[cheny09]

Add these lines to your pyproject.toml file

[tool.flet.flutter.pubspec.dependency_overrides]
file_picker = "8.1.4"

[omamkaz]

Add these lines to your pyproject.toml file

[tool.flet.flutter.pubspec.dependency_overrides] file_picker = "8.1.4"

It's working, thanks :)

[ndonkoHenri]

Thanks for the solution and feedback.
Will bump the version of file_picker we use to 8.1.4.

Upstream issue: miguelpruivo/flutter_file_picker#1643

[FeodorFitsner]

Updated app build template with file_picker: 8.1.4

Weird, I'm getting "registrar" error again with file_picker: 8.1.5. Regression?
