fortune_spin_wheel 0.1.2

A highly customizable Flutter spin wheel package for rewards, campaigns, games, and lucky draws.

Fortune Spin Wheel

[Fortune Spin Wheel Demo 1] [Fortune Spin Wheel Demo 2]

A reusable, highly customizable Flutter spin wheel for internal company apps.

Inspired by the supplied reward-wheel design, but built as a configurable package so each app can change:

• Number of segments
• Segment text/value
• Segment images or no images
• Segment colors
• Text style/alignment
• Wheel size
• Center button
• Marker/pointer design
• Outer ring
• Dividers
• Spin count / max spins
• Spin duration
• Winner animation
• Confetti
• Sound callbacks
• Custom winner overlay
• Custom callbacks
• Backend-selected winning index

Important reward-system note

For real rewards, the backend should decide the winning item/index. Do not rely on Random() in the Flutter UI for anything with monetary value.

The package accepts targetIndex, so your API can return the winner and the wheel can animate to that segment.

Basic usage

final controller = SpinWheelController();

SpinWheel(
  controller: controller,
  items: [
    SpinItem(label: '400 Points'),
    SpinItem(label: '₹100 Gift Card'),
    SpinItem(label: '100 Points'),
    SpinItem(label: 'Better Luck Next Time'),
  ],
  onWinner: (item, index) {
    debugPrint('Winner: ${item.label}');
  },
);

Then:

controller.spin(targetIndex: 1);

Image items

SpinItem(
  label: 'Amazon Gift Card',
  image: NetworkImage('https://example.com/amazon.png'),
)

Maximum spins

SpinWheelController(maxSpins: 3);

spin() returns false when the allowed spin count has been exhausted.

Sound

The package deliberately does not force an audio package on every host app.

Use callbacks:

SpinWheel(
  controller: controller,
  playSpinSound: () => audio.play(...),
  playWinSound: () => audio.play(...),
)

Custom marker

SpinWheel(
  marker: const SpinWheelMarker(
    type: SpinMarkerType.star,
  ),
)

Available marker types:

• triangle
• arrow
• star
• pin
• custom

Winner effect

SpinWheel(
  showConfetti: true,
  showWinnerOverlay: true,
  winnerOverlayBuilder: (context, item, index) {
    return MyWinnerDialog(item: item);
  },
)
