Instead of manually updating dependencies in a pubspec.yaml file, use the update-packages CLI tool:

To update all dependencies: ​

flutter update-packages --force-upgrade

To pin a dependency: ​

Sometimes you need to prevent a dependency from being updated when you run flutter update-packages --force-upgrade.

In that case, first pin the dependency in kManuallyPinnedDependencies and a include a comment with a link to an issue to unpin the dependency.

You can then re-run flutter update-packages --force-upgrade.

To update a single dependency for cherrypicks: ​

Sometimes you need to update a single dependency as a cherrypick to a release candidate branch.

In that case, you can run:

flutter update-packages --cherry-pick-package=[pub package name] --cherry-pick-version='[pub package version]'
