I am trying to set an array of MovesNavigatorElement - which is a class I've defined - as a property of my @Composable but it does not compile : more in thread

[loloof64]

This is the sealed class MovesNavigatorElement

This is the code which does not compile.

Use = instead of by

Thank you very much. The compilation has gone. 😃 Now I am facing a different kind of error.

[Adam Powell]

Property delegation is the preferred convention for mutableStateOf because MutableState<T> is essentially a collection of exactly one element and explicitly referring to its .value property is cumbersome/noisy. Other snapshot collection types are used as usual elsewhere.

[loloof64]

Thank you, I understand. Also, is using a SnpashotMutableList the best way to handle a mutable array of items, in order to save them as a property of Composable, like I'm trying ? Or can I do simpler ?

[loloof64]

Finally found that the snapshot can be converted with .toTypedArray() .

[Adam Powell]

If composition is either a producer or consumer of mutations to this list, a snapshot list is probably the simplest solution.

Thank you. 😃 I think I've understood. In my current use case, I'm not particularly having Reactive Programming in mind
