Parameters

Name	Type	Default	Description
component	string	—	Component or hook name, used as the message prefix. Required.
message	string	—	What went wrong and how to fix it. Required.
condition	MaybeRefOrGetter<boolean>	true	Whether to warn. A plain boolean, a ref, or a getter all work. The first time it is true during a mount the warning fires once, and toggling it again in the same mount stays quiet.

Returns

Name	Type	Description
—	void	Nothing is returned. The watcher stops when the component or effect scope is disposed, and in a production build the function does nothing at all.
