📱UiState

Example of an UiState for a Dashboard

data class DashboardUiState(
    override val action: Consumable<DashboardUiAction>? = null,
    val state: ContentState,
) : Actionable<DashboardUiAction> {

    sealed interface ContentState {
        data object Loading : ContentState
        data object Error : ContentState
        data class Content(
            val title: String,
            val description: String
        ) : ContentState
    }
}

Note that DashboardUiState implements the Actionable interface for one-time actions sent from the ViewModel to the Fragment, like showing a Dialog or a Snackbar, or navigating to another Screen.

Here's how a child of MVIViewModel would send an UiAction to the Screen via its UiState:

private fun onClickOnNext() {
    update { copy(action = Consumable(DashboardUiAction.NavigateToNext)) }
}
