Note: ARKit is only supported by mobile devices with A9 or later processors (iPhone 6s/7/SE/8/X, iPad 2017/Pro) on iOS 11 and newer. For some features iOS 12 or newer is required.

Follow the installation instructions from Dart Packages site.

ARKit uses the device camera, so do not forget to provide the NSCameraUsageDescription. You may specify it in Info.plist like that:

    <key>NSCameraUsageDescription</key>
    <string>Describe why your app needs AR here.</string>

Prior to Flutter 1.22, platform views were in developers preview, hence if you want to use the plugin with old Flutter versions you need to add the following code to Info.plist:

    <key>io.flutter.embedded_views_preview</key>
    <string>YES</string>

The simplest code example:

import 'package:flutter/material.dart';
import 'package:arkit_plugin/arkit_plugin.dart';
import 'package:vector_math/vector_math_64.dart';

void main() => runApp(MaterialApp(home: MyApp()));

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  ARKitController arkitController;

  @override
  void dispose() {
    arkitController?.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) => Scaffold(
      appBar: AppBar(title: const Text('ARKit in Flutter')),
      body: ARKitSceneView(onARKitViewCreated: onARKitViewCreated));

  void onARKitViewCreated(ARKitController arkitController) {
    this.arkitController = arkitController;
    final node = ARKitNode(
        geometry: ARKitSphere(radius: 0.1), position: Vector3(0, 0, -0.5));
    this.arkitController.add(node);
  }
}

Result:

I would highly recommend to review the sample from the Example folder. You may find a couple of samples in the Example folder of the plugin. Some samples rely on this Earth image

If you prefer video here is a playlist with "AR in Flutter" videos:

You might want to check the device capabilities before establishing an AR session. Review the Check Support sample for the implementation details.

The plugin supports TrueDepth API. In case you didn't use it, your app will be rejected by Apple. Hence you need to remove any TrueDepth functionality by modifying your Podfile file

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

      config.build_settings['OTHER_SWIFT_FLAGS'] = '-DDISABLE_TRUEDEPTH_API'
    end
  end
end

• Is it possible to use this plugin on Android?
  No, as ARKit is not available on Android. You might want to try ARCore plugin instead.
• My app crashes when I open the AR scene several times. Why?
  Most probably that's because you didn't call dispose method on the ARKit controller.
• One of the features I need is merged in the repository, but is not available on pub.dev. How can I use the latest version?
  You may use the latest version by changing the pubspec.yaml dependency to:

dependencies:
  arkit_plugin:
    git: git://github.com/olexale/arkit_flutter_plugin.git
