KStore 0.9.0 Help

Using List Store

KStore provides you with some convenient extensions to manage stores that contain lists.

Create a list store

listStoreOf is the same as storeOf, but defaults to empty list instead of null

val listStore: KStore<List<Pet>> = listStoreOf(file = "path/to/file")

Get values

val pets: List<Cat> = listStore.getOrEmpty() val pet: Cat = store.get(0)

or observe values

val pets: Flow<List<Cat>> = listStore.updatesOrEmpty

Add or remove elements

listStore.plus(cat) listStore.minus(cat)

Map elements

listStore.map { cat -> cat.copy(cat.age = cat.age + 1) } listStore.mapIndexed { index, cat -> cat.copy(cat.age = index) }
