-```
+From the command line:
+
+```bash
 flutter channel master
 flutter upgrade
 flutter config --enable-native-assets  
 ```
 
-```
+In your Flutter app:
-_thermionViewer = await ThermionFlutterPlugin.createViewer();
 
-// Geometry and models are represented as "entities". Here, we load a glTF
+```dart
-// file containing a plain cube.
+@override
-// By default, all paths are treated as asset paths. To load from a file 
-// instead, use file:// URIs.
-var entity =
-    await _thermionViewer!.loadGlb("assets/cube.glb", keepData: true);
-
-// Thermion uses a right-handed coordinate system where +Y is up and -Z is
-// "into" the screen.
-// By default, the camera is located at (0,0,0) looking at (0,0,-1); this
-// would place it directly inside the cube we just loaded.
-//
-// Let's move the camera to (0,0,10) to ensure the cube is visible in the
-// viewport.
-await _thermionViewer!.setCameraPosition(0, 0, 10);
-
-// Without a light source, your scene will be totally black. Let's load a skybox
-// (a cubemap image that is rendered behind everything else in the scene)
-// and an image-based indirect light that has been precomputed from the same
-// skybox.
-await _thermionViewer!.loadSkybox("assets/default_env_skybox.ktx");
-await _thermionViewer!.loadIbl("assets/default_env_ibl.ktx");
-
-// Finally, you need to explicitly enable rendering. Setting rendering to
-// false is designed to allow you to pause rendering to conserve battery life
-await _thermionViewer!.setRendering(true);
-```
-
-and then in your Flutter application:
-```
- @override
   Widget build(BuildContext context) {
-    return Stack(children: [
+    return Scaffold(
-      if (_thermionViewer != null)
+        body: Stack(children: [
         Positioned.fill(
-            child: ThermionWidget(
+            child: ViewerWidget(
-          viewer: _thermionViewer!,
+          assetPath: "assets/cube.glb",
-        )),
+          skyboxPath: "assets/default_env_skybox.ktx",
-    ]);
+          iblPath: "assets/default_env_ibl.ktx",
+          transformToUnitCube: true,
+          initialCameraPosition: Vector3(0, 0, 6),

+            await viewer.removeSkybox();
+          },
+          initial: Container(
+            color: Colors.red,
+          ),
+        ))]));
   }
 ```
 
+> the first time you build an app that consumes this package, the Dart native-assets build system will download static binaries from Cloudflare. This may take a few minutes (depending on which platform you are compiling for). These will be cached, so subsequent builds will be much faster.

+After changing the `hooks` section, make sure you run `flutter clean` to propagate the changes correctly.
+
+> [!CAUTION]
+> Debug builds won't work for Android. This is a known upstream issue with Filament.

+## iOS
+
+### Min iOS version
+
+Thermion requires a minimum iOS version of 13.0. When building a Flutter application, ensure your application's `ios/Podfile` contains the following:
+
+```ruby
+platform :ios, '13.0'
+```
+
+and in ios/Info.plist:
+
+```xml
+<key>LSMinimumSystemVersion</key>
+<string>13.0</string>
+```
+
+When submitting to the App Store, you may encounter an error saying `thermion_dart.framework does not supported the minimum deployment target in Info.plist`. 
+
+This is because Flutter hardcodes a deployment target of iOS 12.0 when invoking the native assets build, which conflicts with actual requirement.
+
+After running `flutter build ios` (but before archiving the build and submitting to the App Store), run the following script to replace the `MinimumOSVersion`:

+## Linux support
+
+Currently, only the Dart package (`thermion_dart`) will work on Linux (primarily for the automated build/testing pipeline). 
+
+Filament has been built for Ubuntu 22.04; other distributions may work, but YMMV.
+
+The Flutter package (`thermion_flutter`) won't work; it's missing the platform glue code necessary to set up the render target.  Support will eventually be added, but there is currently no estimated timeline.
+
+Contributions are welcome and it's actually not a lot of work. Join the Discord if you want to help out.

-## Quickstart (Flutter)
+# ViewerWidget Documentation
 
-> You can find the entire project below in the [flutter/quickstart](https://github.com/nmfisher/thermion_examples/tree/master/flutter/quickstart) folder of the `thermion_examples` repository.
+`ViewerWidget` is a simplified wrapper around the Thermion 3D viewer that makes it easy to display 3D models in your Flutter application.
 
