some probs

[mikes222]

1. why do you force the child parameter? seems it is not really necessary.
2. I suggest to assert required params, e.g. FabCircularMenu(...) : assert(child != null), assert(options != null && options.length > 0);
3. If you want to provide this code as a library you need to move it to the lib/src folder and provide a dart file with export statements. See other libs. Currently I am unable to use your code as a lib. I rather copied the source code into my own repository instead.
4. Please add a dispose method:

    @override
    void dispose() {
      controller?.dispose();
      super.dispose();
    }

5. I still struggle when using 4 icons. In closed state the middle icons 1 and 2 are shown in the right-bottom corner beneath the fab.

You may find the problem, I don't currently.

6. Seems it is not allowed to init the controller twice. Move that initialization to the initState() method instead:

  @override
  void initState() {
    super.initState();
    controller = AnimationController(duration: widget.animationDuration, vsync: this);
  }

Thank you a lot for your feedback. This is my first package so i'm still learning.
I will take a look asap.

Beautiful widget. You must NOT initialize controller in the didChangeDependenciesMethod() but instead initialize it in the initState(). Right now I am having a problem when I open a new screen using navigator e.g

void _navigateToTreatment(BuildContext context) { Navigator.of(context).push( MaterialPageRoute( builder: (context) => TreatmentFormPage(), ) ); }

I've got this error message:

_FabCircularMenuState is a SingleTickerProviderStateMixin but multiple tickers were created.

and its because of the re-assigment of the controller in the didChangeDependenciesMethod().

Plus, it will be interesting exposing the method to reverse the animation manually.

Thanks, and good work!

Has a solution to the aforementioned issue been found?

Ok, i fixed the issue found by @spiralni, added an assertion and a dispose method. The child is still required because you are supposed to use this widget as a container, not as a Scaffold's floatingActionButton because if you do that, you end up with a margin around the circle.
