flutter pub command [options] [arguments]

flutter pub manages Dart package dependencies for Flutter projects. It installs, updates, and resolves packages from pub.dev, the Dart package repository.
The tool reads pubspec.yaml for dependency specifications and generates pubspec.lock for reproducible builds. It handles transitive dependencies and version conflicts automatically.
flutter pub enables code reuse through thousands of community packages for networking, state management, UI components, and more.

Version conflicts may require manual resolution. Some packages are platform-specific. Large dependency trees slow first build.

flutter pub wraps the Dart pub tool for Flutter development. The pub.dev repository serves both Dart and Flutter packages, managed through the shared package specification format.
