Same problem here, the Audio-Recorder Sample Code does not work.

[ThreeRiversAINexus]

I can also verify that this error is happening to me too.

[yashasolutions]

same error here - I have tried modifying the code to get it to work but no success

Please specify the platforms on which the issue is faced.

[yashasolutions]

Please specify the platforms on which the issue is faced.

In my case, I am running flet run --android on a linux environment (Linux 6.10.3-arch1-2 flet-dev/flet#1 SMP PREEMPT_DYNAMIC Tue, 06 Aug 2024 07:21:19 +0000 x86_64 GNU/Linux) inside of a venv with Python 3.12.4)

But I am using the app on an android phone.

The error however seems to be related to async support.

I can't even get the sample to work in windows.

I have just updated to 0.25.1 and the issue remains...

I am also having this issue. I noticed that recording is successfully started
