How this service works
pub.dev package info - latest Dart or Flutter package version, license, likes, 30-day downloads, pub points, dependencies and platforms
Output
Returns structured pub.dev metadata for the requested package: latest version string, SPDX license identifier, number of likes, 30-day download count, pub points score, list of dependencies, and supported platforms (e.g. Android, iOS, Web, Linux, macOS, Windows).
Example use cases
Vetting a Flutter dependency
“Before I add 'riverpod' to my Flutter project, can you pull its pub.dev stats — latest version, license, pub points, and 30-day download count — so I can decide if it's well-maintained?”
Comparing package popularity
“What are the likes and 30-day downloads for the 'provider' package on pub.dev? I'm trying to gauge how popular it still is compared to alternatives.”
Checking platform compatibility
“Does the 'shared_preferences' package support Flutter Web and Linux? Can you fetch its pub.dev page and tell me the supported platforms and latest version?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/registry/pub/:name?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date pub.dev package metadata (version, license, popularity signals, platform support) without scraping pub.dev yourself. Prefer it over manual browsing or GitHub README parsing when you need machine-readable stats for Dart or Flutter packages specifically.
Side effects
- Package name not found on pub.dev — returns 404 or empty result
- Misspelled package name yields no results
- pub.dev upstream unavailable — may return timeout or 5xx error
- Package exists but has been discontinued or unpublished — may return stale or missing data
