The Hidden Problem Behind “Cheap” Rebuilds
Flutter is easy to start with. You build a few screens, connect an API, add some state management… and everything works. Until it doesn’t. At some point, your app stops being “small”. And then: build
AI is everywhere in modern apps. From chat assistants to recommendations and automation, most Flutter apps today rely on cloud-based models like Gemini and other APIs. But there’s a problem: What happ
AI has moved beyond static chatbots. The next wave of applications are agentic apps — AI-powered apps that can reason, act, and adapt dynamically to user needs. Instead of waiting for pre-defined screens, these apps use LLMs like Gemini (Google DeepM...
Upgrade Your Flutter Debugging with a Real Logger to Replace print()
In Flutter, RouteObserver is a powerful way to listen to navigation changes and respond when a screen (route) is pushed, popped, or replaced. This is useful for tracking page visits, analytics, logging, or refreshing data when a page is revisited.
Flutter provides a built-in NavigatorObserver class, and we can extend RouteObserver<PageRoute> to create our own.
final RouteObserver<PageRoute> routeObserver = RouteObserver<PageRoute>();
We need to pass the routeObserver to the navigatorObservers property of MaterialApp or CupertinoApp.
MaterialApp(
navigatorObservers: [routeObserver],
home: MyHomePage(),
);
To listen to route changes, a widget must implement RouteAware and register itself with the RouteObserver.
class MyScreen extends StatefulWidget {
@override
_MyScreenState createState() => _MyScreenState();
}
class _MyScreenState extends State<MyScreen> with RouteAware {
@override
void didChangeDependencies() {
super.didChangeDependencies();
routeObserver.subscribe(this, ModalRoute.of(context) as PageRoute);
}
@override
void dispose() {
routeObserver.unsubscribe(this);
super.dispose();
}
@override
void didPush() {
print('MyScreen Pushed');
}
@override
void didPop() {
print('MyScreen Popped');
}
@override
void didPopNext() {
print('Returned to MyScreen');
}
@override
void didPushNext() {
print('Navigated away from MyScreen');
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Route Observer Example")),
body: Center(child: Text("Listen to navigation changes")),
);
}
}
✅ Analytics & Tracking – Monitor which screens users visit.
✅ Logging – Track navigation history.
✅ Refreshing Data – Reload data when returning to a screen.
✅ Pause/Resume Actions – Handle background tasks when a screen is active/inactive.
💡 Pro Tip: If you're using GoRouter instead of Flutter's built-in Navigator, use GoRouterObserver instead of RouteObserver.
Try using Route Observers in your Flutter project and let me know how it goes! 🚀😃
