Hi guys, hope you are all doing well.
What arw you using for lottie animations in compose multiplatform. I stumbled upon a couple of libraries, compottie and kottie? Which one would you recommend? Did you have issues with any of these?

[Andrew Watson]

I actually just went through the process of trying both of these libraries out! Some pros & cons to each:

Compottie
• Uses Lottie on Android and Skottie on iOS
• Both platforms support alpha transparency behind anim
• Can end up with incompatible animations (I did, but eventually got it working)
Kottie
• Uses Lottie both iOS and Android
• Alpha transparency behind anims only works with Android
• Seems to wider animation compatibility
TL;DR - if you don't need alpha transparency behind your anim use Kottie. Otherwise take your chances with Compottie. It's what I'm using right now and it's good

[Djuro]

By alpha transparency you mean the see-through effect?

[Andrew Watson]

yeah

[Andrew Watson]

Like being able to "see through" your anmiation

[Djuro]

Aha okay, dont need that at all honestly :D

[Andrew Watson]

FWIW on iOS it also uses a UIKitView

[Andrew Watson]

That may or may not matter; not quite sure what skottie does, but I do know lottie has done a lot for perf improvements lately

[Djuro]

I'm using compose multiplatform anyways, so it shouldnt really matter :D

[Djuro]

Thank you andrww

👍

@Andrew Watson Could you please tell me what do you use for managing your lottie file resoures, do you use compose multiplatform resources or something like that?

[Andrew Watson]

Kottie takes care of things for you, so long as the json is in the files directory. In compottie you have load the file and get the string yourself. I personally just hard-coded the animations as strings in my build

[Djuro]

I am doing it like that atm, but I think that approach is pretty bad tbh

[Djuro]

better have it somewhere in assets
