A command line tool for sorting Dart members in a .dart file.

Mimics the behavior of the official 'Sort Members in Dart File' IDE helper provided by the Dart LSP server (/src/services/correction/sort_members.dart) as of October 2026. There is no guarantee that this tool will always follow the official behavior, but that is how we started.

Disclaimer: Almost all of the code in this package is built by LLMs. This project is both simple enough and uncreative enough that I have no trouble outsourcing the work to a tool.

Installation

dart pub global activate sort_dart_members

Usage

In order to simply check if a file is already sorted:

sortdart path/to/file.dart --check

This only outputs whether or not that file is already sorted, and also expresses the same result with an exit code (0 = sorted, 1 = not).

If you want to see what the file will look like:

sortdart path/to/file.dart

This will output the sorted file to stdout.

If you want to apply the sorting in place, use --overwrite (-w):

sortdart --overwrite path/to/file.dart

Other options

This is the output of sortdart --help as of October 2026.

sortdart --help
