HarmonyOS @Builder 按引用传递参数编译错误？

Question

如题：HarmonyOS @Builder 按引用传递参数编译错误？

Answer 1

问题场景

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} `)
  }

参考代码：

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