Find and version bump outdated packages in Flutter (across major versions)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

Answer 1

With the latest beta versions of Flutter (v1.17) there is now a pub command to check for outdated dependencies, e.g.

$ flutter pub outdated -h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Usage: flutter pub outdated []
-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$ flutter pub outdated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.
