buildOverlaysSlot static method

List<Widget> buildOverlaysSlot({ required AliPlayerWidget widget, required Widget defaultBuilder(BuildContext context), required BuildContext context, required AliPlayerWidgetController controller, })

构建浮层插槽

Build overlays slot widgets

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 List<Widget> buildOverlaysSlot({
  required AliPlayerWidget widget,
  required Widget Function(BuildContext context) defaultBuilder,
  required BuildContext context,
  required AliPlayerWidgetController controller,
}) {
  const slotType = SlotType.overlays;
  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 <Widget>[];
  }

  // 如果插槽构建器不为null，则使用自定义构建器
  final slotBuilder = slotBuilders[slotType];
  if (slotBuilder != null) {
    return [_callSlotBuilder(slotBuilder, context, controller)];
  }

  // 回退到默认的overlays参数（向后兼容）
  return widget.overlays;
}
