如何键入反应。具有静态属性的ComponentType?

我正在为next编写一个HOC组件。js页面,这个HOC需要接受具有特定 getInitialProps

我无法使用flow找到正确的键入方式:

const wrapComponent = (Component: React.ComponentType<*>) => {
    const original: Function = Component.getInitialProps;

    return class extends React.Component<*> {
        static async getInitialProps(ctx) {
            const props = await original(ctx);
            return {
                ...props,
                custom: 'a',
            };
        }

        render() {
            return <Component {...this.props} />;
        }
    }
}

我发现这个错误:

5:     const original: Function = Component.getInitialProps;
                                            ^ property `getInitialProps`. Property not found in
5:     const original: Function = Component.getInitialProps;
                                  ^ statics of React$Component
