HarmonyOS 鸿蒙Next升级新deveco-studio版后ResourceStr和any类型都不好用了

import router from '@ohos.router'
import json from '@ohos.util.json'

@Component
export struct Header{
  private   title: ResourceStr
  @State params: any   = router.getParams()
  build(){
    // 标题部分
    Row({space: 5}){
      Image($r('app.media.ic_public_back'))
        .width(30)
        .onClick(() => {
          // 返回前的警告
          /* router.showAlertBeforeBackPage({
             message: '支付还未完成，确定要返回吗？'
           })*/

          // 返回上一页
          router.back()
        })
      if(this.params && this.title){
        Text(this.params.id + '.' + this.title)
          .fontSize(28)
          .fontWeight(FontWeight.Bold)
      }
      Blank()
      Image($r('app.media.ic_public_refresh'))
        .width(30)
    }
    .width('98%')
    .height(30)
  }
}

在升级新版的deveco-studio-5.0.3.600.exe后现上面的两行代码会报错：

private  title: ResourceStr 
@State params: any  = router.getParams()

1. title 这种赋予类型会报错：Property ‘title’ has no initializer and is not definitely assigned in the constructor. <ArkTSCheck>

2. params 这种赋予类型会报错：Use explicit types instead of “any”, “unknown” (arkts-no-any-unknown) <ArkTSCheck>

在deveco-studio-5.0.3.900.exe 中编译是不过通过的。
