### Add ar_flutter_plugin to Project

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/index.html

Install the ar_flutter_plugin package using the Flutter CLI.

```bash
flutter pub add ar_flutter_plugin

```

--------------------------------

### startLocationUpdates Method

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_location_manager/ARLocationManager/startLocationUpdates.html

Starts high precision location updates to keep track of the device's position. It automatically queries user permission if possible and returns true if successful, or an error if permissions do not suffice.

```APIDOC
## startLocationUpdates()

### Description
Starts high precision location updates to keep track of the device's position. Returns true or an error, if permissions don't suffice. Automatically queries user permission if possible.

### Method Signature
Future<bool> startLocationUpdates()

### Returns
- `Future<bool>`: Resolves to `true` if location updates are successfully started, otherwise returns a `Future.error` with a message indicating the reason (e.g., 'Location services disabled', 'Location permissions denied', 'Location permissions permanently denied').

### Implementation Notes
This method first checks if location services are enabled. If not, it returns an error. It then checks for location permissions, requesting them if denied. If permissions are permanently denied, it returns an error. Upon successful permission grant, it sets up a stream for high accuracy location updates and returns `true`.
```

--------------------------------

### currentLocation

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_location_manager/ARLocationManager-class.html

Gets or sets the current position of the device.

```APIDOC
## currentLocation

### Description
Provides access to the current geographical position of the device. This is a getter/setter pair.

### Property
- **currentLocation** (Position) - Gets or sets the current position.
```

--------------------------------

### onPanStart Property

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_object_manager/ARObjectManager/onPanStart.html

The onPanStart property is a getter/setter pair that accepts a NodePanStartHandler. This handler is invoked when a pan gesture begins on an AR object, allowing for custom logic to be executed at the start of the gesture.

```APIDOC
## onPanStart Property

### Description

This property is a handler that is called when a pan gesture starts on an AR object. It allows you to define custom behavior for the beginning of a pan gesture.

### Type

`NodePanStartHandler?`

### Implementation

```dart
NodePanStartHandler? onPanStart;
```

### Usage

Assign a function or method that matches the `NodePanStartHandler` signature to this property to handle the pan start event.
```

--------------------------------

### Open App Settings

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_location_manager/ARLocationManager/openAppPermissionSettings.html

Call this method to open the current application's settings screen. This is useful for guiding users to grant necessary permissions.

```dart
void openAppPermissionSettings() async {
  await Geolocator.openAppSettings();
}
```

--------------------------------

### onRotationStart Property

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_object_manager/ARObjectManager/onRotationStart.html

This property allows you to set a handler for when the rotation of an AR object starts. It is a getter/setter pair.

```APIDOC
## onRotationStart Property

NodeRotationStartHandler? onRotationStart

getter/setter pair

### Description

This property allows you to register a callback function that will be executed when the rotation of an AR object begins. It acts as both a getter to retrieve the current handler and a setter to assign a new one.

### Type

`NodeRotationStartHandler?`

### Usage

```dart
// Set a handler
ARObjectManager.onRotationStart = (node) {
  print('Rotation started for node: ${node.name}');
};

// Get the current handler
var handler = ARObjectManager.onRotationStart;
```
```

}
```

--------------------------------

### Get Platform Version

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/ar_flutter_plugin/ArFlutterPlugin/platformVersion.html

This method invokes a platform channel to retrieve the version string from the native platform. Ensure the platform channel is set up correctly.

```dart
static Future<String> get platformVersion async {
  final String version = await _channel.invokeMethod('getPlatformVersion');
  return version;
}
```

--------------------------------

### Implement Snapshot Capture

Source: https://pub.dev/documentation/ar_flutter_plugin/latest/managers_ar_session_manager/ARSessionManager/snapshot.html

Use this method to get an ImageProvider of the current AR scene. It invokes a platform channel method to retrieve the scene data as Uint8List.

```dart
Future<ImageProvider> snapshot() async {
  final result = await _channel.invokeMethod<Uint8List>('snapshot');
  return MemoryImage(result!);
}
```

  // Test if location services are enabled.
  serviceEnabled = await Geolocator.isLocationServiceEnabled();
  if (!serviceEnabled) {
    // Location services are not enabled don't continue
    // accessing the position and request users of the
    // App to enable the location services.
    return Future.error('Location services disabled');
  }

  permission = await Geolocator.checkPermission();
  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.denied) {
      // Permissions are denied, next time you could try
      // requesting permissions again (this is also where
      // Android's shouldShowRequestPermissionRationale
      // returned true. According to Android guidelines
      // your App should show an explanatory UI now.
      return Future.error('Location permissions denied');
    }
  }

  if (permission == LocationPermission.deniedForever) {
    // Permissions are denied forever, handle appropriately.
    return Future.error('Location permissions permanently denied');
  }

  // When we reach here, permissions are granted and we can
  // continue accessing the position of the device.
  locationStream = 
      Geolocator.getPositionStream(locationSettings: LocationSettings(accuracy: LocationAccuracy.high))
          .listen((Position position) {

    return Future.error('Location services disabled');
  }

  permission = await Geolocator.checkPermission();
  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.denied) {
      // Permissions are denied, next time you could try
      // requesting permissions again (this is also where
