I am new to both Kotlin and Compose. Using some online guides I have been able to create some very simple UIs. I now have a problem that one of my UIs will not recompose when I use a property of a class within a composable. Below is my code. I create a class that has an INT property which is initialized to 3 and a method that will increase the property’s value. I am using the property value in the text of a button.

I have a LazyRow with several cells, and it tracks the item currently centered on the screen. The issue is that I’m using a state to track this center item, and each time the state updates, it triggers a recomposition. I noticed in the layout inspector that the cells in the LazyRow are continuously updating as I scroll left or right. This doesn’t happen if I comment out the state tracking. My question is: how can I avoid these unnecessary recompositions?

I’m learning Jetpack Compose and created a simple example to understand state management. I have a button that updates a width variable, and I want to calculate a size based on the width and height variables. However, the size variable is not updating as expected when width changes.

In my project from time to time I have error "Unsupported concurrent change during composition" -> This is probably caused by updating a State object from different threads at the same time.
I’m trying to figure it out why this could happen.

I have a screen in which users can see recommendations saved by them from different categories with filter buttons above implemented with the help of FlowRow:
