如何正确定义样式组件的引用（React.RefObject<StyledComponentClass>）（对于 TypeScript）？

如何正确定义样式组件的引用？

我编写了以下测试代码。这是一个精炼的代码，与前一个 (How to correctly define a reference (React.RefObject) for styled-components (for TypeScript)?) 不同。添加了引用类型StyledComponentClass< {}, any>。

import React, {Component, RefObject, ReactNode} from 'react';
import styled, {StyledComponentClass} from 'styled-components';

type TModalShadowContainer = StyledComponentClass<{}, any>;

const ModalShadowContainer: TModalShadowContainer = styled.div` 
    background-color: black;
`;

export default class Modal extends Component {

    private readonly modalRef: RefObject<TModalShadowContainer>;

    constructor(props: {}) {
        super(props);
        this.modalRef = React.createRef<TModalShadowContainer>();
    }

    public render(): ReactNode {
        return (
            <ModalShadowContainer ref={this.modalRef}>
                {this.props.children}
            </ModalShadowContainer>
        );
    }

}

该行出现错误：

<ModalShadowContainer ref={this.modalRef}>

错误文本：

Type 'RefObject<StyledComponentClass<{}, {}, {}>>' is not assignable to type 'string | ((instance: Component<{ as?: string | ComponentClass<any, any> | StatelessComponent<any> | undefined; theme?: {} | undefined; }, any, any> | null) => any) | RefObject<Component<{ ...; }, any, any>> | undefined'.
  Type 'RefObject<StyledComponentClass<{}, {}, {}>>' is not assignable to type 'RefObject<Component<{ as?: string | ComponentClass<any, any> | StatelessComponent<any> | undefined; theme?: {} | undefined; }, any, any>>'.
    Type 'StyledComponentClass<{}, {}, {}>' is not assignable to type 'Component<{ as?: string | ComponentClass<any, any> | StatelessComponent<any> | undefined; theme?: {} | undefined; }, any, any>'.
      Property 'setState' is missing in type 'StyledComponentClass<{}, {}, {}>'.

如何在 TypeScript 语言中描述（定义）一个 ref？

也许这会有所帮助。

type MamkinHackerType<T> = T extends StyledComponentClass<React.DetailedHTMLProps<React.HTMLAttributes<infer ElementType>, infer ElementType>, infer T, infer H>
  ? ElementType & React.Component<React.DetailedHTMLProps<React.HTMLAttributes<ElementType>, ElementType> & T & H>
  : never
;

private readonly modalRef = React.createRef<MamkinHackerType<typeof ModalShadowContainer>>();
