onUnmount
onUnmount(
fn):void
Registers a lifecyle callback for when a molecule is released (unmounted).
This lifecycle will be called everytime this molecule that is used for a scope has been released. This helps provide an opportunity to cleanup or stop anything that is internally used.
For example, if your molecule is scoped by some UserScope
then onUnmount will be called for when “User A” and “User B”
scopes are released.
