Web:Uncaught Unsupported operation: Platform._operatingSystem #1484

Open mokanus opened 2 months ago

mokanus commented 2 months ago

Describe the bug The local operation is perfect, and when I use Flutter run -- release, it is also possible. However, when deploying and accessing Flutter build web, errors may occur

Platform

Platform OS version MacOS：14.2.1 (23C71) Chrome: 123.0.6312.87（正式版本） (x86_64)

How are you picking? I just trigger by one button.Just like: image then: image

After testing this logic, I found an error occurring in the part where the file retrieval is opened, which is the location shown in my screenshot. The issue is that when I click the button, there is no response, and the console displays this error log.

I fixed by clean cache.

Is there a specific reason for this to happen? I can pick files without any problem in debug mode but when I build the project for flutter web it gives me this error.

omensight commented 2 months ago

I see that when I specify the type it stops working in production: FilePickerResult? result = await FilePicker.platform.pickFiles( dialogTitle: LocaleKeys.pickBranchLogo.tr(), type: FileType.image, ); It works well without specifying the type.
