Description

I just updated to the latest Visual Studio version and this occured on Flutter 3.24.3 and then I upgraded to 3.24.4 and it was still there. Been running this on every project between tries:

Global

dart pub cache clean --force
flutter update-packages --force-upgrade

Once per project

flutter clean
flutter pub upgrade
flutter pub get

And then I tried adding a simple project with just the firebase_auth package and it simply did not work.

.NET / Visual Studio Versions

dotnet --version = 9.0.100
Visual Studio Community 2022 17.12.0

Will try to rollback to previous DOTNET / VS version to see if there's any change.

Reproducing the issue

flutter create fb_test
cd fb_test
flutter pub add firebase_auth
flutter build windows --debug

Firebase Core version

3.7.0

Flutter Version

3.24.4

Rolled back my version of Visual Studio to 17.11.5 with dotnet version 8.0.403.
Except a million warnings it successfully builds.
No changes to my flutter pub deps -- --style=compact output

[guilhermeeng99]

same here

[tranhuudang]

Haven't see any attempts to fix firebase on windows. My app crash often and still has no clue why or how to fix it. I checked for new update of firebase continuously and what I see is almost like zero fix.

Same Issue.
I tried lot nothing helps.

I tried following solutions.

1. Reinstall the VS2022
2. Downgrade the flutter
3. Flutter_Auth plugin tried versions from 4.16.0 to 5.3.3

Same!

[uditrugman]

same, but this also started failing on github actions when building for windows

@thedeukalion - thank you for confirming that reverting Visual Studio/Dot not version is a way to circumvent this issue for now 🙏

i have the same problem if any one solve it, please help me

Will the issue be fixed for dotnet 9?

[russellwheatley]

@PrimeTheFirst - I have no idea I'm afraid. I don't have dotnet installed on my machine

[AbdelaliAmine]

how do you rollback to the version 17.11.5 of visual studio?

[PrimeTheFirst]

I see. Is this a flutter auth issue or a visual studio issue? Any idea when it might be fixed??

how do you rollback to the version 17.11.5 of visual studio?

From what I understand you can only rollback if you have upgraded it from a previous version before. Otherwise Microsoft archives have 17.11.5 update download links for the exe, which isn't working for me. It just says preparing and then closes
@thedeukalion Please guide.

On our side, we managed to workaround the issue on Github Actions with the following steps :

[kaansagtas]

I have the same error. I tried almost everything but couldn't solve it. I just couldn't downgrade the Visual Studio version because it was a new installation and there was no old version already.

@PrimeTheFirst - I have no idea I'm afraid. I don't have dotnet installed on my machine

I see. Is this a flutter auth issue or a visual studio issue? Any idea when it might be fixed??

Is there any progress?

Mine is Visual Studio Community Edition,
As per microsoft forum, they clearly mentioned that community edition could not be downgraded.

[PrimeTheFirst]

Can this issue please be resolved ASAP or can we at least know if a fix is being worked upon and maybe a possible timeframe for its completion? It's affecting a lot of developers and is completely halting development.

After Visual Studio rollback, I solve this problem. Please consider the below link for your roll back.

Hey guys,

This solved the problem for me:

1- Uninstall Visual Studio.
2- Download the installer and execute from PowerShell this command to install the version 17.8:
.\visualstudiosetup.exe --channelUri https://aka.ms/vs/17/release.LTSC.17.8/channel

This worked for me while waiting for package solution to support latest visual studio

FIX: Rollback your Visual Studio version from the Visual Studio installer. Uninstall.NET9 as well. Run flutter clean -> Remove-Item -Recurse -Force .\windows (optional) -> flutter run (or just rebuild the program)

[StephanTLavavej]

I'm a maintainer of Visual Studio's C++ Standard Library implementation. This was an intentional change - we merged microsoft/STL#4713 to unconditionally implement P0608R3 "Improving variant's Converting Constructor/Assignment" (a C++20 paper) in C++17 mode too. This now matches what GCC/libstdc++ and Clang/libc++ do, and is generally a highly desirable change for variant users, although it can have source-breaking impacts as in this case.

Instead of downgrading your VS IDE, or using an older MSVC toolset within the newer IDE, the correct long-term fix is to patch encodable_value.h's usage of std::variant so that it works with P0608R3's changes.

[StephanTLavavej]

I have a fix (see linked PR) if anyone affected by this issue would like to try it with VS 2022 17.12.

Two days ago I sat down to do a small Flutter project (first in about a year). I made sure everything was up to date, including MSVS Community. I use Windows and I generated the default Flutter app and added only two lines to the pubspec, firebase_core and firebase_auth. But it wouldn't build! I've spent the last two days assuming I had a config issue. I even wiped my machine and reinstalled Windows. I only now found this issue on GitHub.

@Mohamed-Reda7 I can't thank you enough. Reverting to MSVS 17.8 completely resolved the issue.

@StephanTLavavej My MSVS version (the one that did not work) was 17.12.3, so the issue doesn't seem to be fixed in VS 2022 17.12.

I'm such a fan of Flutter, but this was such a bad experience. The default generated app doesn't work with one of the most popular plug-ins (firebase auth) for one of the most popular OSs (Windows). I'm not a professional developer, more of a hobbyist, but I'm a huge fan of Flutter and would love for this issue to be escalated and get the attention I suspect it deserves. If someone can tell me how to do that I'm happy to do the legwork.

[StephanTLavavej]

@gh-pap This was exposed by a VS change, but it was not a VS bug, and VS isn't being patched for this. Instead, it was a flutterfire bug, and I contributed a fix which was merged 2 weeks ago - see above. I investigated and fixed this within a day of it being brought to my attention.

If you can't wait for the next release of flutterfire, you could potentially build its latest sources. Once you can pick up the fix, you should move your MSVC toolset forward and stop pinning to an older version. (As for working around it, (1) you can use the newest VS IDE while selecting an older MSVC toolset, and (2) you can use a toolset as new as 17.10, it doesn't have to be as old as 17.8. It was the 17.12 toolset that exposed the flutterfire bug.)

would love for this issue to be escalated and get the attention I suspect it deserves.

This got attention at extremely high levels within Microsoft. A Corporate Vice President/Distinguished Engineer in Windows emailed my quad boss (a CVP himself) in DevDiv about this compiler error, and it was quickly routed down to me. (I am a mere Principal SDE, maintaining MSVC's STL for 18 years.)

[gh-pap]

Aha, I understand now. Thanks for fixing the issue! 🙏🙏🙏 I wouldn’t trust myself to install a pre-release. I’ll just remain on the older MSVC until the fix is released (then upgrade to the latest MSVC). Does anyone know which versions of firebase_core and firebase_auth (I assume both are needed) will include Stephan's fix?

[ZiyadF296]

It will probably be mentioned in the changelog in an upcoming release, probably the very next release.
