build-backend = "setuptools.build_meta"

[tool.flet]

Remove this:

[tool.flet.flutter.dependencies]
flet_audio = "0.81.0"

Having the extension in your deps ("flet-audio>=0.81.0") is sufficient.

Then, delete the build directory (or use --clear-cache) and rebuild.

Thanks for the prompt reply! Here is what I tried:

• Removing the tool.flet.flutter.dependencies + >=0.81.0 produces the same error. Note that though superfluous, this toml setup worked until today.
• Rerun the yesterday's nightly that passed yesterday with dependency >=0.80.5 and it now fails. (obviously this installs 0.81 but good to check the same code)
• Pinning to 0.80.5 works like a charm.
• I wiped all caches by dropping them from Github Actions and rebuilt with 0.81.0 and it failed.

Do you think the outputs of flutter doctor are related here or safe to ignore?

[ndonkoHenri]

We tried and were able to repro the issue, and patch it immediately. Thanks for reporting!

Please rerun your apps, and let us know.

[FeodorFitsner]

Yeah, remove build dir first and then re-build.

Thanks guys, I've seen the message and will test it probably tonight.

Hi @flet-dev team,

First of all, thank you for the great work on Flet — it's an amazing framework!

I'm experiencing the exact same issue described here (#6210) with Flet 0.81.0 on Windows (though the reporter mentioned APK/Android, the error is identical).

My setup:

• Flet: 0.81.0 (fresh install in a clean virtualenv)
• Flutter: 3.41.2 (stable, doctor shows all green)
• OS: Windows 11 Pro
• pyproject.toml dependencies: "flet>=0.81.0", "flet-audio==0.81.0" (or >=)
• No local/path installations or editable modes for flet-audio

Error (same as in the issue):

[FeodorFitsner]

@GalileoAlmeria it should be fixed now. Delete build directory inside apps folder and re-build the app.

[GalileoAlmeria]

@FeodorFitsner Thank you so much to the Flet team for the quick fix!

I just tested with the updated version / applied solution and the build now works perfectly for both Windows and Android—no more "from path vs hosted" conflict.

I really appreciate how fast you looked into this and resolved it. Flet continues to be an excellent framework, and responses like this show how much care and attention goes into the project.

Thank you again for your excellent work and support!

Best regards

[FeodorFitsner]

Thanks for your support and kind words!

[datumbox]

@ndonkoHenri @FeodorFitsner I've tested it again and everything works.

First of all thanks so much for the help on this and the prompt responses. Second, just wanted to echo @GalileoAlmeria comments regarding how amazing work you've been doing and my gratitude for building Flet. Open-source developers often don't get enough credit about the work they are doing... Massive massive thank you for the amazing library you built.

I'm not going to close the issue because I see @ndonkoHenri has an open PR linking to it. I trust you can close it yourself when you are happy with it.
