EmergentButton class

A Emergent Button

When pressed, it will fire a call to its EmergentButtonClickListener click parameter The animation starts from style.depth (or theme.depth is not defined in the style) @see EmergentStyle

And finished to minDistance, in duration (time)

You can force the pressed state using pressed

true : forced as pressed
false : forced as unpressed
null : can be pressed by user

It takes a padding, default EdgeInsets.symmetric(horizontal: 8, vertical: 4)`

It takes a EmergentStyle @see Emergent

 EmergentButton(
         onClick: () {
           setState(() {
              ...
           });
         },
         boxShape: EmergentBoxShape.roundRect(BorderRadius.circular(12)),
         style: EmergentStyle(
           shape: EmergentShape.flat,
         ),
         child: ...
 )
