Error LateInitializate FilePicker.platform.pickFiles() web production

[Felixmda]

Before creating an issue, make sure that you are on the latest file_picker version and that there aren't already any similar opened inssues. Also, check if it isn't described on the Wiki, specially on Troubleshooting page.

Also, sometimes a simple flutter clean and flutter build again with latest file_picker version, may end up by fixing cached issues, so I encourage you to first do so.

This problem goes away if I turn off optimizations i.e., flutter build web --dart-define=Dart2jsOptimization=00

        await FilePicker.platform.pickFiles(withData: true);

async method is needed.

Experiencing the same issue here. When I was running it locally, It was running fine. But when I deployed my project to production on firebase hosting. It started giving the above error.

Flutter clean and push again solved!

Same problem here. Workaround applied compiling with flutter build web --dart-define=Dart2jsOptimization=00
Without that option we get the same error on production
