Alignment Rect for Lottie Animations

[lucab-spotify]

I have a question.

What is the best way to have alignment rects in Lottie Animations?

My use case is that I need to manage toogle states with lottie animations in a similar fashion to the heart icon toogle in lottie-ios README file

What I need is a way to know what is the alignment rect that is meant to be used to align the lottie animations.

For example if I'm showing this animation inside a button icon that shows content in a 44x44 points container I want that 44x44 to match the following alignment rect:

where the heart is the final state of the toogle animations.

Is there a way of achieve this? Am I thinking about this problem from the right angle.

Which Version of Lottie are you using?

Lottie 4.4.2
