I have a variable defined like

val faceConditionsChecker by remember {
        mutableStateOf(
            FaceConditionsChecker {
                faceFrameRect
            }
        )
    }

Where faceFrameRect is a parameter of the composable function. I pass it via lambda to the class FaceConditionsChecker using it as val frameProvider: () -> RectF. Will the value of faceFrameRect when the lambda is called always correspond to the actual value of the parameter faceFrameRect ? If not how could I recreate FaceConditionsChecker on parameter change?

remember has no way to know that your function recomposed with a different faceFrameRect value to re-execute the lambda body. to fix this add faceFrameRect as a key to remember

But then I would ask if you really need to have that in a state object, or even remembered, at all

Thanks, guys! I really missed the key parameter or the remember . And it really makes sense to refactor this, because actually FaceConditionsChecker is stateless and I can replace it by a static function.
