  }
}

选项

该规则无需配置额外选项。

正例

@Entry  
@Component  
struct MyComponent {  
  @State children: number[] = Array.from(Array<number>(900), (v, k) => k);  
  
  build() {  
    Scroll() {  
      Grid() {  
        ForEach(this.children, (item: Number[]) => {  
          GridItem() {  
            Text(item.toString())  
          }.backgroundColor(Color.Yellow)  
        }, (item: string) => item)  
      }  
      .columnsTemplate('1fr 1fr 1fr 1fr')  
      .columnsGap(0)  
      .rowsGap(0)  
      .size({ width: "100%", height: "100%" })  
    }  
  }  
}

反例

@Entry
@Component
struct MyComponent {
    @State children: number[] = Array.from(Array<number>(900), (v, k) => k);
    
    build() {
      Scroll() {
      Grid() {
        ForEach(this.children, (item: Number[]) => {
          GridItem() {
            // 冗余Stack
            Stack() {  
              Stack() {  
                Stack() {  
                  Text(item.toString())  
                }.size({ width: "100%"})  
              }.backgroundColor(Color.Yellow)  
            }.backgroundColor(Color.Pink)  
          }  
        }, (item: string) => item)  
      }  
      .columnsTemplate('1fr 1fr 1fr 1fr')  
      .columnsGap(0)  
      .rowsGap(0)  
      .size({ width: "100%", height: "100%" })  
    }  
  }  
}
