+#### Middleware 
+If you want to hear Get events to trigger actions, you can add a GetObserver to your materialApp. This is extremely useful for triggering events whenever a specific Screen is displayed on the screen. Currently on Flutter you would have to put the event on initState and wait for a possible response in a navigator.pop (context); to get that. But with Get, this is extremely simple!
+
+##### add GetObserver();
+```dart
+void main() {
+  runApp(MaterialApp(
+    onGenerateRoute: Router.generateRoute,
+    initialRoute: "/",
+    navigatorKey: Get.key,
+    navigatorObservers: [
+        GetObserver(MiddleWare.observer), // HERE !!!
+    ],
+  ));
+}
+```
+Create a MiddleWare class
+
+```dart
+class MiddleWare {
+  static observer(Routing routing) {
+    /// You can listen in addition to the routes, the snackbars, dialogs and bottomsheets on each screen. 
+    ///If you need to enter any of these 3 events directly here, 
+    ///you must specify that the event is != Than you are trying to do.
+    if (routing.current == '/second' && !routing.isSnackbar) {
+      Get.snackbar("Hi", "You are on second route");
+    } else if (routing.current =='/third'){
+      print('last route called');
+    }
+  }
+}
+```

 ### COPY THE ROUTER CLASS BELOW:
 Copy this Router class below and put it in your app, rename routes and classes for your own, add more classes to it if necessary.
