在HarmonyOS NEXT开发中@Builder 按引用传递参数编译错误？编译提示：Object literals cannot be used as type declarations (ArkTS-no-obj-literals-as-types) <ArkTSCheck>
代码：

@Builder overBuilder($$: { paramA1: string }) { 
  Row() { 
    Text(`UseStateVarByReference: ${$$.paramA1} `) 
  }

具体参考代码：

class Tmp{ 
  paramA1:string = ‘’ 
} 
@Builder function overBuilder($$ : Tmp) { 
  Text($$.params) 
    .width(400) 
    .height(50) 
    .backgroundColor(Color.Blue) 
}
