Installation

Add neopop as a dependency in your pubspec.yaml file.

dependencies:
    neopop: ^1.0.2

NeoPopButton

NeoPopButton render 5 surfaces, top, left, right, bottom and center. NeoPopButton widget gives you mutliple configs that you can use for your widget.

Elevated

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"),
            ],
        ),
    ),
),

Flat

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"),
            ],
        ),
    ),
),

Shimmer

const NeoPopShimmer(
    shimmerColor: Colors.yellow,
    child: Padding(
        padding: const EdgeInsets.symmetric(horizontal: 100, vertical: 15),
        child: Text("Hello"),
    ),
),

Flat Strokes

To add border on a flat button, add border

NeoPopButton(
    color: const Color.fromRGBO(0, 0, 0, 1),
    buttonPosition: Position.center,
    onTapUp: () {},
    border: const Border.fromBorderSide(
        BorderSide(color: kBorderColorWhite, width: kButtonBorderWidth),
    ),
    child: Padding(
        padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 15),
        child: Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: const [
                Text("Pay Now", style: TextStyle(color: Colors.white)),
            ],
        ),
    ),
),

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

`isFloating`	`bool`	Whether the button is floating. `default: false`

`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)`
