How to use dependecy injection in flutter? -- [Question Asked]

Query asked by user

I wan to use di. in flutter and I add this https://pub.dartlang.org/packages/di packages my project and I started to read this https://webdev.dartlang.org/angular/guide/dependency-injection article, but I don’t fully understand.

So it’s ok:
use @Injectable() annotation on services class(e.g: MyServices), but how to inject other class?
For example I would like to similar:

class MyClass{
   //some variable
   var asd = MyService.asd; //need inject var.
                            //maybe use injector.get(MyService).asd; 
                            //but how add injector? (I don't add across constructor)

   MyService.oneMethod;//need inject method
}

main(){
    var injector = new ModuleInjector([new Module()
       ..bind(MyService)
    ]);
}

The point is, I don’t want to use a constructor. I want to directly use injector. This is possible in flutter/dart?

Answer we found from sources

Angulars DI package can’t be used independent of Angular.

The di package is quite outdated and depends on dart:mirrors which isn’t available in Flutter

There seems to be a new DI package work in progress which is supposed to replace Angulars built-in DI and should also be useable standalone in Flutter or server-side applications, but there is no pre-release or source code available yet.

update

The announced DI package was delayed indefinitely.
