Ah, pub—the unsung hero of Dart and Flutter development. It’s that quiet little tool you only remember when:

• Your app refuses to run because flutter pub get was just a suggestion, right?
• You accidentally typed pub get instead of flutter pub get and now question your life choices.
• A dependency update burns your project to the ground, and you wonder if pub is just a prank by the Dart team.
