The search UI also supports filters. On a wide screen, the filter options will appear to the left of the search results. On a non-wide screen, to open the filter options, click the filter icon to the right of the search bar. To filter by Dart or Flutter support, expand the SDKs section, then select the SDK you are developing with.

To filter by platform, under the Platforms section, select all platforms you intend to support. To filter by platform, under the Platforms section, select all platforms you intend to support. To filter for only packages with OSI approved licenses , expand the License section, then select OSI approved . To filter for only packages with OSI approved licenses , expand the License section, then select OSI approved . For other filters, such as including unlisted packages, expand the Advanced section. For other filters, such as including unlisted packages, expand the Advanced section. When you search for a package, the search algorithm first applies filters , and then considers only the packages that aren’t filtered out and that match the search query. Because packages contain a lot of text (including documentation comments and identifiers from source code), common words can match many packages. To find the most relevant search results, the algorithm ranks packages using a combination of the following parameters, listed in order of relative importance: Search query relevance of the following: Package name Description README Documentation comments and identifiers Search query relevance of the following: Documentation comments and identifiers Package download count and like count Package download count and like count Pub points , which are based on factors such as these: Adherence to Dart file conventions Presence of documentation Up-to-date dependencies Language feature support Pub points , which are based on factors such as these: Adherence to Dart file conventions Presence of documentation Up-to-date dependencies Language feature support These parameters are normalized, weighted for relative importance, and combined to form an overall score for each search result; this score determines the default order of the displayed search results. The code for normalizing and weighting parameters changes occasionally. You can find it at github.com/dart-lang/pub-dev . Legacy packages # pub.dev does not expose packages that support only Dart SDK 1.x in search results or in listing pages. However, one can access these packages through their package page ( /packages/<pkg> ) and pub client can download them. To search for such packages, include is:legacy in the search query.
