Hi there folks,
First of all this is an amazing plugin and opens up a hell lot of possibilities. Kudos to devs.
I want to work on AR so used the Flutter-Unity ARFoundation example and after a bit of hassle , it worked like charm. :)

I have been working in Unity for quite some time and have quite an idea about how it works.But I am kinda new to the flutter world.
I basically want use the Flutter UI to pass data to Unity and then Unity to work on based of the inputs. It will be really great if you can give me an high level view of the communication happens. For example if I want to make a simple AR app with image scroll at the bottom of the screen and the user can slide an(through flutter UI) will be passed to Unity so that we can spawn the selected object.

Once again, kudos to the devs. I hope to contribute to this widget and make it better ;)

Hey guys, does anyone have the same issue snowballdigital/flutter-unity-view-widget#145 ?

@FiddlePlus

Hey, guys! I have a question if that's ok :) So, I want to create pretty large catalogue app with lots of 3d models (about 20-30) What would be the best way to go about it using 'flutter-unity'? I was thinking maybe I could pass path as a string to 3d model via navigator argument (widget with 'flutter-unity' is on the destination screen), but I don't know if that's possible (or even advisable) to do. Or maybe just add bunch of 3d models inside unity project and show/hide them via arguments. But again - I don't know if that's possible. So.. I would appreciate any form of advice or hint about what to do here :)

@FiddlePlus , You could use https://pub.dev/packages/flutter_unity_widget to embed your Unity module into your flutter app, save all the 3D models as different scenes, and then pass arguments to launch whichever scene you want to launch via flutter_unity_widget's method - postMessage(String gameObject, methodName, message).

I'll try it, thanks! And report back with results!

Hi guys! I have a favor if that's ok! So I am new at this and I have been really confused to how to communicate between flutter and unity. Is there anyone willing to share their example source code using flutter & unity? Just for me to understand the code and how it communicates between each other. Really appreciate it guys if its not a hassle. Thank you!

Hi guys.

Can you help me with one thing? How can I return the system buttons and status bar after closing the screen with a UnityWidget?

I'm talking about this issue.
"Using AR will make the activity run in full screen (hiding status and navigation bar)."

Hi everyone, can someone show how can we add the .aar modules to the projects? i could add "unity-classes.jar" file by using right click -> add as library. But, there is no such option other than "make module" which does nothing when clicked.
Please help /\

Jatin Pawar

@Jatin-Pawar

Hi @AksAman,
Kindly have a look at snowballdigital/flutter-unity-view-widget#49

If still, you are not able to get started, then kindly message here and I will try to help you out.
As per your specific question, to include the .aar module related to AR, go to File->New Module-> Import .jar/.aar-><Browse and select your .aar file>.
This will make import the specific .aar and will make a separate folder for it. Make sure you drag and drop the newly created folder under the android folder.

Hope this helps :)

Hey guys, I already read every issue related to iOS, but somehow I am not able to build for iOS 13:

Undefined symbols for architecture arm64:
"_onUnityMessage", referenced from:
_NativeAPI_onUnityMessage_mD44345499E1125EA37D67E2892D48D89B448B012 in Assembly-CSharp.o

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am trying for weeks to build for ios

I just want to setup plain ios, not AR

@giovannowarli

Hey @Ahmadre I am experiencing the same problem. Idk how to solve it, any ideas?

Giovanno Warli

@giovannowarli

Actually @Ahmadre, for this, all you have to do is upgrade your Unity Version, I tried using 2020.1.1.1f1

and it worked

gbo999

@gbo999

i get this problem:[FATAL:flutter/shell/platform/android/platform_view_android_jni_impl.cc(942)] Check failed: CheckException(env).

@gbo999

my app crashes on emulator but work on physical device how can i make it work on both?

Giovanno Warli

@giovannowarli

Hey @gbo999 ,

It will work. 2. It sends data thru messages. 3. I think it only can run on physical device, it cant run on emulators

@/all I have an unpublished version of the library which fixes alot of your issue. Its a complete rewrite and sponsored by a Company that has interest in the library. Hopefully in a few days I will publish it and so you guys be patient. It has alot of unity exposed APIs abd very stable with easier integration

In the next release you won't have to import unity classes as a standalone module

Vyankatesh Dasari

@Mrityunjay1198

Hello, I'm trying a AR in unity. So for best GUI experience i want to use flutter interaction in unity so how i can add flutter support to unity . I'm using Unity-2019.4.9f1 , their are some errors in running basic flutter app : Error: PowerShell executable not found.
Either pwsh.exe or PowerShell.exe must be in your PATH.

@subjectdenied

@juicycleff : any news about the rewritten library?

Hey guys! Any news related to the new library? I am also having problems with popping the unity context and i am interested if i shall wait for the new package release.

@MonkeyD-IchiJou

Nice, cant wait for the new version, else I might need to create a new one myself too

Tudor Axinte

@TudorAxinte

lost 3 days trying to integrate this piece of crap

I might as well build everything in unity instead

A problem occurred evaluating project ':flutter_unity_widget'.

@mihaelpuljak

Hey just wanted to thank you guys for your hard work. flutter-unity-view-widget 2.0 is just what I wanted. I managed to integrate and test today. Fantastic job - navigation Flutter - Unity works like charm now.

P.S. also much better with new unity library approach, instead of manually inserting new projects for each new library

Jatin Pawar

@Jatin-Pawar

Hey @mihaelpuljak
I am happy to hear that you were able to test it out and it worked. I am also trying to play around with it, it would be really helpful if you can guide me to the resources/steps you followed to get the examples working.
PS: I will be developing on Android.

Looking forward to hearing from you @mihaelpuljak
