Hello how can I transform a callback to a suspend fun?

interface Foo<T> {
  fun onSuccess(lis: (T?) -> Unit)
}

I'm trying to do something like this :

suspend fun getFoo(): Bar {
   suspendCoroutine<Bar?> { continuation -> 
     val listener = object : Foo<Bar?> {
        override fun onSuccess(lis: (Bar?) -> Unit) { }
     }
}

But I don't know how to return a Bar

Your onSuccess is probably not a callback, but a function to register a callback. I don't think it's expected that you create an instance of Foo yourself here. Could you please share the real-life names for those types? Coroutines aside, how is Foo supposed to be used with the callback approach?
