首先，在pubspec.yaml中添加必要的依赖项：

dependencies: arcore_flutter_plugin: ^0.1.3
googleapis_auth: ^0.2.6 googleapis_storage: ^2.0.0

接下来，在Flutter应用程序中实例化ArCoreController并将其传递给ArCoreView，如下所示：

import 'package:arcore_flutter_plugin/arcore_flutter_plugin.dart';

class MyHomePage extends StatefulWidget { MyHomePage({Key key}) : super(key: key); @override _MyHomePageState createState() => _MyHomePageState(); }

class _MyHomePageState extends State { ArCoreController arCoreController;

@override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text("ARCore Demo"), ), body: ArCoreView( onArCoreViewCreated: _onArCoreViewCreated, enableTapRecognizer: true, ), ); }

void _onArCoreViewCreated(ArCoreController controller) { arCoreController = controller;

_add3DModel();

}

_add3DModel() async { final bytes = await rootBundle.load('assets/models/chair.glb'); arCoreController.addArCoreNodeWithAnchor( ArCoreReferenceNode( name: 'chair', objectUrl: '', scale: vector.Vector3(1.0, 1.0, 1.0), rotation: vector.Vector4(0.0, 1.0, 0.0, 0.0), position: vector.Vector3(0.0, 0.0, -1.0), ), arCoreController.createAnchor( Pose( translation: vector.Vector3( 0, 0, -1.0, ), rotation: vector.Vector4( 0, 0, 0, 0, ), ), ), ); }

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

这会在3D空间中添加一个椅子模型，该模型从应用的资源/assets/models/chair.glb中加载。要加载从互联网中获取的3D模型，使用objectUrl代替对象字节。
