neom_ar

A highly optimized, cross-platform Augmented Reality (AR) library for Flutter. neom_ar encapsulates ARKit (iOS) and ARCore (Android) behind a unified, pure-Dart interface, providing real-time surface detection, distance measurement, and 3D room volume scanning.

It is designed to seamlessly integrate with neighboring acoustic levitation systems (such as neom_levitation) by scanning spatial physical bounds and automatically calculating room dimensions.

Features

• 📱 Cross-Platform AR Support: Automatically mounts ARKitSceneView on iOS and ArCoreView on Android.
• 📐 High-Precision Distance Measurement: Tap two points in real-world space to measure distances with millimetric accuracy.
• 🚪 Volumetric Room Scanner: Interactively measure and assign Width (X), Depth (Y), and Height (Z) dimensions to scan complete physical chambers.
• 🧪 Automatic Volume Calculation: Computes chamber volumes in cubic meters ($m^3$) on-the-fly.
• 📡 Levitation Bridge: Built-in deferred routing and state transmission to export measured bounds directly to acoustic simulation environments.
• 💻 Offline Stubs: Includes a robust mock stub fallback allowing developers to test features on desktop or non-AR hardware seamlessly.

Quick Start

1. Configure Platforms

Ensure your target platforms meet the following requirements:

• iOS: iOS 11.3+ and ARKit-compatible device. Add NSCameraUsageDescription to your Info.plist.
• Android: Android SDK 24+ and Google Play Services for AR installed.

2. Basic Usage

Use the high-level ArMeasurePage directly, or instantiate the ArMeasureController for custom interfaces:

import 'package:flutter/material.dart';
import 'package:neom_ar/lib/ui/pages/ar_measure_page.dart';
import 'package:sint/sint.dart';

void main() {
  runApp(
    MaterialApp(
      home: const ArMeasurePage(),
    ),
  );
}

API Architecture

The package exposes the following main domain boundaries:

• ArPose: Represents a 3D coordinate point $(x, y, z)$ with orientation quaternion quaternions.
• ArPlane: Holds dimensions, types, and areas of detected real-world surfaces.
• ArMeasurement: Wraps two points, computing physical distance and returning formatted strings (e.g. 24.5 cm or 1.85 m).
• ArService: General abstraction interface implementing platform-specific controllers for ARCore and ARKit.
