这是如何执行此操作的示例：

import React from "react";
import ReactDOM from "react-dom";

import {createMuiTheme, MuiThemeProvider, Button} from "@material-ui/core";

const theme = createMuiTheme({
  props: {
    MuiButton: {
      variant: "contained",
      color: "secondary"
    }
  }
});
function App() {
  return (
    <MuiThemeProvider theme={theme}>
      <Button>Props defaulted</Button>
    </MuiThemeProvider>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
