Building Location-Based Apps: Google Maps and Flutter

To create a Flutter app that allows users to choose cities and then displays a table with the population of each city using the google_maps_flutter package, you need to do a bit more setup. This includes integrating Google Maps into your app and obtaining an API key from Google Cloud Platform.

Here’s a step-by-step guide to building this app:

Step 1: Set Up Google Maps

1. Get a Google Maps API Key:

• Go to the Google Cloud Platform Console.
• Create a new project or select an existing one.
• Navigate to the APIs & Services dashboard and enable the Maps SDK for Flutter.
• Create credentials to get your API key.

2. Add Dependencies: In your pubspec.yaml file, add the google_maps_flutter package:

• dependencies: flutter: sdk: flutter google_maps_flutter: ^2.0.6

3. Run flutter pub get to install the new dependency.

4. Configure Your App:

• For Android, add your API key to the AndroidManifest.xml file:
• <application> <meta-data android:name="com.google.android.geo.API_KEY" android:value="YOUR_API_KEY"/> <!-- ... --> </application>
