How it works

pubspec-update only parses the dependencies and dev_dependencies blocks of pubspec.yaml. It looks only at packages with a version string on the same line as the package, including any and empty version strings.

# All of these will be processed.
dependencies:
  intl: ^0.15.0
  frogs: any
  transmogrify:
  angular: '>=4.0.0 <5.0.0'
dev_dependencies:
  test: ^1.0.0
# None of these will be processed
dependencies:
  intl:
    path: ../intl
  frogs:
    git: github.com/frog-database/frogs.git
  transmogrify:
    hosted:
      name: transmogrify
      url: http://some-package-server.com
    version: ^1.0.0
dev_dependencies:
  flutter_test:
    sdk: flutter

# Section ignored
dependency_overrides:

It will then read the .packages file to find the latest version of each package, creating the file if it doesn't exist. Using the --get or --upgrade arguments will first run pub get or pub upgrade (or flutter equivalent) before parsing the .packages file.

Safety first

Before making any changes, it will show the user exactly what will change and give them a change to abort.

Limitations

While it can read any version constraints (">=1.0.0 <2.0.0"), it always uses caret syntax (^1.0.0) when updating version constraint. This is because it is the most widely used format and because it is much harder to try and intelligently add min and max versions that consider pre-release and build suffixes.

Specifically, the exact version from .packages is prefixed with a caret (^) to become the new version.
