问题描述
使用Typescript的tsx开发,组件中使用任何除了children的属性时,tslint都会报错。

export default class Test extends Component {
  static defaultProps = {
    xxx: '',
  }
  render() {
    return <View>{this.props.xxx}</View>
  }
}

现在解决办法是

const { xxx } = this.props as any
return <View>{xxx}</View>

期望行为
期望tslint能不报错

报错信息
[ts] 类型“Readonly<{}> & Readonly<{ children?: any; }>”上不存在属性“xxx”。
