What does flutter pub upgrade do?

Did you know?

There's a subtle difference between pub get and pub upgrade:

• pub get will get all dependencies, keeping the versions inside pubspec.lock.
• pub upgrade will upgrade all dependencies to the latest non-major version, ignoring the pubspec.lock file.

Also note:

• If pubspec.lock doesn't exist yet, both commands behave identically.
• Neither command updates any dependencies that are locked to a specific version (no caret syntax).
