## Getting Started 🛠️

### Prerequisites
- Android Studio with Jetpack Compose support.
- Google Maps SDK for Android.
- **Google Maps API Key** 🔑: Obtain from [Google Cloud Console](https://console.cloud.google.com/) and add to your project.

> **Note**: Replace `YOUR_GOOGLE_API_KEY` in `AndroidManifest.xml` with your actual API key.

### Installation
1. Add the Google Maps SDK and Compose dependencies to your `build.gradle`:
   ```gradle
   implementation "com.google.maps.android:maps-compose:6.1.0"
   implementation "com.google.android.gms:play-services-maps:19.0.0"
   implementation "androidx.compose.material3:material3:1.3.0"
   ```
2. Add your API key to `AndroidManifest.xml`:
   ```xml
   <meta-data
       android:name="com.google.android.geo.API_KEY"
       android:value="YOUR_GOOGLE_API_KEY"/>
   ```
3. Sync your project and start using the composables.

## Usage Examples 📚

### 1. Basic Map
Display a map centered at Singapore with a marker:
```kotlin
@Composable
fun ComposeMapDemo() {
    val singapore = LatLng(1.3554117053046808, 103.86454252780209)
    val cameraPositionState = rememberCameraPositionState {
        position = CameraPosition.fromLatLngZoom(singapore, 10f)
    }
    GoogleMap(
        modifier = Modifier.fillMaxSize(),
        cameraPositionState = cameraPositionState
    ) {
        Marker(
            state = MarkerState(position = singapore),
            title = "Singapore",
            snippet = "Marker in Singapore"
        )
    }
}
```

### 2. Custom Marker with Info Window
Add a custom marker with a styled info window:
```kotlin
@Composable
fun ComposeMapCustomizingMarker() {
    val london = LatLng(51.52061810406676, -0.12635325270312533)
    val cameraPositionState = rememberCameraPositionState {
        position = CameraPosition.fromLatLngZoom(london, 10f)
    }
    GoogleMap(
        modifier = Modifier.fillMaxSize(),
        cameraPositionState = cameraPositionState
    ) {
        val icon = bitmapDescriptorFromVector(LocalContext.current, R.drawable.pin)
        MarkerInfoWindow(
            state = MarkerState(position = london),
            icon = icon
        ) {
            Box(
                modifier = Modifier.background(
                    color = MaterialTheme.colorScheme.onPrimary,
                    shape = RoundedCornerShape(35.dp)
                )
            ) {
                Column(
                    modifier = Modifier.padding(16.dp),
                    horizontalAlignment = Alignment.CenterHorizontally
                ) {
                    Image(painter = painterResource(id = R.drawable.map), ...)
                    Text(text = "Marker Title", ...)
                    Text(text = "Customizing a marker's info window", ...)
                }
            }
        }
    }
}
```

### 3. Draw Polyline
Draw a route between coordinates:
```kotlin
@Composable
fun ComposeMapMapPolyline() {
    val singapore = LatLng(44.811058, 20.4617586)
    val cameraPositionState = rememberCameraPositionState {
        position = CameraPosition.fromLatLngZoom(singapore, 11f)
    }
    GoogleMap(
        modifier = Modifier.fillMaxSize(),
        cameraPositionState = cameraPositionState
    ) {
        Polyline(
            points = listOf(
                LatLng(44.811058, 20.4617586),
                LatLng(44.811058, 20.4627586),
                ...
            ),
            color = Color.Magenta
        )
    }
}
```
