final documentation =  await client.documentation('pkg_name');

Like Packages

All requests for likes require pub.dev authentication.

List liked packages

Displays list of of packages you have liked. Returns list of packageLikes

final likes =  await client.listPackageLikes();

Package Like Status

final like =  await client.likePackageStatus();

Like a Package

Likes a package. The method returns packageLike payload

final like =  await client.likePackage('pkg_name');

final like =  await client.unlikePackage('pkg_name');

Search Packages

Search for packages on pub.dev. Will return the packages that match the query. You can filter the search to a specific publisher, or packages with a certain dependency.

final results =  await client.search('query', publisher:'publisher_id', dependency:'dependency_name');
// Returns the packages that match the query
print(results.packages)

Paging Search Results

You are able to page search results.

final results =  await client.search('query');
final nextResults = await results.nextPage();

print(nextResults.packages)

If you want to retrieve a specific result page you can call the page parameter directly.

final results =  await client.search('query',page:2);
print(results.packages)

Utilities

Update Notification

Custom Update Notification

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(
    package,
    currentVersion: currentVersion,
  );
  final latestVersion = latest.latestVersion;

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

  return latest.needUpdate;
}
