title: What is the appropriate webpack loader to use static keywords?
body: <p>I have the following error when I try to start my react-styleguidist documentation:</p>
  
  <pre><code>./node_modules/react-native-gesture-handler/touchables/TouchableHighlight.js 10:22
  Module parse failed: Unexpected token (10:22)
  You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

  | export default class TouchableHighlight extends Component {
  &gt;   static defaultProps = {
  |     ...GenericTouchable.defaultProps,
  |     activeOpacity: 0.85,
   @ ./node_modules/react-native-gesture-handler/touchables/index.js 6:0-69 6:0-69
   @ ./node_modules/react-native-gesture-handler/index.js
  </code></pre>
  
  <p>My <code>webpack.config.js</code> look like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>const createExpoWebpackConfigAsync = require('@expo/webpack-config');
  module.exports = async function (env, argv) {
    const config = await createExpoWebpackConfigAsync(env, argv);
    return config;
  };
  </code></pre>
  
  <p>My <code>babel.config.js</code> look like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>module.exports = function (api) {
    api.cache(true);
    return {
      presets: ['babel-preset-expo'],
      env: {
        development: {
          plugins: [
            '@babel/plugin-transform-react-jsx-source',
          ],
        },
      },
    };
  };
  </code></pre>
  
  <h2>Reproduction:</h2>
  
  <pre><code>git clone https://github.com/kopax/expo-bug-reports.git
  cd expo-bug-reports
  git checkout react-styleguidist
  npm i
  npm run styleguide
  </code></pre>
  
  <p>What is the appropriate Webpack loader to use the <code>static</code> keyword?</p>
