Failed to build intl_utils:generate

[bahadirarslan]

My "Extract To ARB" function broke after upgrading Flutter 3.13

When I try to use Extract To ARB function or save .arb file I see this output.

INFO: Generating localization files for the 'mylog' project...
Failed to build intl_utils:generate:
../../../.pub-cache/hosted/pub.dev/watcher-1.0.2/lib/src/constructable_file_system_event.dart:7:57: Error: The class 'FileSystemEvent' can't be extended, implemented, or mixed in outside of its library because it's a sealed class.
abstract class _ConstructableFileSystemEvent implements FileSystemEvent {
                                                        ^
exit code 1

Here is my flutter doctor -v output

Do you have any suggestions?

Hi @bahadirarslan,

There seems to be a cache-related issue with Flutter after upgrade.

Could you please let me know which version of the intl_utils package you're using?

flutter pub global list

A potential fix is to reactivate the intl_utils package. It might help resolve the issue.

flutter pub global deactivate intl_utils
flutter pub global activate intl_utils

Yes! I was looking for this. Thank you, I couldn't find the renew caches. Now it works
