Slot Machine Roller

The easiest way to control slot machine.
You just use setState to pass to target parameter to deterministic value to stop rolling.
Otherwise pass null to target parameter to start rolling until no null.

Here is the demo page.

Features

• Easy way to start/stop rolling.
• Customized build items in roller.
• Deterministic value to stop in anytime.
• The rolling animation involved damping.
• Enable rolling delay at start time.
• With up or down rolling direction.

Getting started

flutter pub add slot_machine_roller

Usage

You can see example for more details.

SlotMachineRoller(
    height: 170,
    width: 300,
    delay: Duration(seconds: 1)
    reverse: true,
    target: target,
    itemBuilder: (e) => Container(
        margin: EdgeInsets.symmetric(vertical: 10),
        height: 150,
        width: 150,
        alignment: Alignment.center,
        decoration: BoxDecoration(
            shape: BoxShape.circle, color: Colors.blue),
        child: Text(
            '$e',
            style: Theme.of(context)
                .primaryTextTheme
                .headlineLarge,
        ),
    )),
// To stop roller and suspend 4
setState(){
    target = 4;
}
// To start rolling until deterministic target
setState(){
    target = null; 
}

Please Note the height of item should as equal as the height of SlotMachineRoller. Because we expect the view only one item in roller.
