Compilation error in VS 2026 18.6.0: C2338 static assertion failed - experimental coroutine headers deprecated (error STL1011)

[yiky84119]

Description

When building a Flutter project that depends on just_audio_windows, the compilation fails with the following error:

Issue 1: Experimental coroutine deprecation error

C:\Program Files\Microsoft Visual Studio\18\Community\VC\Tools\MSVC\14.51.36231\include\experimental\coroutine(37,1): error C2338: static assertion failed: 'error STL1011: The /await compiler option, <experimental/coroutine>, <experimental/generator>, and <experimental/resumable> are deprecated by Microsoft and will be REMOVED SOON. They are superseded by the C++20 and C++23 headers. You can define _SILENCE_EXPERIMENTAL_COROUTINE_DEPRECATION_WARNINGS to suppress this error for now.'

Issue 2: File encoding error for uri_utils.hpp

The uri_utils.hpp file has an incorrect file encoding format. It needs to be saved as **Unicode (UTF-8 with BOM)

Environment

• Flutter version: 3.41.9
• just_audio_windows version: 0.2.3
• Visual Studio version: 2026 18.6.0

Oops, it appears that your issue did not follow the template and is missing one or more required sections. Please open a new issue, and provide all required sections and information.

FAQ:

1. Do I really need to submit a minimal reproduction project for a bug? A: Yes. I prioritise bugs secondarily on how many people are affected, and primarily on whether the bug report is complete, in the sense that it enables me to immediately reproduce it and start working on a fix. If a bug is important to you, the best thing you can do is to provide all requested information ASAP so that I can start looking into it ASAP.

2. I think I supplied all required information, so did the bot make a mistake? A: The bot only checks the section headings, so when you post a new issue, make sure you leave the section headings intact. (Note that because of this, it is even possible to trick the bot by including only the section headings, and then not providing the requested information under each heading. This is frowned upon, and the issue will be closed manually.)
