================================================
# Changelog
##0.7.3
* Update the examples with null-safety
## 0.7.2
* Fixes missing texturing on iOS
## 0.7.1
* Adds config to fix iOS cloud anchors not being able to upload
## 0.7.0
* Adds support to calculate distance between device and anchor and distance between two anchors
## 0.6.5
* Fixes the 'addNode' function to return true when a node is added to an anchor.
## 0.6.4
* Flutter 3 compatibility
## 0.6.3
* The function 'addNode' returned only true. You have now modified it to return false as well.
* Prevent apps from turning off when errors other than those on your camera occur.
## 0.6.2
* Slight changes in ```AndroidARView``` dispose methods to prevent memory overflow issues when AR view is closed and reopened multiple times
## 0.6.1
* Adds ```dispose``` method to ```ARSessionManager``` to prevent memory overflow issues when AR view is closed and reopened multiple times
## 0.6.0
* Adds handling of two gestures: panning and rotating
* Adds example showcasing handling and panning of nodes
* Adds animated coaching overlay for finding planes (uses standard animation from SceneKit/Sceneform on iOS/Android respectively) - active by default, can be turned off using ```ARSessionManager```
* Updates ```ARCore/CloudAnchors``` to 1.26.0 on iOS
* Removes overly restrictive permission for background location access on Android
## 0.5.1
* Removes overly restrictive background location permission on Android
## 0.5.0
* Adds new nodetypes ```fileSystemAppFolderGLB``` and ```fileSystemAppFolderGLTF2``` to load renderables from the device's local storage assigned to the current app
* Extends the ```localandwebobjectsexample``` of the example app to showcase the new form of model loading
* Adds snapshot functionality to the session manager to take screenshots of the ARView
* Adds ```screenshotexample``` to the example app to showcase the snapshot functionality
* Updates package versions of Flutter packages ```geolocator```, ```permission_handler```, ```vector_math```, and iOS package ```ARCore/CloudAnchors``` in the plugin
* Updates package versions of Flutter packages ```firebase_core```, ```cloud_firestore```, ```geoflutterfire```, and ```FirebaseSDKVersion ``` on iOS in the example application
## 0.4.3
* Updates documentation after publishing to [pub.dev](https://pub.dev)
## 0.4.2
* Updates documentation
* Deletes unnecessary files
## 0.4.1
* Adds External Model Management Example: A firebase database is used to store a list of 3D models (name, preview image, URI of the file location in a github repo). These models can be scrolled through and selected from in the example and can then be placed into the scene, uploaded through the Google Cloud Anchor API and downloaded on any other device with the app installed. The downloading user does not need to have the model "pre-installed", it is downloaded on the first occasion.
## 0.4.0
* Adds location manager which can be used to query the device's location (including permission and update handling)
* Adds geoflutterfire to support uploading GPS coordinates alongside anchors and downloading anchors and objects by their location
* Modifies cloud anchor example: Download button now queries and downloads all anchors along with the corresponding objects within a 100m radius of the device's current location
* Bugfix: fixes bug on Android causing some examples to crash because the cloud anchor manager wasn't initialized
## 0.3.0
* BREAKING CHANGE: Converts plugin to adhere to Flutter null safety
* Adds Cloud Anchor functionality (uploading and downloading anchors to/from the Google Cloud Anchor API), including keyless authentication
* Adds Cloud Anchor example demonstrating how to use Firebase to manage cloud anchor IDs and corresponding data (e.g. on-tap texts)
* Adds ```data``` member variable to ```ARNode``` as a flexible variable to hold any information associated with the node
## 0.2.1
* Bugfix: Handles singularities in affine transformation matrix deserialization on Android
## 0.2.0
* Adds AR Anchor as a common representation of anchors on all platforms
* Implements AR Plane Anchor as subclass of AR Anchor: Plane Anchors can be created in Flutter, registered on the target platform and then be used to attach nodes to
* Adds AR Hittest Result as a common representation of hittest results on all platforms. If the setting is activated in the session manager, taps on the platforms are registered and hit test results can be used to trigger callbacks in Flutter (example: hit result world coordinate transforms can be used to place anchors or nodes into the scene)
* Adds option to trigger callbacks when nodes are tapped
