Hello 👋 Whats the proper way to define required properties/configuration for a custom plugin? docs here show optional values with fallback to default -> https://ktor.io/docs/custom-plugins.html#configuration-file should I mark those as

lateinit

? or maybe by using

Delegates.notNull()

? or is there some more elegant way to do it?

I am not sure if the config has a handle for reporting these cases but otherwise it seems defining the fallback as

?: error("config is mandatory but was missing")

would be better than whatever funky errors lateinit or notNull produces

yeah its just I wish there was a way to communicate to user

if you install this plugin you need to configure those properties

(failure at build time - compiler would complain) vs failing at runtime with the info

Unfortunately, this isn’t possible because a plugin instantiates its configuration object and a user who configures the plugin can only mutate configuration object.
