Usage of "await" w/o an assignment causes the error in the runtime

[antonmoiseev]

If I use await and don't save the result of async operation in a variable, AngularDart throws an error in the runtime.

Example:

@Component(...)
class MyComponent {
  MyService _myService;

  MyComponent(this._myService);

    method() async {
      await _myService.doAsyncOperation();
    }
}

This throws following error: Type 'MyComponent' not found in generated typeFactory maps. Is the type's constructor injectable and annotated for injection?

When I save the result in a variable, the code works fine:

final _ = await _myService.doAsyncOperation();
