defmodule Mob.Photos do
@moduledoc """
Photo / video library picker.
On iOS 14+ no permission is required (the picker itself is sandboxed).
On Android, `READ_MEDIA_IMAGES` / `READ_MEDIA_VIDEO` may be needed.
Results arrive as:
handle_info({:photos, :picked, items}, socket)
handle_info({:photos, :cancelled}, socket)
Each item in `items` is:
%{path: "/tmp/mob_pick_xxx.jpg", type: :image | :video,
width: 1920, height: 1080}
iOS: `PHPickerViewController`. Android: `PickMultipleVisualMedia`.
