Fire custom events on route open / close

[subzero911]

Idea is taken from GetX. It has "Bindings". It can register dependencies on route open and unregister on route close. I'm not the fan of GetX, but I like the particular idea. Instead of having the bloated "get_it registrar", it's better to bind dependencies only to those screens which actually need it. And on route close it will be disposed, saving some RAM...

AutoRoute(
        page: BookListPage(),
        onInit: () => GetIt.I.registerSingleton<IBookController>(BookController());
        onDispose: () => GetIt.I.unregister<IBookController>(disposingFunction: (controller) => controller.dispose());
),

It's clean - you can open the routes.dart file and easily figure out, which screen uses dependencies. And it gives you scopes - this controller could be read from all the child routes. Moreover, with such callbacks you can fire any custom events, not only GetIt.

I proposed the same thing for go_router, https://github.com/flutter/flutter/issues/99113, they liked the idea but didn't make it yet (issue hangs open since February).

Hello @subzero911 I really love the idea, but in my case I can't just pass a callback function they way you proposed because here we're in the static realm. I'll try to figure something out thu

I achieve what you want by creating a listener to the router context. context.router.addListener(checkBeingActivatedRoute);

  Future<void> checkBeingActivatedRoute() async {
    final activeRoute =
        RoutesCore.retrieveContextListenerBeingActivatedRoute(context);
    switch(activeRoute){
    ....
    }
  }
