Search | Help | Dart packages

pub.dev supports the following search query expressions:
"exact phrase": By default, when you perform a search, the results include packages with similar phrases. When a phrase is inside quotes, you'll see only those packages that contain exactly the specified phrase.
package:<prefix>: Searches for packages that begin with prefix. Use this feature to find packages in the same framework.
dependency:<package_name>: Searches for packages that reference package_name in their pubspec.yaml.
dependency*:<package_name>: Searches for packages that depend on package_name (as direct, dev, or transitive dependencies).
topic:<topic-name>: Searches for packages that have specified the topic-name topic.
publisher:<publisher-name.com>: Searches for packages published by publisher-name.com.
sdk:<sdk>: Searches for packages that support the given SDK. sdk can be either flutter or dart.
platform:<platform>: Searches for packages that support the given platform. platform can be one of android, ios, linux, macos, web, and windows.
runtime:<runtime>: Searches for packages that support the given runtime. runtime can be one of web, native-jit, and native-aot.
license:<license>: Searches for packages with a specific license. Use license:osi-approved for packages with OSI approved licenses, or use an SPDX license identifier (such as license:bsd-3-clause or license:mit).
is:<tag>: Searches for packages with a specific property:
has:<tag>: Searches for packages that include specific content or metadata:
show:unlisted: Includes unlisted, discontinued, and legacy packages in search results.
updated:<duration>: Searches for packages updated in the given past days, with the following recognized formats: 3d (3 days), 2w (two weeks), 6m (6 months), 2y (2 years).
Tag expressions (sdk:, platform:, runtime:, license:, is:, has:, topic:, and publisher:) can be negated by prefixing them with - to exclude matching packages from search results. For example:
Note that package:, dependency:, dependency*:, updated:, and free-text search terms cannot be negated.
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 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.
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 download count and like count
Pub points, which are based on factors such as these:
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.
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.
