reverse abstract method

TickerFuture reverse({
  1. double? from,
})

Starts running this animation in reverse (towards the beginning).

  • from: Optional starting point. If omitted, continues from current value.

Ensures:

  • Returns a TickerFuture completing when reverse animation reaches lowerBound.
  • Dormancy Invariant: When dormant (no active VSYNC attached), the motion intention is staged and immediately returns a completed TickerFuture to guarantee the zero-leak Subscriber-driven Inactive Dormancy invariant and prevent orphaned async suspension leaks. When an active VSYNC is attached, the staged motion seamlessly resumes.

Implementation

TickerFuture reverse({double? from});
