    "react-scripts": "3.0.1",
    "@material-ui/core": "^4.2.1",
    "@material-ui/icons": "^4.2.1",
    "@material-ui/styles": "^4.2.1",
    "styled-components": "^4.3.2"
  }

当我尝试以下内容theme时，props它是一个空对象。

StyledApp.js：

import styled from "styled-components";

export const StyledButtonUsingTheme = styled(Button)`

App.js：

import React from "react";

import { StylesProvider, ThemeProvider } from "@material-ui/styles";
import { createMuiTheme } from "@material-ui/core/styles";

import { StyledButtonUsingTheme } from "./StyledApp";
