SlicePipe角函数

Question

我正在尝试创建要排序的切片，但该切片无法与setCurrentPage（ts）通信

html

*ngFor="let item of galleries | searchGalleries : searchValue | slice:start:end; trackBy:item?.id"

ts

  setCurrentPage(page = 0) {
    this.limit = 3;
    this.currentPage = page;
   this.start = this.currentPage * this.limit;
    this.end = this.start + 3;
  }
