NeoPopButton render 5 surfaces, top, left, right, bottom and center.
NeoPopButton widget gives you mutliple configs that you can use for your widget.
NeoPopButton(
color: Colors.white,
onTapUp: () => HapticFeedback.vibrate(),
onTapDown: () => HapticFeedback.vibrate(),
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 20, vertical: 15),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text("Pay now"),
],
),
),
),
By specifying the buttonPosition as Position.center, NeoPOP will compute right and bottom surface's color according to color.
Top and left surface's color is computed w.r.t parentColor and grandparentColor
NeoPopButton(
color: Colors.white,
onTapUp: () => HapticFeedback.vibrate(),
onTapDown: () => HapticFeedback.vibrate(),
parentColor: Colors.transparent,
buttonPosition: Position.center,
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 15),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [
Text("Pay Now"),
],

),
),const NeoPopShimmer(
shimmerColor: Colors.yellow,
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 100, vertical: 15),
child: Text("Hello"),
),
),
To add border on a flat button, add border
NeoPopButton(
color: const Color.fromRGBO(0, 0, 0, 1),

onTapUp: () {},
border: const Border.fromBorderSide(
BorderSide(color: kBorderColorWhite, width: kButtonBorderWidth),
