通过代码动态创建的UI子节点默认layer为Default，但是通过UIPanel直接挂在场景上却为UI

string assetsName = $"Assets/Bundles/UI/MiniGame/StartGame";

var uiPackage = UIPackage.AddPackage(assetsName);

foreach (var dependency in uiPackage.dependencies)

{

    UIPackage.AddPackage($"Assets/Bundles/UI/MiniGame/{dependency["name"]}");

}

var panel = uiPackage.CreateObject("Panel");

GRoot.inst.AddChild(panel);
