A modern programming language that makes developers happier.

kotlinlang

Opening some samples that exist online, Fleet seems to somehow magically pick up how to run the Android and the iOS applications, but they don't always look present in the file which stores the run configurations. Is it because for "default" cases (whatever that may be) it picks it up without the need for the configuration file?
I have found that a bit confusing in general, is this how it works right now? Am I misunderstanding something?
