How to export dotween

[Yin Yuewei]

I tried to export it, but some exported classes are empty(sequence).

public class Lua_DG_Tweening_Sequence : LuaObject {
[UnityEngine.Scripting.Preserve]
static public void reg(IntPtr l) {
getTypeTable(l,"DG.Tweening.Sequence");
createTypeMetatable(l,null, typeof(DG.Tweening.Sequence),typeof(DG.Tweening.Tween));
}
}
