Hmm, I must be missing something obvious. The prop is undefined in the child component. This is my parent component. The log statement prints out the webUser's properties.

Route {
   path = "/campaigns"
   element = Campaigns.create {
      webUser
   }
   console.log("web user ->>> $webUser")
}

My child is set up like this and webUser is undefined....

external interface CampaignWebUserProps: Props {
    var webUser: WebUser
}

val Campaigns = FC<CampaignWebUserProps> {props ->

    val webUser by useState(props.webUser)
...
}

Am I missing something obvious?

If user data is common - it’s preferrable to use React

Context

instead

Ok, I'll read up on

Context

right now

I also just realize I can handle "injecting" bearer and dealing with refresh automagically with Ktor client so I won't need to do this (above) much longer. But I'm sure I'll want to pass props from parent to child sometime.

In next version it will be possible to use

ComponentType

instead
