reactjs - 带有 Typescript 和 ThemeProvider 的 StyledComponents。什么是正确的类型？

Question

在将 StyledComponents 与 ThemeProvider 一起使用时，我无法获得正确的类型。
我已经用这种方法试过了:
https://github.com/styled-components/styled-components/issues/1589
到目前为止我的代码:
应用程序.tsx

import * as React from "react";
import "./styles.css";
import theme from "./theme";
import { ThemeProvider } from "styled-components";
import StyledButton from "./StyledButton";

export default function App() {
  return (
    <ThemeProvider theme={theme}>
      <div className="App">
        <StyledButton variant="primary">MyButton</StyledButton>
      </div>
    </ThemeProvider>
  );
}

主题.ts

import "styled-components";
const theme = {
  borderRadius: "0.7rem",
  color: "yellow"
};

export default theme;

StyledButton.tsx

import styled from "styled-components";

interface IButtonProps {
  color: string;
  backgroundColor: string;
  borderRadius?: string;
}

const buttonProps = (props: any): IButtonProps => {
  /* defaultValues / primary */
  let bp: IButtonProps = {
    color: props.theme.color,
    backgroundColor: "#2862c3c4"
  };

  if (props.variant === "primary") {
    return bp;
  } else if (props.variant === "secondary") {
    bp.color = "white";
    bp.backgroundColor = "#808080c2";
  }

  return bp;
};

const StyledButton = styled.button<IButtonProps>`
  color: ${props => (props.color ? props.color : buttonProps(props).color)};
  background-color: ${props =>
    props.backgroundColor
      ? props.backgroundColor
      : buttonProps(props).backgroundColor};
  border-radius: ${props => props.theme.borderRadius};
`;

export default StyledButton;

styled-components.d.ts

import theme from "./globals/theme";

type CustomTheme = typeof theme;

declare module "styled-components" {
  export interface DefaultTheme extends CustomTheme {}
}

那么我必须改变什么才能摆脱 任何 输入:

const buttonProps = (props: any): IButtonProps

以及变体的 ts 警告:

<StyledButton variant="primary">MyButton</StyledButton>

它在 official documentation 中有描述.
在 .d.ts文件添加这个:

import 'styled-components';

declare module 'styled-components' {
  export interface DefaultTheme {
     borderRadius: string;
     color: string;
  }
}
