DatePickerTileSchema

@Serializable

@SerialName(value = "DatePicker")

data class DatePickerTileSchema(val id: String, val events: SerializableImmutableList<EventSchema>?, val style: StyleSchema, val searchableTerms: SerializableImmutableList<String>?, val visibility: TileSchema.Visibility, val expanded: Boolean, val selectedDate: String?, val enabled: Boolean, val kind: DatePickerTileSchema.Kind, val confirmLabel: String, val cancelLabel: String, val supportingText: String?, val state: DatePickerTileSchema.State) : TileSchema

Renders a read-only text field that opens a Material 3 DatePickerDialog when tapped. kind picks the field composable: Kind.FILLED → TextField, Kind.OUTLINED → OutlinedTextField. The field always shows a calendar_month leading icon, displays selectedDate (empty when null), forwards enabled and supportingText, and switches to Material's error styling when state is State.ERROR. Typing is impossible — the field is readOnly and its onValueChange is a no-op.

Dates are ISO strings. selectedDate is an ISO date (yyyy-MM-dd); the renderer converts it to/from epoch millis for the Compose DatePickerState.

Open state: expanded drives the dialog. Pressing the field dispatches a local DatePickerTileEvents.OnDatePickerToggle (holder flips expanded); confirming dispatches OnDateConfirmed (holder stores the date and closes); cancelling or dismissing dispatches OnDatePickerDismissRequest (holder closes). All of this is handled client-side, without a round trip to the server. The dialog's buttons are labelled with confirmLabel and cancelLabel, and the confirm button stays disabled until a date is picked, so confirming always yields a date.

Triggers dispatched:

OnDatePickerOpenEventTrigger — when the field is pressed while closed.
OnDateSelectedEventTrigger — when the confirm button is pressed; the ISO date string is passed as the event's incoming data.
OnDatePickerCloseEventTrigger — when the field is pressed while open, when the dialog is dismissed, when cancel is pressed, and also right after a confirm.

Value production: the holder exposes selectedDate under a caller-chosen key so GetData / EvaluateData events can read this picker by its id. When no date is selected it produces no entry at all.
