Hello! I'm trying to add background image for card in a list and card has a favourite toggle. When favourite state changing the composable function re-drawing the card and background re-drawing again. Is it possible to avoid re-drawing background image every time?

how are you drawing the image?

I tried to use DrawImage

loadImageResource(imageResId).resource.resource?.let {
    DrawImage(image = it)
}

or

DrawImage(imageResource(imageResId))

to add draw caches you need to wrap Image into RepaintBoundary. this basically first draws Image into RenderNode and then reuses this rendernode

Thank you for your answer, it was my fault I used ModelList with immutable data and created copy of object when pressed favourite button
