Spark DSL for declarative Dala screens.

Defines attributes for screen state and UI component entities that mirror Dala.Ui.Widgets one-to-one. Container entities (column, row, box, scroll, modal, pressable, safe_area) support nested children via Spark's entities + recursive_as mechanism.

Usage

defmodule MyApp.CounterScreen do
  use Dala.Spark.Dsl

  dala do
    attribute :count, :integer, default: 0

    screen name: :counter do
      column padding: :space_md, gap: :space_sm do
        text "Count: @count", text_size: :xl
        button "Increment", on_tap: :increment
      end
    end
  end

  def handle_event(:increment, _params, socket) do
    {:noreply, Dala.Socket.assign(socket, :count, socket.assigns.count + 1)}
  end
end
