If you know that your package works fine with 1.2.3 of some dependency, then The Dart community uses semantic versioning 1, which helps you know which versions should work. To exclude versions that you know don’t work or haven’t been tested. Wide as possible to give your users flexibility. Your goal is to allow a range of versions as Using your package know which versions of its dependencies they can rely on toīe compatible with your library. Specifying version constraints lets people If it’s an unknown identifier, the dependency is always considered unsatisfied. The Flutter SDK contains a package with the given name.Pub is running in the context of the flutter executable.If it’s flutter, the dependency is satisfiable as long as: The identifier after sdk: indicates which SDK the package comes from. The SDK source is used for any SDKs that are shipped along with packages,Ĭurrently, Flutter is the only SDK that is supported.ĭependencies : flutter_driver : sdk : flutter Publish your main package too, if you want.Change your pubspec to point to the now hosted version of its dependent.Once they’re both working, publish the dependent package.Work on the main package and the package it depends on.Edit your pubspec locally to use a path dependency.

Pub.dev site if it has any path dependencies in its pubspec. Because of this, you cannot upload a package to the Sharing code with the outside world-not everyone can get to Path dependencies are useful for local development, but do not work when Relative paths are allowed and are considered relative to the directory This says the root directory for transmogrify is /Users/me/transmogrify.įor this dependency, pub generates a symlink directly to the lib directory To make that easier, you can depend directly on a packageĭependencies : transmogrify : path : /Users/me/transmogrify Maybe your package itself is still inĭevelopment and is using other packages that are being developed at the Sometimes you live on the bleeding edge and need to use packages that The following YAML code creates a dependency on the transmogrify package If you want to use your own package repository, Transmogrify and works with any version from 1.4.0 to 2.0.0 This example specifies that your package depends on a hosted package named Here’s an example of specifying a dependency:
