Fragment Arguments

Although Mavericks, doesn't have to be used with Fragments, it has some helpers in case it is.

Setting Mavericks Fragment arguments

When creating a Fragment:

1. Create a Parcelable or Serializable object
2. Set the Fragment arguments to yourArgs.asMavericksArgs()

val fragment = YourFragment()
fragment.arguments = yourArgs.asMavericksArgs()

Retrieving your arguments in your Fragment

Create a property in your fragment:

private val args: YourArgsType by args()

That's it!

Using Fragment args in the initial value for MavericksState

Create a secondary constructor that has 1 parameter of the same type as your Fragment arguments. Mavericks will automatically get the arguments off your Fragment and call this constructor with them when creating your State.

data class MyState(
  val itemId: String,
  val item: Async<Item> = Uninitialized
) : MavericksState {
  constructor(args: YourArgs) : this(args.itemId)
}