* Adds example to showcase hittests, creating and placing anchors and attaching nodes to anchors
## 0.1.0
* Adds AR Node as a common representation of nodes on all platforms
* Custom objects (GLTF2 models from Flutter's asset folders or GLB models from the Internet) can be attached to nodes and are loaded / downloaded asynchronously during runtime to ensure maximum flexibility
* AR Nodes (with attached objects) can be placed in the scene with respect to the world coordinate system, position, rotation and scale can be set and updated during runtime
* Updates debug option functionality: options can be changed at runtime (see Debug Option example)
* Updates examples to showcase current state of the plugin
## 0.0.1
* Coarse Plugin Architecture layed out
* ARView supports iOS (ARKit) and Android (ARCore) devices
* Camera Permission checks added
* Debug options added on both platforms: Feature Points visualization, detected planes visualization and world origin visualization
* Adds possibility to use own texture for plane visualization on both platforms

# ar_flutter_plugin
[](https://pub.dev/packages/ar_flutter_plugin)
Flutter Plugin for (collaborative) Augmented Reality - Supports ARKit for iOS and ARCore for Android devices.
Many thanks to Oleksandr Leuschenko for the [arkit_flutter_plugin](https://github.com/olexale/arkit_flutter_plugin) and to Gian Marco Di Francesco for the [arcore_flutter_plugin](https://github.com/giandifra/arcore_flutter_plugin) which both served as a great basis and starting point for this project.
## Getting Started
### Installing
Add the Flutter package to your project by running:
```bash
flutter pub add ar_flutter_plugin
```
Or manually add this to your `pubspec.yaml` file (and run `flutter pub get`):
# ar_flutter_plugin package extension
```yaml
dependencies:
ar_flutter_plugin: ^0.7.3
```
### Importing
Add this to your code:
```dart
import 'package:ar_flutter_plugin/ar_flutter_plugin.dart';
```
If you have problems with permissions on iOS (e.g. with the camera view not showing up even though camera access is allowed), add this to the ```podfile``` of your app's ```ios``` directory:
```pod
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
# Additional configuration options could already be set here
# BEGINNING OF WHAT YOU SHOULD ADD
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
'$(inherited)',
## dart: PermissionGroup.camera
'PERMISSION_CAMERA=1',
## dart: PermissionGroup.photos
'PERMISSION_PHOTOS=1',
## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
'PERMISSION_LOCATION=1',
## dart: PermissionGroup.sensors
'PERMISSION_SENSORS=1',
## dart: PermissionGroup.bluetooth
'PERMISSION_BLUETOOTH=1',
# add additional permission groups if required
]
# END OF WHAT YOU SHOULD ADD
end
end
end
```
### Example Applications
To try out the plugin, it is best to have a look at one of the following examples implemented in the `Example` app:
| Example Name | Description | Link to Code |
| ------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Debug Options | Simple AR scene with toggles to visualize the world origin, feature points and tracked planes | [Debug Options Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/debugoptionsexample.dart) |
| Local & Online Objects | AR scene with buttons to place GLTF objects from the flutter asset folders, GLB objects from the internet, or a GLB object from the app's Documents directory at a given position, rotation and scale. Additional buttons allow to modify scale, position and orientation with regard to the world origin after objects have been placed. | [Local & Online Objects Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/localandwebobjectsexample.dart) |
| Objects & Anchors on Planes | AR Scene in which tapping on a plane creates an anchor with a 3D model attached to it | [Objects & Anchors on Planes Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/objectgesturesexample.dart) |
| Object Transformation Gestures | Same as Objects & Anchors on Planes example, but objects can be panned and rotated using gestures after being placed | [Objects & Anchors on Planes Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/objectsonplanesexample.dart) |
| |
| Screenshots | Same as Objects & Anchors on Planes Example, but the snapshot function is used to take screenshots of the AR Scene | [Screenshots Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/screenshotexample.dart) |
