        body: Center(
          child: ButtonPicker(
            minValue: 0,
            maxValue: 99,
            initialValue: 0,
            onChanged: (val) => print(val),
            step: 2.5,
            horizontal: false,
            loop: true,
            padding: 5.0,
            iconUp: Icons.keyboard_arrow_up,
            iconDown: Icons.keyboard_arrow_down,
            iconLeft: Icons.keyboard_arrow_left,
            iconRight: Icons.keyboard_arrow_right,
            iconUpRightColor: Colors.blue,
            iconDownLeftColor: Colors.blue,
            style: TextStyle(
              fontSize: 48.0,
              color: Colors.blue
            ),
          ),
        ),
      ),
    );
  }
}

• minValue [required] is the minimum value of the ButtonPicker.
• maxValue [required] is the maximum value of the ButtonPicker.
• initialValue [required] is the value displayed on load.
• onChanged [required] returns the current value.
• step defines how much the value should increase or decrease on tap.
• horizontal renders a horizontal ButtonPicker when set to true.
• loop lets the ButtonPicker count from the beginning when passing maxValue or from the end when passing minValue when set to true.
• padding defines the space between the buttons and the value.
• iconUp, iconDown, iconLeft and iconRight are the actual icons.
• iconUpRightColor is the color of the upper button when horizontal == false and the color of the right button when horizontal == true.
• iconDownLeftColor is the color of the lower button when horizontal == false and the color of the left button when horizontal == true.
• style is the TextStyle of the value.

Note: When both initialValue and step are integers, the value won't have any decimals.
