How do you integrate Google Maps into a Flutter app?

Integrating Google Maps into a Flutter app is a valuable enhancement for applications requiring location-based services. To achieve this, Flutter developers can utilize the `google_maps_flutter` package, which simplifies the integration process. Here’s a step-by-step guide:

1. Add Dependency:

   Begin by adding the `google_maps_flutter` package to your `pubspec.yaml` file. Ensure the version is up-to-date.

```yaml
dependencies:
  google_maps_flutter: ^2.0.6
```

2. Obtain API Key:

   Acquire a Google Maps API key from the Google Cloud Console. This key is essential for authenticating your app’s access to the Google Maps services.

3. Android Configuration:

   In the `android/app/src/main/AndroidManifest.xml` file, insert the API key within the `<application>` element.

```xml
<application>
    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="YOUR_API_KEY_HERE" />
</application>
```

4. iOS Configuration:

   For iOS, in the `ios/Runner/AppDelegate.m` file, import the Google Maps package.

```dart
#import "AppDelegate.h"
#import "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GMSServices provideAPIKey:@"YOUR_API_KEY_HERE"];
  [GeneratedPluginRegistrant registerWithRegistry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

@end
```

5. Flutter Code:

   In your Flutter code, import the necessary packages:

```dart
import 'package:google_maps_flutter/google_maps_flutter.dart';
```

   Utilize the `GoogleMap` widget within your app, providing it with the API key and specifying initial parameters like `initialCameraPosition` and `markers` if needed.

```dart
GoogleMap(
  initialCameraPosition: CameraPosition(
    target: LatLng(latitude, longitude),
    zoom: 14.0,
  ),
)
```

   This basic setup enables you to display a Google Map within your Flutter app. Further customization and interactivity, such as adding markers or handling user gestures, can be implemented based on the specific requirements of your application.
