Hi all, can we use firebase analytic on a KMM project?

[mbonnin]

I think there is a third party lib...

Maybe this? https://firebaseopensource.com/projects/gitliveapp/firebase-kotlin-sdk/

Generally speaking, analytics calls consist of an event name and a map of key/value pairs. We usually just write a Kotlin interface to call from shared code and pass in a simple Swift implementation on app start. Taking a quick look at that firebase lib, I don’t think it has analytics.

@mbonnin thanks for sharing

@kpgalligan so you basically used expect/actual ? i think it’s the best option

[brabo-hi]

when logging error messages what event name/params do you usually use

[kpgalligan]

I rarely use expect/actual. Depends on the situation. I’d just have a function defined in common and pass in the implementation on app start. expect/actual is rigid and not useful in this case.

[kpgalligan]

So, for Firebase the call to log an event is this in Swift

class func logEvent(_ name: String, parameters: [String : Any]?)

[kpgalligan]

I assume similar on Android.

[kpgalligan]

I’d just have an init call in common code that takes a function as a param:

fun initAppStuff(logEvent: (String, Map<String, Any>)->Unit)

[kpgalligan]

Something like that. On iOS, call that in the AppDelegate (or the new equivalent thing I don’t remember). Similar thing on Android. Call in Application.onCreate. On both, have that function call the actual Firebase method.

I see, thanks for sharing
