arcore flutter plugin

I'm working to a new sceneview_flutter plugin to implement all features available in sceneview.
SceneView is a Sceneform Maintained replacement in Kotlin.
arcore_flutter_plugin #

Thanks to Oleksandr Leuschenko for inspiration and his precious code: arkit_flutter_plugin
Usage #
I wrote 2 articles for setup you project and start with ARCore Flutter Plugin:
ARCore Flutter Plugin: configurations.
ARCore Flutter Plugin: add object on the plane.
Configure your app #
To use this plugin, add arcore_flutter_plugin as a dependency in your pubspec.yaml file.

Follow official guide to enable ArCore

Add the Sceneform library to your app's build.gradle file:

android {
// Sceneform libraries use language constructs from Java 8.
// Add these compile options if targeting minSdkVersion < 26.
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
}

dependencies {
…

// Provides ArFragment, and other UX resources.
implementation 'com.google.ar.sceneform.ux:sceneform-ux:1.8.0'

// Alternatively, use ArSceneView without the UX dependency.
implementation 'com.google.ar.sceneform:core:1.8.0'
}

Import the Sceneform plugin into your project (OPTIONAL)

Example #
The simplest code example:
import 'package:arcore_flutter_plugin/arcore_flutter_plugin.dart';
import 'package:flutter/material.dart';
import 'package:vector_math/vector_math_64.dart' as vector;

class HelloWorld extends StatefulWidget {
@override
_HelloWorldState createState() => _HelloWorldState();
}

class _HelloWorldState extends State<HelloWorld> {
ArCoreController arCoreController;

@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Hello World'),
),
body: ArCoreView(
onArCoreViewCreated: _onArCoreViewCreated,
),
),
);
}

void _onArCoreViewCreated(ArCoreController controller) {
arCoreController = controller;

_addSphere(arCoreController);
_addCylindre(arCoreController);
_addCube(arCoreController);
}

void _addSphere(ArCoreController controller) {
final material = ArCoreMaterial(
color: Color.fromARGB(120, 66, 134, 244));
final sphere = ArCoreSphere(
materials: [material],
radius: 0.1,
);
final node = ArCoreNode(
shape: sphere,
position: vector.Vector3(0, 0, -1.5),
);
controller.addArCoreNode(node);
}

void _addCylindre(ArCoreController controller) {
final material = ArCoreMaterial(
color: Colors.red,
reflectance: 1.0,
);
final cylindre = ArCoreCylinder(
materials: [material],
radius: 0.5,
height: 0.3,
);
final node = ArCoreNode(
shape: cylindre,
position: vector.Vector3(0.0, -0.5, -2.0),
);
controller.addArCoreNode(node);
}

void _addCube(ArCoreController controller) {
final material = ArCoreMaterial(
color: Color.fromARGB(120, 66, 134, 244),
metallic: 1.0,
);
final cube = ArCoreCube(
materials: [material],
size: vector.Vector3(0.5, 0.5, 0.5),
);
final node = ArCoreNode(
shape: cube,
position: vector.Vector3(-0.5, 0.5, -3.5),
);
controller.addArCoreNode(node);
}

@override
void dispose() {
arCoreController.dispose();
super.dispose();
}
}

ArCoreView #
This class returns the view type. There are two types of views in it.
AUGMENTEDFACE
STANDARDVIEW
There are 4 properties in it:

onArCoreViewCreated
enableTapRecoginzer
enableUpdateListener
type

onArCoreViewCreated #
This property takes a ArCoreController.

enableTapRecoginzer
Initially, set to false. It is used as an argument by the MethodChannel.

enableUpdateListener
Initially, set to false. It is used as an argument by the MethodChannel.

type
It is a view type, it is either AUGMENTEDFACE, STANDARDVIEW*. It is set to STANDARDVIEW by default.

ArCoreController #
This controller used to add a ArNode using addArCoreNode function, add a ArCoreNode with ancher using a addArCoreNodeWithAncher function and also remove node using removeNode function.

ArCoreFaceView #
It is a stateful widget that returns a ArCoreAndroidView. It has two properties enableAugmentedFaces, onArCoreViewCreated.
Initially, enableAugmentedFaces is set to false.
onArCoreViewCreated takes a function with ArCoreController argument.

ArCoreFaceController #
It used dispose and loadMesh method to control the FaceView.

ArCoreSphere #
It is ArCoreShape, takes a radius & ArCoreMaterial.

ArCoreCylender #
It is ArCoreShape, takes a radius, height, & ArCoreMaterial.

ArCoreCube #
It is ArCoreShape, takes a size i.e. Vector3 & ArCoreMaterial.

ArCoreNode #
This widget is used to provide the position, shape, scale, rotation, name.

ArCoreMaterial #
It is used to describe the outlook of the virtual object created by the user.
It has color,textureBytes, metallic, roughness, reflection.

ArCoreRotatingNode #
It is an ArCoreNode with a degreesPerSecond property which is a double value.

ArCorePlane #
It takes the x, y coordinate of the plane, ArCorePose & ArCorePlaneType.
There are three types of plane:

HORIZONTAL_UPWARD_FACING
HORIZONTAL_DOWNWARD_FACING
VERTICAL

ArCoreReferenceNode #
It is ArCoreNode, it has all the properties that the ArCoreNode has also it has objectUrl and object3DFileName.

objectUrl #
URL of glft object for remote rendering.

object3DFileName #
Filename of sfb object in assets folder.
