I'm building a mobile app with React Native in an expo managed project and I'm using React Navigation. I'm using a Stack navigation and Tabbar navigation. I'm having trouble adding a simple button into the Stack screen header. My goal is to add an 'add' button on the right side of the header.

I followed the React Navigation documentation on how to add this button, but it didn't work, I'm getting this error:

Error: Text strings must be rendered within a <Text> component.

I added the headerRight option into Stack.Screen options as shown int the documentation, but it doesn't work and I get mentioned error.

Does anyone know how to fix this? Did anyone encountered the same problem?

Here is a link to my git repo with the whole project. The problem is with the PlaylistScreen.js file in screens folder.

Here is the code in question:

const PlaylistsScreen = () => {
  const Stack = createNativeStackNavigator();
  return (
        <Stack.Navigator>
          <Stack.Screen
            name="PlaylistList"
            component={PlaylistList}
            options={{
              headerTitle: "Playlisty",
              headerRight: () => (
               <Button
                 onPress={() => alert('This is a button!')}
                 title="Info"
                 color="#fff"
               />
             ),
            }}
          />
        </Stack.Navigator>
  );
};

I have also tried this, which resulted in the same error:

const PlaylistsScreen = () => {
  const Stack = createNativeStackNavigator();
  return (
        <Stack.Navigator>
          <Stack.Screen
            name="PlaylistList"
            component={PlaylistList}
            options={{
              headerTitle: "Playlisty",
              headerRight: () => (
                <View>
                  <Text>{"right"}</Text>
                </View>
              ),
            }}
          />
        </Stack.Navigator>
  );
};

Here is my navigation structure:

<NavigationContainer>
   <Tab.Navigator>
      <Tab.Screen/>
   </Tab.Navigator>
</NavigationContainer>

The Tab.Screen contains a component with the Stack.Navigator like this:

<Stack.Navigator>
  <Stack.Screen/>
</Stack.Navigator>

And that is the Stack.Screen I'm trying to add the header button to.

Hey you were importing the native-web components which doesn't work on mobiles change this import in your PlaylistsScreen.js from

import { Button, Text, View } from "react-native-web";

to

import { Button, Text, View } from "react-native";
