HarmonyOS Toggle组件onChange方法手动触发

示例如下：

@Entry
@Component
struct TogglePage {
  @State flag: boolean = false;

  build() {
    Column() {
      Toggle({ type: ToggleType.Switch, isOn: true })
        .selectedColor('#007DFF')
        .switchPointColor('#FFFFFF')
        .onChange((isOn: boolean) => {
          if(this.flag) {
            console.info('Component status:' + isOn)
            this.flag = false
          }
        })
        .onClick(()=> {
          this.flag = true
        })
    }
  }
}
