было бы круто, если бы тип был:
val profileState: Loading.State<Profile>
Для этого нужно сделать утилитную функцию, которая преобразует StateFlow в композовскую стейт-переменную.
| when (profileState) { | ||
| is Loading.State.Data -> { | ||
| val profileData = (profileState as Loading.State.Data<Profile>).data | ||
| val isRefreshing = (profileState as Loading.State.Data<Profile>).refreshing |

Хотелось бы использовать тут смарт-касты. Это получится, если исправить тип profileState в ProfileComponent и добавить промежуточную переменную.
when (val profileState = component.profileState) {
}

вот тут написать и использовать утилиту:
override val profileState by profileLoading.stateFlow.collectAsState(coroutineScope)

давай, организуем зависимости так же, как остальные сделаны

Давай, уберем возможность задавать startState. Всегда будем брать начальное значение из this.value
| import kotlinx.coroutines.launch | ||
|
|

| fun <T> StateFlow<T>.toComposeState(coroutineScope: CoroutineScope, startState: T = this.value): State<T> { | ||
| val profileState: MutableState<T> = mutableStateOf(startState) |
