With the latest beta versions of Flutter (v1.17) there is now a pub command to check for, and update, outdated dependencies.
To check for outdated dependencies, run:
$ flutter pub outdated -h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Usage: flutter pub outdated [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$ flutter pub outdated

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
