Cannot pick files on Web

[Gnoucorp]

Hello,
After a recent pub update, I realized that I could not pick files anymore on flutter web.

It seems that the method FilePicker.platform.pickFiles always returns null.

I managed to reproduce it with the example app on branch master (no matter what I pick, I see the text "User has aborted the dialog"). I use Flutter 3.7.0 on windows 11 with VS code, reproduced it on Edge and Chrome.

Same for me, it seems to be triggered by Flutter 3.7.0

(Edit for clarification): It's sporadic, so sometimes it works, sometimes it does not.

Same for me , When i try to run in Chrome ... It works on mobile ...
Error: Undefined name 'FilePickerWeb'. FilePickerWeb.registerWith(registrar) ;

It works for me irregularly, about once every three picks.

(the keyboard error is a Linux error, not related to FilePicker)

Reproduced on flutter v3.7.3 : nothing changed.

Any workaround available ?

What I did in my app was show an error dialog if the result was null, in order to at least indicate something happened. To avoid showing the error dialog when user cancelled the pick, I gave it an onFileLoading callback that set a flag, which was checked before throwing the error dialog.

I just tried to use the web example from the master branch, it's ok.
Is this a problem existing in the released version, and has been solved in the master?

I'm having this issue. It works as expected in debug mode but it doesn't when deployed. It returns null. Any updates or workarounds? Thanks!
