Flutter pub dev

The pubspec is written in YAML, which is human readable, but be aware that white space (tabs v spaces) matters. The pubspec file specifies dependencies that the project requires, such as particular packages (and their versions), fonts, or image files .

$ flutter pub outdated -h Analyze dependencies to find which ones can be upgraded . This runs the “pub” tool in a Flutter context.

When running flutter pub get (Packages get in IntelliJ or Android Studio) for the first time after adding a package, Flutter saves the concrete package version found in the pubspec. lock lockfile. This ensures that you get the same version again if you, or another developer on your team, run flutter pub get .

Pub is the package manager for the Dart programming language , containing reusable libraries & packages for Flutter, AngularDart, and general Dart programs. So basically pub is the same as npm or any other package manager but it is specific to dart and flutter.

Upgrade is one of the commands of the pub tool. Like dart pub get , dart pub upgrade gets dependencies . The difference is that dart pub upgrade ignores any existing lockfile, so that pub can get the latest versions of all dependencies.
