buildSlot static method

Widget buildSlot({ required AliPlayerWidget widget, required SlotType slotType, required Widget defaultBuilder(BuildContext context), required BuildContext context, required AliPlayerWidgetController controller, })

构建插槽或默认组件

Build slot widget or default widget

controller 播放器控制器，传递给 slotBuilder 以支持在全屏模式下正确控制播放器

支持两种 slotBuilder 签名以保持向后兼容：

• Widget Function(BuildContext) - 旧版本（已废弃）
• Widget Function(BuildContext, AliPlayerWidgetController) - 新版本（推荐）

Implementation

static Widget buildSlot({
  required AliPlayerWidget widget,
  required SlotType slotType,
  required Widget Function(BuildContext context) defaultBuilder,
  required BuildContext context,
  required AliPlayerWidgetController controller,
}) {
  final slotBuilders = widget.slotBuilders;

  // 如果插槽构建器为null，则不显示该插槽
  if (slotBuilders.containsKey(slotType) && slotBuilders[slotType] == null) {
    return const SizedBox.shrink();
  }

  // 如果插槽构建器不为null，则使用自定义构建器，否则使用默认构建器
  final slotBuilder = slotBuilders[slotType];
  if (slotBuilder != null) {
    // 检测函数签名以支持向后兼容
    // 支持旧版 SlotWidgetBuilder (单参数) 和新版 SlotWidgetBuilderWithController (双参数)
    return _callSlotBuilder(slotBuilder, context, controller);
  }
  return defaultBuilder(context);
}
