is Array<> in compose stable?

[Matthew Feinberg]

Immutability isn't enforced for arrays, so there are a whole array (no pun intended) of possible hard-to-find bugs that could spring up if someone writes code that mutates the array. Personally, I'd prefer List<> for this sort of thing.

[谢朋刚]

so prefer ImmutableList ?

[Matthew Feinberg]

You could, but List<> is a read-only interface, so unless you're trying to cast it to other things, just List<> is probably what you want (it's what you get if you use listOf<>(...) for example.

Importantly List actually unfortunately still is not considered stable for compose’s sake. So either just use ImmutableList for now, or wait for strong skipping mode to be turned on where they will also start inferring List as stable

[Matthew Feinberg]

That's good to know, thank you!

[Matthew Feinberg]

(I don't normally pass List<> directly, and the classes that I use that wrap it are annotated with @Immutable, so I forgot about that)

[Stylianos Gakis]

Then don’t worry about it

[Matthew Feinberg]

Yeah, but I need to not give out wrong information here 😅 so it still matters.
