Find and version bump outdated packages in Flutter (across major versions)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With the latest beta versions of Flutter (v1.17) there is now a pub command to check for, and update, outdated dependencies.

To check for outdated dependencies, run:

$ flutter pub outdated -h Analyze dependencies to find which ones can be upgraded.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  Usage: flutter pub outdated [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$ flutter pub outdated Dependencies                           Current              Upgradable           Resolvable           Latest path                                   *1.6.4               *1.6.4               *1.6.4               1.7.0 permission_handler                     *4.4.0+hotfix.4      *4.4.0+hotfix.4      5.0.0+hotfix.3       5.0.0+hotfix.3  dev_dependencies analyzer                               *0.36.4              *0.36.4              *0.36.4              0.39.7 build_runner                           *1.7.4               *1.7.4               *1.7.4               1.9.0  transitive dependencies asn1lib                                *0.5.15              *0.5.15              *0.5.15              0.6.4 permission_handler_platform_interface  *1.0.0               *1.0.0               2.0.0                2.0.0  transitive dev_dependencies build                                  *1.1.6               *1.1.6               *1.1.6               1.2.2 build_config                           *0.4.1+1             *0.4.1+1             *0.4.1+1             0.4.2 dart_style                             *1.2.9               *1.2.9               *1.2.9               1.3.6  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. 

To update with compatible dependencies, run:

flutter pub upgrade 

or to update with potentially breaking changes, use

flutter pub upgrade --major-versions
