When working with React Navigation, especially in complex applications, knowing the current route name can be crucial for implementing conditional logic and enhancing user experience. This guide will walk you through the most effective method for retrieving the current route name in React Navigation using various versions and configurations.
Using React Navigation v5 and v6
For applications utilizing React Navigation v5 or v6, the useRoute hook from the @react-navigation/native package provides a straightforward solution:
import { useRoute } from '@react-navigation/native';
const route = useRoute();
console.log(route.name);This method is particularly efficient as it leverages hooks, making it suitable for functional components. The useRoute hook returns the current route object, from which you can directly access the name property.
Alternative Method for Nested Navigators
If your application involves nested navigators, you might require a more comprehensive approach to identify the active screen’s state. Here’s a method that recursively navigates through the routes:
import { NavigationState } from 'react-navigation';
const getActiveRouteState = function (route: NavigationState): NavigationState {
if (!route.routes || route.routes.length === 0 || route.index >= route.routes.length) {
return route;
}
const childActiveRoute = route.routes[route.index] as NavigationState;
return getActiveRouteState(childActiveRoute);
};
// Usage
const activeRoute = getActiveRouteState(this.props.navigation.state);This function is beneficial when you need to determine the current active screen’s state within nested navigators, such as those used in a NavigationDrawer setup.
Handling Route Changes
To manage route changes efficiently, especially when tracking the previous and current routes, you can use the following approach:
const routeNameRef = React.createRef();
routeNameRef.current = navigationRef.current.getCurrentRoute().name}
onStateChange={() => {
const previousRouteName = routeNameRef.current;
const currentRouteName = navigationRef.current.getCurrentRoute().name;
if (previousRouteName !== currentRouteName) {
// Implement your logic here
}
// Update the route name reference
routeNameRef.current = currentRouteName;
}}

;This code snippet demonstrates how to utilize a reference to track and respond to route changes dynamically.
Conclusion
By implementing these methods, you can effectively manage and utilize the current route name within your React Navigation setup, enhancing both functionality and user experience. For further optimization, consider employing automation tools that streamline your development workflow.
