Does it support Singleton pattern???

[cattlelovegrass]

class HttpManager { static final HttpManager _instance = HttpManager._internal();

factory HttpManager() { return _instance; }

HttpManager._internal(); } if this code implements $Instance, Is it the same as usual?

You can use the dart_eval binding generator to automatically generate an $Instance wrapper that can do this
