The current progress value.

current?: undefined | number;

E.g. setting to 4 with a max value of 10 would set a fixed progress bar on the notification at 40% complete.

If true, overrides the max and current values and displays an unknown progress style. Useful when you have no knowledge of a tasks completion state.

indeterminate?: undefined | false | true;

Defaults to false.

The maximum progress number. E.g 10.

max?: undefined | number;

Must be greater than the current value.
