How to develop a Dart library locally?

Issue

I might be having a mental eclipse, but it’s hard for me to do the simplest thing: write a simple library and use it. (I want to do this all locally, without publishing the library, etc.)

I’ve browsed through the list of pub commands and none seems to install a package locally, so how can I use it in other projects?

For example, I just cloned this library and would like to test it locally to see if it works. How can I do that?

Solution

To use a local library, you can specify a local filepath in your pubspec, such as:

dependencies:
  transmogrify:
    path: /Users/me/transmogrify

When using a local dependency, Dart will pick up any changes automatically, so there’s no need to run a special pub command.
