To track the location in react native we have ‘geolocation’. Geolocation support both ios and android. Before using the geolocation we need to request to access the user location by adding below line in android/app/src/main/AndroidManifest.xml.

React Native is very similar to React, but one of the major difference is styling the components. For styling we use similar to CSS, is called Flexbox Layout. Mainly Flexbox purpose is to provide fixed layout on different screen sizes.
