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: [

            ],
        ),
    ),
),

Flat

Flat flatButton

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"),
            ],

NeoPopTiltedButton Attributes

Attribute Type Description
child Widget The child of the button
color Color? Color of the button
decoration NeoPopTiltedButtonDecoration? The decoration to paint the button. The color and decoration arguments cannot both be supplied, since it would potentially result in the decoration drawing over the background color. To supply a decoration with a color, use decoration.
buttonDepth double? The depth of the tilted button. default: 8.0
onTapUp VoidCallback? A callback triggered when a pointer that will trigger a tap with button has stopped contacting the screen
onTapDown VoidCallback? A callback triggered when a pointer that might cause a tap with button has contacted the screen
shadowDistance double? The maximum distance from the button at which the shadow is painted. default: 20
yPosFactor double? Factor that defines the floating positions of buttons and shadow along vertical-axis. default: 5
isFloating bool Whether the button is floating. default: false
floatingDuration Duration? The duration of the floating animation. One floating cycle i.e to-and-fro movement of the button and shadow accounts for two floating durations. default: Duration(milliseconds: 1500)
floatingDelay Duration? The delay between two floating cycles. default: Duration(milliseconds: 750)
tapDuration Duration? The duration of the animation when button is pressed or released. default: Duration(milliseconds: 100)
enabled bool Whether the button is enabled. default: true
