FAQs

Does this require an API key or login? No. The Pub.dev public API is freely accessible without authentication.

What is the trending mode? Trending mode queries Pub.dev for Flutter SDK packages sorted by popularity score, giving you the most widely-used packages in the Flutter ecosystem.

How does the search mode work? Pub.dev returns a page of package names per request. For each name returned, the scraper fetches the full package details, score, and publisher in parallel. This ensures you get complete metadata for every result.

What are pub points? Pub points (0–160) are awarded by Pub.dev based on documentation quality, code conventions, platform support, and other quality criteria. Higher scores indicate better-maintained packages.

Which fields are always present? package, pubDevUrl, and scrapedAt are always populated. All other fields are omitted if not available for a package.

Can I filter by SDK (Dart vs Flutter)? Use the search query with SDK filters: e.g. sdk:flutter or sdk:dart. Combine with a keyword: "flutter dio".

What is a publisher ID? Publisher IDs are verified domain names registered on Pub.dev (e.g. flutter.dev, dart.dev, google.dev). They certify that packages are officially maintained by that organization.
