flutter pub is the command-line interface for Pub, the package manager in the Dart and Flutter ecosystems.

It manages dependencies listed in pubspec.yaml, resolves transitive dependencies, downloads packages from pub.dev or other sources, and maintains a pubspec.lock file for reproducible builds.

Key functions include fetching packages (pub get), upgrading them (pub upgrade), inspecting dependency trees (pub deps), checking for outdated packages (pub outdated), and running package executables (pub run).

Pub uses a shared cache (~/.pub-cache) to avoid redundant downloads. It supports version constraints, dev dependencies, and global activations for CLI tools.

Essential for Flutter apps, it integrates seamlessly with flutter create and build processes, ensuring consistent environments across development, testing, and production.

Usage typically follows editing pubspec.yaml, then running flutter pub get. Supports offline mode and verbose logging for troubleshooting.

Requires Flutter SDK in PATH; run flutter doctor first. Cache can grow large (~/.pub-cache). Offline mode limited without prior fetches.

Pub originated in Dart SDK (2013); integrated into Flutter at launch (2017). Evolved with Flutter 1.0 (2018) for mobile/web/desktop support.
