@Entry 
@Component 
struct RatingTest { 
 @State isSeclet : boolean = false 
 build() { 
  Column(){ 
   Row(){ 
    Button('ddddd') 
   } 
   .width('100%') 
   .justifyContent(FlexAlign.Center) 
   .backgroundColor(Color.Red)//红色的是实际作用范围 
   .onClick(() => { 
    console.log('撒大苏打大苏打') 
   }) 
 
  } 
  .justifyContent(FlexAlign.Center) 
  .width('100%')
