5/ To handle camera and microphone permissions, please add the following strings to your info.plist.

<key>NSCameraUsageDescription</key>
<string>---Reason----</string>
<key>NSMicrophoneUsageDescription</key>
<string>---Reason----</string>

6/ Also add the following to your Podfile file:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    ... # Here are some configurations automatically generated by flutter

    # Start of the deepar configuration
    target.build_configurations.each do |config|

   config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        ## dart: PermissionGroup.camera
         'PERMISSION_CAMERA=1',

        ## dart: PermissionGroup.microphone
         'PERMISSION_MICROPHONE=1',    
      ]

    end 
    # End of the permission_handler configuration
  end
end 

Flutter Installation Steps

1/ Initialize DeepArController by passing in your license keys for both platforms.

<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 an 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();

5/ To record a video use the following:

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