final latest =  await client.checkLatest('pkg_name', currentVersion:'current_version');
// Returns the packages that match the query
print(latest.needUpdate) // bool if package needs update
print(latest.packageInfo) // Returns information about the package
print(latest.latestVersion) // Returns the latest version of the package.

This package has a helper method if you want to notify users of your CLI of a newer version. In order to check for update you have to provide currentVersion.

Check Update Printer

Snippet for implementation of check update functionality

/// Checks and prints if [currentVersion] of a [package]
/// is not the latest version.

Future<bool> checkUpdatePrinter(
  String package, {
  required String currentVersion,
}) async {
  final latest = await PubClient().checkLatest(
    currentVersion: currentVersion,
  final latestVersion = latest.latestVersion;

  if (latest.needUpdate) {
      'Update Available for $package: $currentVersion → $latestVersion',
    print('Changelog: ${latest.packageInfo.changelogUrl}');

  return latest.needUpdate;
