Is there a safe way to use combine() when you have a long list of Flows? I worry about the Flows and the param names becoming unsynced as the code is changed over time.

combine(
      stringFlow1,
      stringFlow2,
      intFlow1,
      intFlow2,
    ) { string2, string1, int2, int1 ->
     
    }

You can make lambda parameter types explicit:

combine(colors, sizes) { color: Color, size: Size -> ... }

I think he meant if the types are the same, so if you change the order of the parameters, the compiler would error

afaik there's no way. What we do is whenever possible, create intermediate flows combining just a few

You can also use inline (value) classes to wrap your primitive types and avoid type mismatch https://kotlinlang.org/docs/inline-classes.html
