reset method

void reset ()

Sets the controller's value to lowerBound, stopping the animation (if in progress), and resetting to its beginning point, or dismissed state.

The most recently returned TickerFuture, if any, is marked as having been canceled, meaning the future never completes and its TickerFuture.orCancel derivative future completes with a TickerCanceled error.

See also:

  • value, which can be explicitly set to a specific value as desired.
  • forward, which starts the animation in the forward direction.
  • stop, which aborts the animation without changing its value or status and without dispatching any notifications other than completing or canceling the TickerFuture.

Implementation 

void reset() {
  value = lowerBound;
}
