如何从一个单独的文件中用Typescript覆盖材料UI主题？

import { createMuiTheme } from '@material-ui/core/styles';
import { ThemeOptions } from '@material-ui/core/styles/createMuiTheme';

const generateCustomTheme = (): ThemeOptions => {
  // 在这里定义你的自定义主题样式
  const customTheme = createMuiTheme({
    // 例如，更改主颜色为蓝色
    palette: {
      primary: {
        main: '#2196f3',
      },
    },
    // 添加其他自定义选项
    // ...
  });

  return customTheme;
};

export const customTheme = generateCustomTheme();

import { ThemeProvider } from '@material-ui/core/styles';

// ...

<ThemeProvider theme={customTheme}>
  {/* 在这里渲染你的组件 */}
</ThemeProvider>
