ComponentDefaultKey

@Stable

class ComponentDefaultKey<V : Any>

An identity key naming an independent part of a scoped cascade of inheritable modifier declarations.

Keys compare by identity (===). name is used for diagnostics, validation failures and toString; two keys with the same name remain independent. The type parameter V is the type of value this key expects, which must be non-nullable (null is reserved by provides for removing this key from a nested subtree).
