The action 'NAVIGATE' with payload {"name":"Home","params":{"user":{"id":"VUUpROQPtKaXVef15e5XhxXNLrm1","email":"[email protected]","fullName":"snertp0"}}} was not handled by any navigator.
Do you have a screen named 'Home'?
I have this problem when I try to log in or register, I don't know how to solve it. I have tried several ways that I have found but I can't find the solution, Thank you!
This is all the code I use, so I don't understand why you tell me there is no Screen Home, if I am using it. I've been checking several times all the code but I can't find where that fault may be, since I think I'm calling it all correctly.

Reset to default 3in your App.js, you have the following:
<Stack.Screen name="Home">
{(props) => <HomeScreen {...props} extraData={user} />}
</Stack.Screen>
it should be
<Stack.Screen name="HomeScreen">
{(props) => <HomeScreen {...props} extraData={user} />}
</Stack.Screen>
then you need to make the following changes to the navigator:
return (
<NavigationContainer>
<Stack.Navigator initialRouteName={user ? 'HomeScreen' : 'Login'}>
<Stack.Screen name="HomeScreen">
{(props) => <HomeScreen {...props} extraData={user} />}
</Stack.Screen>
<Stack.Screen name="Login" ponent={LoginScreen} />
<Stack.Screen name="Registration" ponent={RegistrationScreen} />
)}
</Stack.Navigator>
</NavigationContainer>
);
on your login screen change
navigation.navigate(HomeScreen, {user});
to
navigation.navigate("HomeScreen", {user});
