SlotType class

插槽类型定义

Slot type definition for identifying and ordering player UI slots.

每个插槽类型由 key（唯一标识）和 defaultOrder（默认层级顺序）组成。 内置插槽使用预定义的常量，间距为 10，便于外部插入自定义插槽。

Each slot type consists of a key (unique identifier) and defaultOrder (default stacking order). Built-in slots use predefined constants with gaps of 10, making it easy to insert custom slots at any position.

内置插槽使用示例 / Built-in slot usage:

AliPlayerWidget(
  controller,
  slotBuilders: {
    SlotType.topBar: (context) => MyCustomTopBar(),
  },
)

自定义插槽使用示例 / Custom slot usage:

// 定义自定义插槽，order=35 自动落在 coverImage(30) 和 playControl(40) 之间
const watermark = SlotType('watermark', defaultOrder: 35);

AliPlayerWidget(
  controller,
  slotBuilders: {
    watermark: (context) => WatermarkWidget(),
  },
  // 按 defaultOrder 自动排序
)
