feat(core): Add type information to injector.get() (#13785) - Introduce `InjectionToken<T>` which is a parameterized and type-safe version of `OpaqueToken`. DEPRECATION: - `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead. - `Injector.get(token: any, notFoundValue?: any): any` is now deprecated use the same method which is now overloaded as `Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`. Migration - Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it. - Migrate your code to only use `Type<?>` or `InjectionToken<?>` as injection tokens. Using other tokens will not be supported in the future. BREAKING CHANGE: - Because `injector.get()` is now parameterize it is possible that code which used to work no longer type checks. Example would be if one injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`. The injection instance will be that of `MockFoo` but the type will be `Foo` instead of `any` as in the past. This means that it was possible to call a method on `MockFoo` in the past which now will fail type check. See this example: ``` class Foo {} class MockFoo extends Foo { setupMock(); } var PROVIDERS = [ {provide: Foo, useClass: MockFoo} ]; ... function myTest(injector: Injector) { var foo = injector.get(Foo); // This line used to work since `foo` used to be `any` before this // change, it will now be `Foo`, and `Foo` does not have `setUpMock()`. // The fix is to downcast: `injector.get(Foo) as MockFoo`. foo.setUpMock(); } ``` PR Close #13785
