CountDownUseCase

The CountDownUseCase class is used to manage the countdown logic and plate colors in the interpolated countdown widget. Below are the parameters that can be configured when creating an instance of this class.

Parameters

  • timerTextSize (Type: double, Default: 55): Font size of the timer text.

  • diameter (Type: double, Default: 204): Diameter of the countdown widget.

  • totalDuration (Type: Duration, Default: Duration(seconds: 30)): Total duration of the countdown.

  • stopAnimationOnTimeElapsed (Type: bool, Default: false): Whether to stop the animation when time reaches zero.

  • plateShape (Type: BoxShape, Default: BoxShape.circle): Shape of the countdown widget plates.

  • callBackOnEverySecondConsumed (Type: Function(int secondsConsumed)?, Default: null): A callback function that will be called every second during the countdown. It receives the total seconds consumed as a parameter.

  • outerPlateColorRange (Type: ColorRangeModel, Required): Color range for the outer plate.

  • innerPlateColorRange (Type: ColorRangeModel, Required): Color range for the inner plate.

Example

CountDownUseCase useCase = CountDownUseCase(
  timerTextSize: 55,
  diameter: 204,
  totalDuration: Duration(seconds: 30),
  stopAnimationOnTimeElapsed: false,
  plateShape: BoxShape.circle,
  callBackOnEverySecondConsumed: (int secondsConsumed) {
    print('Seconds Consumed: $secondsConsumed');
  },
  outerPlateColorRange: ColorRangeModel(
    firstColor: Colors.green,
    midColor: Colors.yellow,
    lastColor: Colors.red,
  ),
  innerPlateColorRange: ColorRangeModel(
    firstColor: Colors.blue,
