Skottie Expression Support

[John Rolewicz]

Hello! I've been working with Skottie through Canvaskit-WASM, and am I bit confused with Skottie's support of expression. When compiled in Canvaskit, it appears that expressions are entirely unsupported, correct?

However, reading through this discussion group, I've found various references to Expressions being supported. Like here for example: https://groups.google.com/g/skia-discuss/c/BY7FdpmRaJ0/m/bJCeoeKkBgAJ

Is this only with some sort of custom Expression evaluator? Or available when skottie is used directly but not in the Canvaskit compilation?

Any clarification on this would be great. Thanks!

Yeah, pretty much: we don't offer a built-in ExpressionEvaluator, and clients that need expressions support must provide their own.

(as a workaround, when feasible, designers can also convert expressions to keyframes when exporting with Bodymovin)

 

Any clarification on this would be great. Thanks!