-1. Switch to Flutter master channel, upgrade Flutter, create a new project, then add `thermion_flutter` as a dependency
+## Overview
 
-```bash
+`ViewerWidget` handles the setup and configuration of a Thermion viewer, including:
-$ flutter channel master
+- Loading 3D models (glTF assets)
-$ flutter upgrade
+- Configuring skyboxes and image-based lighting
-$ flutter config --enable-native-assets  
+- Setting up camera positions and manipulators
-$ flutter create thermion_sample_project && cd thermion_sample_project
+- Managing the rendering lifecycle
-$ flutter pub add thermion_flutter
-```
 
-2. If running on iOS or MacOS, change the minimum deployment target to OSX 13
+## Installation
 
-<Accordion title="Click to open iOS/MacOS instructions">
+First, make sure you have the Thermion Flutter plugin added to your dependencies:
-
-Make sure the `platform` entry refers to `13.0` in your Podfile.
-
-In `macos/Podfile` (for macOS):
-```
-platform :osx, '13.0'
-```
-
-In `ios/Podfile`, (for iOS):
-```
-platform :ios, '13.0'
-```
-
-Then open XCode:
-```
-open macos/Runner.xcworkspace
-```
-
-and change the minimum deployment target to 13.0:
-
-![XCode screenshot](images/macos_min_deployment.png)
-
-</Accordion>
-
-2. Add a folder containing your assets (glTF model + skybox ktx) to your `pubspec.yaml` asset list
 
 ```yaml
-...
+dependencies:
-flutter
+  thermion_flutter: ^latest_version
-  uses-material-design: true
-  assets:
-    - assets/
 ```
 
-3. Create an instance of `ThermionFlutterPlugin` in your app.
+## Basic Usage
 
 ```dart
+import 'package:flutter/material.dart';
+import 'package:thermion_flutter/thermion_flutter.dart';
+import 'path_to_your_viewer_widget.dart';
 
-class _MyAppState extends State<MyApp> {
+class MyApp extends StatelessWidget {
-  late ThermionFlutterPlugin _thermionFlutterPlugin;  
+  @override
-  late Future<ThermionViewer> _thermionViewer;
+  Widget build(BuildContext context) {
-  void initState() {    
+    return MaterialApp(
-    _thermionFlutterPlugin = ThermionFlutterPlugin();    
+      home: Scaffold(
-    _thermionViewer = _thermionFlutterPlugin.createViewer();  
+        body: ViewerWidget(
+          assetPath: 'assets/my_model.glb',
+          initialCameraPosition: Vector3(0, 0, 5),
+          manipulatorType: ManipulatorType.ORBIT,
+        ),
+      ),
+    );
   }
 }
-
 ```
 
