final  DeepArController _controller = DeepArController();
_controller.initialize(
	androidLicenseKey:"---android key---",
	iosLicenseKey:"---iOS key---",
	resolution: Resolution.high);

2. Place the DeepArPreview widget in your widget tree to display the preview.

@override

Widget  build(BuildContext  context) {
return  _controller.isInitialized
		? DeepArPreview(_controller)
		: const  Center(
			child: Text("Loading Preview")
		);
}

3. Load effect of your choice by passing the asset file to it in switchPreview

_controller.switchEffect(effect);

4. To take a picture, use takeScreenshot() which return the picture as file.

final File file = await _controller.takeScreenshot();

if (_controller.isRecording) {
_controller.stopVideoRecording();
} else {
final File videoFile = _controller.startVideoRecording();
}
