defmodule Dala.Settings do

  @moduledoc """

  Persistent app settings (UserDefaults on iOS, SharedPreferences on Android).



  ## Examples



      # Get a setting value

      Dala.Settings.get("theme")



      # Set a setting value

      socket = Dala.Settings.set(socket, "theme", "dark")



      # Watch a key for changes (messages arrive via handle_info)

      socket = Dala.Settings.watch(socket, "theme")



  Incoming change messages are delivered to screens via `handle_info/2`:



      def handle_info({:settings, :changed, {key, value}}, socket) do

        # React to setting change

        {:noreply, socket}

      end
