当对话框打开时，Material ui v5 Appbar主题会更改

import React, { useState } from 'react';
import { AppBar, Toolbar, Typography, ThemeProvider, createTheme } from '@mui/material';

const DialogExample = () => {
  const [open, setOpen] = useState(false);

  const handleOpenDialog = () => {
    setOpen(true);
  };

  const handleCloseDialog = () => {
    setOpen(false);
  };

  const theme = createTheme({
    components: {
      MuiAppBar: {
        styleOverrides: {
          root: {
            backgroundColor: open ? 'red' : 'blue', // 根据对话框状态设置背景颜色
          },
        },
      },
    },
  });

  return (
    <ThemeProvider theme={theme}>
      <AppBar position="static">
        <Toolbar>
          <Typography variant="h6">My App</Typography>
        </Toolbar>
      </AppBar>
      {/* 在这里添加对话框组件 */}
    </ThemeProvider>
  );
};

export default DialogExample;