| Cloud Anchors | AR Scene in which objects can be placed, uploaded and downloaded, thus creating an interactive AR experience that can be shared between multiple devices. Currently, the example allows to upload the last placed object along with its anchor and download all anchors within a radius of 100m along with all the attached objects (independent of which device originally placed the objects). As sharing the objects is done by using the Google Cloud Anchor Service and Firebase, this requires some additional setup, please read [Getting Started with cloud anchors](cloudAnchorSetup.md) | [Cloud Anchors Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/cloudanchorexample.dart) |
| External Object Management | Similar to the Cloud Anchors example, but contains UI to choose between different models. Rather than being hard-coded, an external database (Firestore) is used to manage the available models. As sharing the objects is done by using the Google Cloud Anchor Service and Firebase, this requires some additional setup, please read [Getting Started with cloud anchors](cloudAnchorSetup.md). Also make sure that in your Firestore database, the collection "models" contains some entries with the fields "name", "image", and "uri", where "uri" points to the raw file of a model in GLB format | [External Model Management Code](https://github.com/CariusLars/ar_flutter_plugin/blob/main/example/lib/examples/externalmodelmanagementexample.dart) |

# Getting Started with Cloud Anchors
The usual method of authentication is setting an API key. However, this authentication method only allows to host anchors with a maximum lifetime of 24 hours. OAuth 2.0 authentication allows saving uploaded anchors for up to 365 days and needs to be set up to use the plugin.
Follow the steps below to set up your application.
## Set up Google Cloud Anchor Service
The Google Cloud Anchor API is used by the plugin to upload, store and download AR anchors. If your app uses the plugin's shared AR experience features, the following setup steps are required:
1. Activate the [Cloud Anchor API](https://console.cloud.google.com/apis/api/arcorecloudanchor.googleapis.com) in your [Google Cloud Console](https://console.cloud.google.com) for the respective project
2. Register the Android part of your Flutter Application
* Perform the following steps to create a OAuth2 project (based on the [Android Cloud Anchors Developer Guide](https://developers.google.com/ar/develop/java/cloud-anchors/developer-guide-android?hl=en) and the [Guide for setting up OAuth 2.0](https://support.google.com/cloud/answer/6158849#zippy=)):
* Go to the [Google Cloud Platform Console](https://console.cloud.google.com).
* If the APIs & services page isn't already open, open the console left side menu and select APIs & services.
* On the left, click Credentials.
* Click New Credentials, then select OAuth client ID.
* Select "Android" as the Application type
* Fill in an arbitrary name and make sure the field "Package name" matches the package name in the ```AndroidManifest.xml``` of the Android part of your Flutter application
* Fill in the SHA-1 certificate fingerprint. If you're still in development, you can get the debug keystore key for the Android app by executing ```keytool -keystore ~/.android/debug.keystore -list -v``` in your terminal
* Click Create client ID
* If this is your first time creating a client ID, you have to configure your consent screen by clicking Consent Screen. The following procedure explains how to set up the Consent screen. You won't be prompted to configure the consent screen after you do it the first time.
* Go to the Google API Console [OAuth consent screen](https://console.cloud.google.com/apis/credentials/consent) page.
* Add required information like a product name and support email address.
* Click Add Scope.
* On the dialog that appears, select the ```ARCore Cloud Anchor API```scopes and any additional ones your project uses. Sensitive scopes display a lock icon next to the API name. (To select scopes for registration, you need to enable the API, like Drive or Gmail, from APIs & Services > API Library. You must select all scopes used by the project.)
* Finish the remaining steps of the OAuth consent screen setup.
* Enable keyless authentication in the Android part of your Flutter app (if you use the sample app of this plugin as a starting point, these steps are already done; the following steps are based on the [Android Cloud Anchors Developer Guide](https://developers.google.com/ar/develop/java/cloud-anchors/developer-guide-android?hl=en)):
* Add the dependency ```implementation 'com.google.android.gms:play-services-auth:16+'``` to the ```build.gradle``` file
* If you are using [ProGuard](https://www.guardsquare.com/en/products/proguard), add it to your app’s build.gradle file with
```java
buildTypes {
release {
...
