FR:Possible to make Dynamic Links parameters dictionary public

[alihanaktay]

Feature proposal

• Firebase Component: Firebase Dynamic Links

In our use case we need to send some parameters(e.g. utm_ campaign, utm_medium etc.) to the backend for checking is any discount available for this campaign. In current developer's can't reach the dynamic links parameters even if received by app. Is it possible to make Dynamic links parameters public?

Also +1 for anything that can be set via console/api link creation to have public accessors via an instance of DynamicLink, just because i enjoy being lazy and would enjoy not parsing urls for already structured data.

let handled = DynamicLinks.dynamicLinks().handleUniversalLink(link) { fdl, error in
  guard let fdl = fdl, let url = fdl.url else { return }
   
  // 😍  😍 😍 😍
  let campaign: String? = fdl.utmCampaign
  let medium: String? = fdl.utmMedium
}