+## Properties
 
-4. Add a `ThermionWidget` to your widget hierarchy 
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `initial` | `Widget` | Red decorated box | Widget to display while the viewer is loading |
+| `initialCameraPosition` | `Vector3` | `Vector3(0, 0, 5)` | The starting position for the camera (looking towards origin) |
+| `showFpsCounter` | `bool` | `false` | Whether to show an FPS counter overlay |
+| `assetPath` | `String?` | `null` | Path to the glTF asset to load |
+| `skyboxPath` | `String?` | `null` | Path to a KTX skybox image |
+| `iblPath` | `String?` | `null` | Path to a KTX image for image-based lighting |
+| `directLightType` | `LightType?` | `null` | Type of direct light to add to the scene |
+| `transformToUnitCube` | `bool` | `true` | If true, rescales the model to fit within a 1x1x1 cube |
+| `postProcessing` | `bool` | `true` | Enables ACES tone mapping and basic anti-aliasing |
+| `background` | `Color?` | `null` | Background color (not visible when skybox is provided) |
+| `destroyEngineOnUnload` | `bool` | `false` | If true, disposes the engine when widget is disposed |
+| `manipulatorType` | `ManipulatorType` | `ORBIT` | Type of camera control to use |
+| `onViewerAvailable` | `Future Function(ThermionViewer)?` | `null` | Callback when viewer is ready |
+
+## Camera Manipulators
+
+`ViewerWidget` supports three different camera manipulation modes:
+
+- `ManipulatorType.NONE`: No camera controls, static view
+- `ManipulatorType.ORBIT`: Orbit controls (pinch to zoom, swipe to rotate)
+- `ManipulatorType.FREE_FLIGHT`: Free flight controls for unrestricted movement
+
+Example:
 
 ```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  manipulatorType: ManipulatorType.FREE_FLIGHT,
+)
+```
 
-class _MyAppState extends State<MyApp> {
+## Lighting
+
+You can set up lighting in multiple ways:
+
+### Image-Based Lighting
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  iblPath: 'assets/environment.ktx',
+)
+```
+
+### Direct Light
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  directLightType: LightType.SUN,
+)
+```
+
+## Advanced Usage
+
+### Accessing the Viewer
+
+You can get access to the underlying `ThermionViewer` object for more advanced control:
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  onViewerAvailable: (viewer) async {
+    // Now you can use the viewer directly
+    final camera = await viewer.getActiveCamera();
+    await camera.lookAt(Vector3(0, 1, 5));
     
-    ThermionViewer? _thermionViewer;
+    // Add custom lights, manipulate materials, etc.
-    void initState() {    
+  },
-        _thermionFlutterPlugin.createViewer().then((viewer) {
+)
-            setState(() {
+```
-                _thermionViewer = viewer;
-            });
-        });
-    }    
 
-    Widget build(BuildContext context) {
+### Changing Manipulator at Runtime
-        return Stack(children:[
+
-            if(_thermionViewer != null)
+The `manipulatorType` is the only property that can be changed after the widget is created:
-            Positioned.fill(
+
-                child:ThermionWidget(
+```dart
-                    plugin:_thermionViewer!
+class _MyWidgetState extends State<MyWidget> {
-                ) 
+  ManipulatorType _manipulatorType = ManipulatorType.ORBIT;
-            )
+  
-        ]);  
+  @override
-    }
+  Widget build(BuildContext context) {
+    return Column(
+      children: [
+        Expanded(
+          child: ViewerWidget(
+            assetPath: 'assets/model.glb',
+            manipulatorType: _manipulatorType,
+          ),
+        ),
+        Row(
+          children: [
+            ElevatedButton(
+              onPressed: () {
+                setState(() {
+                  _manipulatorType = ManipulatorType.ORBIT;
+                });
+              },
+              child: Text('Orbit'),
+            ),
+            ElevatedButton(
+              onPressed: () {
+                setState(() {
+                  _manipulatorType = ManipulatorType.FREE_FLIGHT;
+                });
+              },
+              child: Text('Free Flight'),
+            ),
+          ],
+        ),
+      ],
+    );
+  }
 }
-
 ```
 
