Find and version bump outdated packages in Flutter (across major versions)

Question

Is there a way to list and update packages that have crossed a major version in pubspec.yaml? (like this method used in NPM)

E.g. when the pubspec.yaml file has this

Flutter currently doesn't provide such a feature.
There might be 3rd-party packages that do that. The only one I know is den (https://pub.dartlang.org/packages/den), but this one is not maintained since quite some time and can't be used with recent Dart or Flutter versions.

What might help is to at least get a list of dependencies where newer versions are available.

Upvote https://github.com/flutter/flutter/issues/12627 for that.

In the meantime the workaround mentioned in https://github.com/flutter/flutter/issues/12627#issuecomment-400037072 can be used

Set FLUTTER_ROOT to your Flutter install directory and run pub upgrade. (this requires the Dart SDK to be installed in addition to the Flutter SDK)

$ export FLUTTER_ROOT="/Users/my_user/flutter"

$ pub upgrade
