MaterialUI在点击事件后显示另一个视图

Question

我在MaterialUI中是全新的。我现在正在处理我的第一个项目，并试图利用其页面上的模板。我已经用登录视图和主仪表板视图加载了两个.tsx文件。在登录视图上单击“登录”按钮后，我想显示主仪表板视图。这两个文件都有自己的导出默认函数FnName（）函数和const classes = useStyles（）;函数，这似乎引起了我的问题。我猜这里是使用钩子的方式的问题。但是如何将该函数传递给onClick处理程序事件按钮？您可以在这里看到我的项目：

有人可以帮忙吗？

import SignIn from "./material-ui/signin-template/SignIn";
import {BrowserRouter as Router, Switch, Route} from "react-router-dom";
import { createBrowserHistory as history} from 'history';
import MiniDrawer from "./material-ui/signin-template/Dashboard";

class App extends React.Component {
    render() {
        return (
            <div>
                <Router history={history}>
                    <Switch>
