How to get a versionName in react-native app on Android?

I've successfully used the React Native Device Info component to get the build details as specified in the Gradle config.

Once installed you can use:

DeviceInfo.getVersion()

To output the version, and:

DeviceInfo.getBuildNumber()

To get the build number.

If you want the version number in your package.json, you can also do:

var pkg = require('./package.json');
console.log(pkg.version);
