Sortable components significantly increase render time

[MatiPl01]

Description

Sortable component (SortableFlex, SortableGrid) take much time to set up (many shared values, measurements, etc.). This can delay the initial screen render time significantly, which can be seen on the video below.

If possible, most of the setup logic should be delayed after the initial render is completed (e.g. the sortable component should render all its items in a relative layout without measuring them and calculating the absolute layout. Once all items are rendered and the transition to the screen is fished, sortable component providers can be set up).

I think that there is not much I can do. It seems that most of the time needed for render is not caused by logic I add to the sortable component. I am closing this for now and may consider improving the render time in the future.
