Enhanced enum features for `AnimationStatus` #147801

nate-thegrate · 2024-05-03T19:35:22Z

Based on issue #147799, this pull request adds two AnimationStatus getters.

bool get isRunning => switch (this) {
  forward   || reverse   => true,
  completed || dismissed => false,
};

bool get aimedForward => switch (this) {
  forward || completed => true,
  reverse || dismissed => false,
};

I also added a .toggle() method for animation controllers that makes use of aimedForward.

+    controller.dispose();
+


I noticed that a controller was being reassigned here without a .dispose() call, so I added this as well.

+  bool get aimedForward => switch (this) {


I am not super in love with this name. I wish I had a better suggestion...

me too 🥲

I asked gemini, it came up with the very explicit isForwardOrCompleted name. Still not great, I like it slightly better then aimedForward, though.

I'm good with that!

+  /// 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.
+  TickerFuture toggle({ double? from }) {


Can you document the parameter?

Sure can!

I copied the documentation over from the forward/reverse functions, so I'll document the parameter for those as well.

… aimed-forward

LGTM

PR #147801 introduced some convenient `AnimationStatus` getters, but I just realized that `AnimationController` now has 2 getters for the same thing: `isAnimating` and `isRunning`. The intent of this pull request is to correct that mistake, and implement the getters in the appropriate places.
