layout
Common
Modifier in Compose Ui
Creates a [LayoutModifier] that allows changing how the wrapped element is measured and laid out.
This is a convenience API of creating a custom [LayoutModifier] modifier, without having to create a class or an object that implements the [LayoutModifier] interface. The intrinsic measurements follow the default logic provided by the [LayoutModifier].
