Typed functional composition in Dart.


C(initial value).x(first function).x(second function).execute();

Todo / might do later

  • output a function
  • define just a function
  • Cannot implement the >> operator because operator generics are not possible in Dart at the moment

This is just a playful thing, nothing serious!


  • Update readme with todos


  • Update readme and fix an import naming bug

Health issues and suggestions

Document public APIs (-10 points)

13 out of 13 API elements (library, class, field or method) have no adequate dartdoc content. Good documentation improves code readability and discoverability through search.

Format lib/composefn.dart.

Run dartfmt to format lib/composefn.dart.

Maintenance suggestions

The description is too short. (-20 points)

Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

Maintain an example. (-10 points)

Create a short demo in the example/ directory to show how to use this package. Common file name patterns include: main.dart, example.dart or you could also use fn_compose.dart.

Package is pre-v0.1 release. (-10 points)

While there is nothing inherently wrong with versions of 0.0.*, it usually means that the author is still experimenting with the general direction of the API.