-4. Add a button to load the model when pressed
+## Limitations
+
+- Only the `manipulatorType` property can be changed at runtime. For any other property changes, create a new widget.
+- The widget requires that you have the correct environment setup for Thermion (Flutter master channel with native assets enabled).
+
+## Example
+
+Here's a complete example showing how to use `ViewerWidget` with multiple configuration options:
 
 ```dart
+import 'package:flutter/material.dart';
+import 'package:thermion_flutter/thermion_flutter.dart';
+import 'package:vector_math/vector_math_64.dart';
 
-...
+class ModelViewer extends StatelessWidget {
-
+  @override
-class _MyAppState extends State<MyApp> {
+  Widget build(BuildContext context) {
-    
+    return Scaffold(
-...
+      appBar: AppBar(title: Text('3D Model Viewer')),
-    
+      body: ViewerWidget(
-    bool _loaded = false;
+        assetPath: 'assets/robot.glb',
-
+        skyboxPath: 'assets/studio_skybox.ktx',
-    Widget build(BuildContext context) {
+        iblPath: 'assets/studio_ibl.ktx',
-        return Stack(children:[
+        initialCameraPosition: Vector3(0, 1.5, 3),
-            if(_thermionViewer != null)
+        manipulatorType: ManipulatorType.ORBIT,
-            Positioned.fill(
+        showFpsCounter: true,
-                child:ThermionWidget(
+        background: Colors.grey,
-                    plugin:_thermionViewer!
+        postProcessing: true,
-                ) 
+        transformToUnitCube: true,
-            ),
+        onViewerAvailable: (viewer) async {
-            if (!_loaded)
+          // You can perform additional setup here
-                Center(
+          print('Viewer is ready!');
-                    child: ElevatedButton(
+        },
-                        child: const Text("Load"),
+      ),
-                        onPressed: () async {
+    );
-                            // TODO 
+  }
-                            _loaded = true;
-                            setState(() {});
-                        }))
-        ]);  
-}}
-```
-
-5. When the button is pressed, load a skybox, lighting and the glb asset
-
-You will need to import the `dart:math` and `package:vector_math` libraries.
-
-```dart
-import 'package:vector_math/vector_math_64.dart' as v;
-import 'dart:math';
-
-...
-
-class _MyAppState extends State<MyApp> {
-
-    ...
-
-    Widget build(BuildContext context) {
-        return Stack(children:[
-            ...
-            if(!_loaded)
-                Center(
-                    child: ElevatedButton(
-                        child: const Text("Load"),
-                        onPressed: () async {
-                            var viewer = await _thermionViewer;
-                            await viewer.loadIbl("assets/default_env_ibl.ktx");
-                            await viewer.loadSkybox("assets/default_env_skybox.ktx");
-                            await viewer.loadGlb("assets/cube.glb");
-
-                            await viewer.setCameraPosition(0, 1, 10);
-                            await viewer.setCameraRotation(v.Quaternion.axisAngle(
-                                    v.Vector3(1, 0, 0), -30 / 180 * pi) *
-                                v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
-                            await viewer.addLight(
-                                LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
-                            await viewer.setRendering(true);
-                            _loaded = true;
-                            setState(() {});
-                        }
-                    )
-                )
-        ]);
-    }
 }
-```           
+```
-
-Here, we've added a skybox (the background (cube) image rendered behind all other elements in the scene), image-based lighting (where an image is used to determine the direction and intensity of a light source) and a directional light (Sun).
-
-Anything added to the scene is referred to as an "entity" (including lights and cameras).
-
-Entities are always added to the scene at position (0,0,0).
-
-The default scene camera is located at (0,0,0) (and is looking at -Z, or "into" the screen), so by adding a cube at (0,0,0), the camera will now be inside the cube. 
-
-We need to move the camera outside the cube so it's visible. 
-
-6. Change the camera orientation
-```dart
-   var viewer = await _thermionViewer;
-    await viewer.loadSkybox("assets/default_env_skybox.ktx");
-    await viewer.loadGlb("assets/cube.glb");
-
-    await viewer.setCameraPosition(0, 1, 10);
-    await viewer.setCameraRotation(v.Quaternion.axisAngle(
-                        v.Vector3(1, 0, 0), -30 / 180 * pi) *
-                    v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
-```
-
-The cube still won't be visible until we add a light to the scene and tell Thermion to start rendering.
-
-7. Add a light and turn rendering on
-```dart 
-    ...
-    await viewer.addLight(
-                    LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
-    await viewer.setRendering(true);
-    ...
-````
-
-8. Run the project
-```
-$ flutter run -d macos
-```
-
-> You may experience a noticeable delay the very first time you run the project. Don't panic, it's not frozen! This is due to the build system downloading the prebuilt Filament binaries from Cloudflare, which can take some time (particularly on Windows). These binaries will be cached after first download, so subsequent runs will be much faster (though every time you run flutter clean, the binaries will be re-downloaded).

+        ]);
+    }
+}
+```           
+
+Here, we've added a skybox (the background (cube) image rendered behind all other elements in the scene), image-based lighting (where an image is used to determine the direction and intensity of a light source) and a directional light (Sun).
+
+Anything added to the scene is referred to as an "entity" (including lights and cameras).
+
+Entities are always added to the scene at position (0,0,0).
+
+The default scene camera is located at (0,0,0) (and is looking at -Z, or "into" the screen), so by adding a cube at (0,0,0), the camera will now be inside the cube. 
+
+We need to move the camera outside the cube so it's visible. 
+
+6. Change the camera orientation
+```dart
+   var viewer = await _thermionViewer;
+    await viewer.loadSkybox("assets/default_env_skybox.ktx");
+    await viewer.loadGlb("assets/cube.glb");
+
+    await viewer.setCameraPosition(0, 1, 10);
+    await viewer.setCameraRotation(v.Quaternion.axisAngle(
+                        v.Vector3(1, 0, 0), -30 / 180 * pi) *
+                    v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
+```
+
+The cube still won't be visible until we add a light to the scene and tell Thermion to start rendering.
+
+7. Add a light and turn rendering on
+```dart 
+    ...
+    await viewer.addLight(
+                    LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
+    await viewer.setRendering(true);
+    ...
+````
+
+8. Run the project
+```
+$ flutter run -d macos
+```
+
+> You may experience a noticeable delay the very first time you run the project. Don't panic, it's not frozen! This is due to the build system downloading the prebuilt Filament binaries from Cloudflare, which can take some time (particularly on Windows). These binaries will be cached after first download, so subsequent runs will be much faster (though every time you run flutter clean, the binaries will be re-downloaded).
