Error : "Synchronous waiting using dart:cli waitFor"

[Skyost]

Hey,

Using the provided command at the bottom of the README, I get the following error :

> dart run flutter_iconpicker:generate_packs --packs material
Building package executable... 
Built flutter_iconpicker:generate_packs.
Unhandled exception:
Synchronous waiting using dart:cli waitFor and C API Dart_WaitForEvent is deprecated and disabled by default. This feature will be fully removed in Dart 3.4 release. You can currently still enable it by passing --enable_deprecated_wait_for to the Dart VM. See https://dartbug.com/52121.

Oh, and as the error message suggests, it's possible to run the command using :

Thank you @Skyost and @tkortekaas for your hints here.

I will focus on this and fix this bug in the next release.

Bug is fixed. A new version will come today.

[Ahmadre]

Fixed with the new version: 3.4.5. Let me know if this solved your error (consider re-downloading your pub package)
