  ./node_modules/react-native-ratings/src/SwipeRating.js
SyntaxError: /home/pmy/gitphone/node_modules/react-native-ratings/src/SwipeRating.js: Support for the experimental syntax 'classProperties' isn't currently enabled (41:23):39 | 
  40 | export default class SwipeRating extends Component {
> 41 |   static defaultProps = {
     |                       ^
  42 |     type: 'star',

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.

Expected behaviour
web version of create-react-native-web-app not to break...
