Syntax 'classProperties' isn't currently enabled

If i use https://github.com/facebook/create-react-app to initiate and then use react-native-maps-directions i have the following error:

```
Support for the experimental syntax 'classProperties' isn't currently enabled (34:13):

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

```

I just installed `yarn add @babel/plugin-proposal-class-properties --dev` but i cant solve it 👎 . There is a way to run `react-native-maps-directions` using the `create-react-app` ?

Start by reproducing the Babel error in a project created with create-react-app while using react-native-maps-directions. Inspect the package and the application's Babel configuration to determine where the classProperties syntax is being parsed. Done means the package can be used in that setup without the reported syntax error, or the compatibility limitation is documented.
