stop method
void
stop()
Cancel: the fx drops, the base was never touched, and the clock is at zero again — nothing plays, so a shader pass drawn by the clock shows the authored moment too.
Implementation
void stop() {
playable
..clearFx()
..clock.value = Duration.zero;
_position = Duration.zero;
_remaining = 0;
_end(MotionPlayerStatus.idle);
}