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
```
* And add the following to your app’s proguard-rules.pro file:
```java
-keep class com.google.android.gms.common.** { *; }
-keep class com.google.android.gms.auth.** { *; }
-keep class com.google.android.gms.tasks.** { *; }
```
3. Register the iOS part of your Flutter Application
* Perform the following steps to create a Google Service account and signing key (based on the [iOS Cloud Anchor Developer Guide](https://developers.google.com/ar/develop/ios/cloud-anchors/developer-guide?hl=en)):
* In the navigation menu of the Google Cloud Platform console, go to APIs & Services > Credentials.
* Select the desired project, then click Create Credentials > Service account.
* Under Service account details, type a name for the new account, then click Create.
* On the Service account permissions page, go to the Select a role dropdown. Select Service Accounts > Service Account Token Creator, then click Continue.
* On the Grant users access to this service account page, click Done. This takes you back to APIs & Services > Credentials.
* On the Credentials page, scroll down to the Service Accounts section and click the name of the account you just created.
* On the Service account details page, scroll down to the Keys section and select Add Key > Create new key.
* Select JSON as the key type and click Create. This downloads a JSON file containing the private key to your machine.
* Add the contents of the JSON file you just downloaded to the iOS part of your Flutter application:
* Rename the file to ```cloudAnchorKey.json```
* Move or copy ```cloudAnchorKey.json``` into the example/ios/Runner directory.
* Open Xcode, then right-click on Runner directory and select Add Files to "Runner".
* Select ```cloudAnchorKey.json``` from the file manager.
* A dialog will show up and ask you to select the targets, select the Runner target.
## Set up Firebase
Google's Firebase cloud platform is used by the plugin's sample app to distribute and manage shared anchors and related content. If you want to use the included examples with shared AR experience features (e.g. the ```Cloud Anchors```example), the following setup steps are required (in your own apps, you can implement any method you like to distribute and manage the cloud anchor IDs that the plugin returns after uploading an anchor):
1. Create a new project in the [Firebase console](https://console.firebase.google.com/project/_/overview)
2. Register the Android part of your Flutter Application (based on the [FlutterFire Android Installation Guide](https://firebase.flutter.dev/docs/installation/android/)):
* Add a new Android app to your project and make sure the ```Android package name``` matches your local project's package name which can be found within the ```AndroidManifest.xml```
* Fill in the debug signing certificate SHA-1 field. If you're still in development, you can get the debug keystore key for the Android app by executing ```keytool -keystore ~/.android/debug.keystore -list -v``` in your terminal
* Once your Android app has been registered, download the configuration file from the Firebase Console (the file is called ```google-services.json```). Add this file into the ```android/app``` directory within your Flutter project
* Add the dependency ```classpath 'com.google.gms:google-services:4.3.3'``` to the top-level ```build.gradle```file of the Android part of your Flutter application
* Add ```apply plugin: 'com.google.gms.google-services'``` to the app-level ```build.gradle```file of the Android part of your Flutter application
3. Register the iOS part of your Flutter Application (based on the [FlutterFire iOS Installation Guide](https://firebase.flutter.dev/docs/installation/ios/)):
* Add a new iOS app to your project and make sure the ```iOS bundle ID``` matches your local project bundle ID which can be found within the "General" tab when opening ```ios/Runner.xcworkspace``` with Xcode.
* Download the file ```GoogleService-Info.plist```
* Move or copy ``` GoogleService-Info.plist``` into the example/ios/Runner directory.
* Open Xcode, then right-click on Runner directory and select Add Files to "Runner".
* Select ``` GoogleService-Info.plist``` from the file manager.
* A dialog will show up and ask you to select the targets, select the Runner target.
4. Enable Cloud Firestore for the project you created in step 1 (head to https://console.firebase.google.com/project/INSERT_YOUR_FIREBASE_PROJECT_NAME_HERE/firestore)
## Set up Location Services
* On the iOS part of your app, add the following to your Info.plist file (located under ios/Runner) in order to access the device's location:
```
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>
```

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
