How to use navigation.navigate from a component outside the stack.navigation

Try this:

Create a new file named: RootNavigation.js

// RootNavigation.js

import * as React from 'react';

export const navigationRef = React.createRef();

export function navigate(name, params) {
  navigationRef.current?.navigate(name, params);
}

// file where you have the navigation

import {navigationRef} from './path/to/RootNavigation';

      <NavigationContainer ref={navigationRef}>
      .....
        <Footer />
      </NavigationContainer>

And Footer.js should be something like this:

// Footer.js

import React from 'react';
import {View, Button} from 'react-native';
import * as RootNavigation from './path/to/RootNavigation';

const Footer= () => {
  return (
    <View>
      <Button
        title={'Go to'}
        onPress={() =>
          RootNavigation.navigate('screenName ', {userName: 'Lucy'})
        }
      />
    </View>
  );
};

export default Footer;

For more info you can read the documentation. https://reactnavigation.org/docs/navigating-without-navigation-prop/

The components outside of the Stack.Screen components do not receive the navigation prop. So in this case, you have to get the NavigationContainer using refs in your footer component, as follows:

1. Create a ref with const myRef = React.createRef()
2. pass it to the <NavigationContainer ref={myRef}>, and
3. use that ref to navigate, myRef.current?.navigate(name, params).

It is all explained here. The docs here separate the creation of the ref in a new file, to allow you to import the ref without dependency loops/ issues. As the docs state, you can now call RootNavigation.navigate('ChatScreen', { userName: 'Lucy' }); in any js module, not just in a react component.

In your case though, you don't need the ref in separate file.

const Stack = createStackNavigator();
const navigationRef = React.createRef();

const App = () => {    
  return (
    <Provider store={store}>
      <NavigationContainer ref={navigationRef}>
        <Header />
        <Stack.Navigator>
          <Stack.Screen
            name="Home"
            component={HomeScreen}
            options={{
            headerShown: false
          }}
          />
          <Stack.Screen
            name="Login"
            component={LoginScreen}
            options={{
            headerShown: false
          }}
          />
        </Stack.Navigator>
        <Footer navigationRef={navigationRef}/>
      </NavigationContainer>
    </Provider>
  );
};

And in <Footer/> use navigationRef.current?.navigate(name, params)

From the documentation. https://reactnavigation.org/docs/connecting-navigation-prop/

import * as React from 'react';
import { Button } from 'react-native';
import { useNavigation } from '@react-navigation/native';

function GoToButton({ screenName }) {
  const navigation = useNavigation();

  return (
    <Button
      title={`Go to ${screenName}`}
      onPress={() => navigation.navigate(screenName)}
    />
  );
}
