Helper for WidgetsBinding.It is a easy way to use WidgetsBinding, for example: Get the size of a widget after the widget is rendered.

Getting Started

Install

add

    binding_helper:

to your pubspec.yaml

Get the size of the widget

Using GetRectMinxin


class MyState extends State<MyWidget> width GetRectMinxin<MyWidget>{

    // The rect includs size and position of the widget
    @override
    void onGetRect(Rect rect) {
        ...you code
    }

}

Using RectProvider


 new RectProvider(child: myWidget,onGetRect: (Rect rect){
            /// rect is the `Rect` of myWidet
          _rect = rect;

},)

More easy way to use WidgetsBinding is coming soon.
