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:

• Clone the repository.

  git clone https://github.com/sbis04/flutter_maps.git

• Open the project using your favorite IDE. For opening with VS Code:

  code flutter_maps

• For the Android part, go to android/app/src/main/AndroidManifest.xml file and add your API key here.

  <!-- Add your Google Maps API Key here --> <meta-data android:name="com.google.android.geo.API_KEY" android:value="AIzaSyBUz65tAUz21QOGgtK1IGsl-dkcKIitNPU"/>

• 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:

  <!-- Add your Google Maps API Key here --> <meta-data android:name="com.google.android.geo.API_KEY" android:value="AIzaSyBUz65tAUz21QOGgtK1IGsl-dkcKIitNPU"/>

• Also, you will need location access in the app. So, add the following permission in the same file inside the manifest tag:

  uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

iOS setup

• Navigate to the file ios/Runner/AppDelegate.swift and replace the whole code with the following:

  import UIKit import Flutter import GoogleMaps @UIApplicationMain @objc class AppDelegate: FlutterAppDelegate { override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { //Add your Google Maps API Key here GMSServices.provideAPIKey("AIzaSyBUz65tAUz21QOGgtK1IGsl-dkcKIitNPU") GeneratedPluginRegistrant.register(with: self) return super.application(application, didFinishLaunchingWithOptions: launchOptions) } }

• Also, add the following to ios/Runner/Info.plist file:
