Additional Information

This is a breaking issue that has halted development as we can't test any new work. Please assign the highest priority.

I experience exactly the same issue after yesterday's flutter update.

[YsquanirSq]

Same for me, started happening after the Flutter upgrade yesterday. Same build error.

[CONONIC]

Also experiencing this exact issue

[ajaniewiem]

Are you using one of these dependencies: device_info_plus package_info_plus share_plus? I found out that I only have these custom dependencies that use win32 and they might be the reason.

[itsstevenliu]

Same issue. I'm not using - here are my dependencies

[ajaniewiem]

I updated my dependencies to the following and the local run is working again 🎉 share_plus: ^10.0.2 package_info_plus: ^8.1.0 device_info_plus: ^11.1.0

I recommend you check all your dependencies if they use win32 and update them. You can easily do this by going to Settings > Project Dependencies > Custom dependencies and go to the pub.dev by pressing the icon for each of them. Then check the dependencies of this package in the right column.

Hi @everyone,

Could you please try the solution that @ajaniewiem mentioned and let us know if it works for you?

[whatsake]

I had the same issue i.e Local/Pub/Cache/hosted/pub.dev/archive-3.4.10/lib/src/bzip2/bzip2.dart:7:7: Error: Method not found: 'UnmodifiableUint32ListView'.

What did was to add the latest archive package to my project https://pub.dev/packages/archive/versions/3.6.1.
Turns our that after the flutter update, I didnt even have the archive package anymore.

This sorted my issue! Hope it does for you as well!

[itsstevenliu]

@paulperez-dev, I checked all my dependencies and none of them directly use web32. The only dependency which used another dependency that relied on web32 was html_editor_enhanced: ^2.6.0 which relied on file_picker: ^8.1.3

However adding the latest archive package like @whatsake suggested helped made local run work

[iwanwmys]

Same issue, the solution from @whatsake seemed to work for me.

[Severinius-MUC]

Solution from @whatsake worked for me. Thanks

[jaymutzafi]

Forgive my ignorance, how do i add this package?

I first tried adding things here but it errors for anything I try:

I then tried adding this but I still can't build local run and get the same error with Uint8ListView:

Any explicit instructions would be appreciated.

[Alezanello]

Jay you can add it in any custom action you have like this:
