Inherited injectable properties are not resolved.

[bobjackman]

injector.resolveInjections() uses classMirror.declarations to obtain a list of all injectable variables on a class. However, classMirror.declarations doesn't include inherited properties as such, the following injection is never resolved:

class Foo extends Bar {
  Foo():super();
}

class Bar {
  @inject Zap myInjectedProperty;

  Bar() {
    // setup
  }
}

var bar = new Bar();
print(bar.myInjectedProperty); // <<-- instance of Zap

var foo = new Foo();
print(foo.myInjectedProperty); // <<-- null

Should be fixed by pull request. @MikeMitterer previously asked if he could take over this project as I have little time.
