CustomDialogController 如何脱离 @Component 初始化？更好的减少低耦合?

new DialogView().open()

let dialogController: CustomDialogController | null = null
@Component
export struct DialogView {
  open(): void {
    this.createDialog()?.open()
  }

  createDialog(): CustomDialogController {
    dialogController = new CustomDialogController({
      builder: CustomDialog(),
      autoCancel: true,
      alignment: DialogAlignment.Center,
      offset: { dx: 0, dy: -20 },
      customStyle: false,
      backgroundColor: 0xd9ffffff,
      cornerRadius: 10,
      gridCount: 6
    })
    return dialogController
  }

  build() {
  }
}
