Dart & Flutter Package Info (pub.dev)

pubdev/package-info

The latest release of one Dart or Flutter package on pub.dev: version, description, links, topics, SDK and Flutter constraints, runtime dependencies, archive URL and SHA-256, whether the package is discontinued and what replaced it, plus one line per published version with its date and retracted flag. Data from pub.dev, https://pub.dev, modified by Eden Engine (fields renamed and reduced); not an official pub.dev or Google product.

Data source

pub.dev

Package data from pub.dev, https://pub.dev, the package repository for Dart and Flutter, fetched through its public API. Modified by Eden Engine: fields renamed and reduced (the other versions' pubspecs and the legacy author field are dropped, and versions are summarised to one line each) and served by Eden Engine; this is not an official pub.dev or Google product.
