Flutter GPS Location

In this tutorial , we try to fetch phone GPS Location.

I used this library in pubspec.yaml file under dependencies

dependencies:
  location: ^2.3.5

Android #

In order to use this plugin in Android, you have to add this permission in AndroidManifest.xml :
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Permission check for Android 6+ was added.
iOS #
And to use it in iOS, you have to add this permission in Info.plist :
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
Warning: there is a currently a bug in iOS simulator in which you have to manually select a Location several in order for the Simulator to actually send data. Please keep that in mind when testing in iOS simulator.
