why material-ui takes too much space?
<p>I am using webpack to bundle my react project. My project depends on material-ui for below component:</p>

<pre><code>material-ui/Dialog
material-ui/styles/getMuiTheme
material-ui/styles/MuiThemeProvider
material-ui/FlatButton
material-ui/TextField
</code></pre>

<p>webpack-bundle-size-analyzer reports material-ui takes 1.07MB size. Below is my webpack config file:</p>

<pre><code>const webpack = require('webpack');
const path = require('path');
const NpmInstallPlugin = require('npm-install-webpack-plugin');
const WebpackShellPlugin = require('webpack-shell-plugin');

const PATHS = {

<p>I already tried to use CompressionPlugin, UglifyJsPlugin to optimize my bundle files but it still takes more than 1MB. How can I reduce its size? I don't want to use gzip since my app is running on webview on mobile device and some of them doesn't support gzip encoding.</p>
