Use Geocoding for converting addresses to coordinates and vice versa
Add Markers to the Map View
Draw the route between two places using Polylines and Directions API
Calculate the actual distance of the route
Usage
Before using it, you will need to make a new project in the Google Cloud Platform, and enable the Google Maps API for that project. Also, don't forget to setup the Billing for that project on GCP, otherwise you will receive the following error:
For the iOS part, go to ios/Runner/AppDelegate.swift file and add your API key here.
GMSServices.provideAPIKey("YOUR KEY HERE")
Go to the lib/secrets.dart file and add your API key here.
Full configuration (already done in this project)
You do not require to complete these configurations if you are cloning this project, as they are already done in it. But these may be helpful if you are setting up a new Flutter project for using Google Maps and location services.
Android setup
Navigate to the file android/app/src/main/AndroidManifest.xml and add the following code snippet inside the application tag:
Navigate to the file ios/Runner/AppDelegate.swift and replace the whole code with the following:
importUIKitimportFlutterimportGoogleMaps@UIApplicationMain@objcclassAppDelegate: FlutterAppDelegate {
overridefuncapplication(
_application: UIApplication,
didFinishLaunchingWithOptionslaunchOptions: [UIApplication.LaunchOptionsKey: Any]?
) ->Bool {
//Add your Google Maps API Key here
GMSServices.provideAPIKey("YOUR KEY HERE")
GeneratedPluginRegistrant.register(with: self)
returnsuper.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
Also, add the following to ios/Runner/Info.plist file:
io.flutter.embedded_views_previewYES
For getting location permission, add the following to the same file:
NSLocationWhenInUseUsageDescriptionThis app needs access to location when open.
This completes the setup for both the platforms in Flutter.
