                                                    
Do you have a screen named 'Home'?                                                      
If you're trying to navigate to a screen in a nested navigator, see https://reactnavigation.org/docs/nesting-navigators#navigating-to-a-screen-in-a-nested-navigator.

This is a development-only warning and won't be shown in production

Here is the App.js code:

const AppStack = () => {
    return (
      <>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={Home} options={{headerStyle: {backgroundColor: "#000"}, headerTintColor: "white"}} />
        <Stack.Screen name="Forgot Password" component={ForgotPwd} options={{headerStyle: {backgroundColor: "#2a454e"}, headerTintColor: "white"}} />
        <Stack.Screen name="Check Your Inbox" component={ForgotPwdNext} options={{headerStyle: {backgroundColor: "#00dfc0"}, headerTintColor: "#3a5864"}} /> 
        <Stack.Screen name="Change Password" component={ChangePwd} options={{headerStyle: {backgroundColor: "#e5322b"}, headerTintColor: "white"}} />
      </Stack.Navigator>
    </>  
      )
  }
  
  const AuthStack = () => {
    return (
      <>
        <Stack.Navigator>
          <Stack.Screen name="Welcome" component={Welcome} options={{headerStyle: {backgroundColor: "#1b4152"}, headerTintColor: "white"}} /> 
          <Stack.Screen name="Signin" component={Signin} options={{headerStyle: {backgroundColor: "#5549ab"}, headerTintColor: "white"}} />
          <Stack.Screen name="Signup" component={Signup} options={{headerStyle: {backgroundColor: "#26dec0"}, headerTintColor: "#35474f"}} /> 
          <Stack.Screen name="Verify Phone Number" component={VerifyPhone} options={{headerStyle: {backgroundColor: "#d268cc"}, headerTintColor: "white"}} />
          <Stack.Screen name="Logged Out" component={LoggedOut} options={{headerStyle: {backgroundColor: "#5a6e7f"}, headerTintColor: "white"}} />
       </Stack.Navigator> 
      </>
      )
  }
  
  return (
    <NavigationContainer style={styles.root}>
      <StatusBar style="light" />
      {isAuthenticated ? <AppStack /> : <AuthStack />}
    </NavigationContainer>
  ) 
}

CodePudding user response：

This exact problem is addressed here.

Your AuthStack doesn't know anything about AppStack and vice versa. Hence navigation.navigate("Home") from AuthStack will fail.

When isAuthenticated is changed React Navigation will automatically navigate to correct screen. This is possible when isAuthenticated state is managed globally using React Context (or by using any state management library like Redux, Zustand etc).

Check this official example which more or less resembles your authentication flow.

CodePudding user response：

You cannot navigate from Signin to Home. You can only navigate between screens that share a parent navigator or grandfather if you have nested navigators. Here is a quote from the doc talking about this specific navigator they created:

Said another way, we can only navigate to routes that have been defined on our navigator — we cannot navigate to an arbitrary component

The common way is to have a way to change isAuthenticated to true in Signin instead of navigating, and the below condition in App.js will do the job. For that you can pas a state setter from App to Signin or use a context...

{isAuthenticated ? <AppStack /> : <AuthStack />}
