What is the difference between Modifier.height and Modifier.requiredHeight ?

[Geert]

Before we had height and preferredHeight. Which were renamed to requiredHeight (height) and height (preferredHeight)

[André Kindwall]

This code and image illustrates the difference pretty well

Column(Modifier.width(50.dp).background(Color.Red)) {
    Box(Modifier.size(60.dp).background(Color.Green))
    Box(Modifier.requiredSize(60.dp).background(Color.Blue))
}

@Rafs you can check for the javadoc here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]/androidx/compose/foundation/layout/Size.kt;l=1?q=Size.kt&sq=

height

Declare the preferred height of the content to be exactly heightdp. The incoming measurement Constraints may override this value, forcing the content to be either smaller or larger.

requiredHeight

Declare the height of the content to be exactly [height]dp. The incoming measurement

[Constraints] will not override this value.

height is something which can change if the parent composable height becomes less than defined height

whereas requiredHeight doesn't change irrespective of parent composable's height , view will go outside the border

Thank you all for your responses.
