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 is required.

Follow the installation instructions from Dart Packages site.

The plugin use native view from ARKit, which is not yet supported by default. To make it work add the following code to Info.plist:

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

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>

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

You might want to check the device capabilities before establishing an AR session. To do that the device_info plugin will be in hand. Check the documentation about AR functionality you want to add and implement some fallback logic for users with older OSes.

If you find a bug or would like to request a new feature, just open an issue. Your contributions are always welcome!
