dart - Find and version bump outdated packages in Flutter (across major versions)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 with built_value:

dependencies:
  flutter:
    sdk: flutter
  built_value: ^5.0.0

When built_value is updated to version ^6.2.0 is there a way to upgrade past the major version so the pubspec.yaml is updated to:

dependencies:
  flutter:
    sdk: flutter
  built_value: ^6.2.0

I know I can manually check each package for major versions, but it would be helpful if it was automatic.

With the latest beta versions of Flutter (v1.17) there is now a pub command to check for outdated dependencies, e.g.

$ flutter pub outdated -h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

Usage: flutter pub outdated [<arguments...>]
-h, --help    Print this usage information.

Run "flutter help" to see global options.

and this gives output like:

$ flutter pub outdated

1 upgradable dependency is locked (in pubspec.lock) to an older version.
To update it, use `pub upgrade`.

4  dependencies are constrained to versions that are older than a resolvable version.
To update these dependencies, edit pubspec.yaml.
