Also, is someone also experiencing this? juicycleff/flutter-unity-view-widget#281

Hello Cristian, same issue here .. I tried to use unload in dispose, but when I try to go back to my screen where there is my unity, I am not able to launch it

Were you able to have the correct behavior ?

Hi, guys do we still need to remove vulkan from the Graphics APIs in Unity in the recent versions ?

Hi! Do you guys know how it would be possible to embed a Unity app into flutter desktop? I couldn't export the unity project as I did for flutter mobile

Simran Rout

@simranrout

heyy everyone I am working on Arkit , I wanted to place an object using the longitude and latitude , how can I do that

Tiebo

@Tiebo

Hey everyone. This package looks very interesting. Can someone tell me please what the update frequency is between flutter and unity? Concrete example: I have a 3d model airplane which is flying in unity. I want to pass the controls from flutter to unity, let the movement be calculated and then get the new position data back from unity to flutter. Is this realistic? Is there latency? And what is the frequency of incoming and outgoing data? Thanks for your answers.

Steven Jr.

@Witchd0ct0r

@Tiebo Well I don't think there would be a regular update frequency in flutter. I assume you want to update some info with the flight data from unity in your flutter framework. With unity you can call a flutter function with setstate but that will rebuild your widget. Or you can set up a data stream in flutter which will update "itself" every time unity sends new data. If you want to measure the exact latency you could set up a timer in flutter and measure the time between the incoming unity function calls. Also you will have to keep in mind unity's frame time (Time.deltatime). You can get started with streams here: https://medium.com/flutter-community/flutter-stream-basics-for-beginners-eda23e44e32f

Steven Jr.

@Witchd0ct0r

@simranrout In the example flutter-unity-widget there is an example function how to send data from flutter to unity. If you problem lies in flutter-unity communication. In unity most of the time you just Instantianate(Gamobject, Vector3, Quaternion)

@nmfisher

@ratchapongbz_gitlab is that needed on master HEAD? I just ran grep on my (working) iOS folder and couldn't find any reference

Luis Pulido

@nosmirck

hello! can anyone shed some light on this? juicycleff/flutter-unity-view-widget#358

Steven Jr.

@Witchd0ct0r

@nosmirck as far as i understand your problem you dont really have to keep the plugin "updated" on all projects. Of course you have to include the package in your pubspec file. Currently there is a unity script that compiles the unity project for the plugin. If you look up the script in the example unity project you will be able to edit to suit it for your needs. In short you have to edit it to compile the project for all of your flutter solutions. This way if you make changes in your unity project you will be able to compile it for all of your flutter programs in one step.

Luis Pulido

@nosmirck

yeah, the issue is that the project is over 1GB size and there are 7 apps, even versioning control is becoming a nightmare. if we had just one plugin that we can reference from local (path: ../plugin) and in that plugin we have all we need so we just use the widget that'd be great. Also, there the potential that we add more apps to this. That's why it's very important that we have only the plugin locally with the unity project. My idea is keep the unity project in git, the base plugin also in our repo (but we add the unityLibrary in gitignore) and our child flutter projects in independent repos, now, whenever someone works on one of our projects, they just have to clone the unity repo with the base flutter plugin together in one folder at the same level as the project, open the unity project, compile the stuff assets and that's it, if they clone any of the other projects they just need to run it, no need to compile anything else, it should work out of the box

@borzea-recipe

Hello, is the plugin broken for iOS on version 4.1.0-null-safe? There are multiple reports with build issues for iOS: juicycleff/flutter-unity-view-widget#373

Can someone please help to solve with this issue?

Bogdan Orzea

@borzea-recipe

^^^ For the above problem, once the flutter-unity-view is integrated into your project you can never use that Flutter app in an iOS simulator: juicycleff/flutter-unity-view-widget#188

Hey guys,
My unity app doesn't receive inputs, i'ts wrapped in MaterialApp -> SafeArea -> Container -> UnityWidget,
What could be a possible reason? Couldn't google anything about it

I mean, taps don't reach unity app

Egor Gumenyuk

@boo1ean

@boo1ean

Even when it's not wrapped in anything

Egor Gumenyuk

@boo1ean

The problem was with Unity's new input system. The legacy system works as expected

Is it ever gonna be available for desktop, if its even possible?

Jehoshaphat I. Abu

@Jehoshaphatia

Hi,

I built an APK in Unity 2020.3 LTS successfully, and run the app on my phone. It showed the scene, as expected. But, after exporting the same Android to be built in Flutter using the plugin in Unity, the Flutter project builds successfully, but the resulting page is just white(Blank without showing any object or even rendering the Unity scene) when the app is run on the phone. Even the communication from Unity that's supposed to show in the log, when my scene is loaded to Flutter isn't showing any of the messages in onUnitySceneLoaded(SceneLoaded sceneInfo).

Does anyone have ideas or facing the same issue? @juicycleff any idea why this could be happening?

Thank you for your time.

What flutter code yiu are using ? I have made game in unity and exported to flutter. There were some issues but everything worked fine

I'm looking for the unitypackage https://raw.githubusercontent.com/juicycleff/flutter-unity-view-widget/master/scripts/FlutterUnityIntegration-v4.unitypackage - does anyone know where this is? The link has died, and it seems like everyone points to it.
