How to animate the opening block?

Question

React

There is a block with floating height. Initially, it is closed, when clicked, it opens, how can I animate the opening? If you know the height, then it's not a problem, Animating.timing is just right, but there is no height.

Answer 1

Usually this library is used to solve this problem react-native-collapsible

Answer 2

this work?

Answer 3

I implemented it with a height for a specific element, passed it through props.
Somehow it turned out to be adaptive when explicitly passing null or undefined, but I don’t remember anymore, it didn’t always work correctly, depending on whether the element is absolute.
