leancode_lint review
A configurable, open-source analyzer package for Dart, Flutter, Bloc, and Cubit conventions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
leancode_lint is an open-source package of analyzer lint rules for Dart and Flutter projects. It is aimed at teams that want project-level coding conventions covering Dart language patterns, class structure, Flutter widget usage, BuildContext practices, and Bloc or Cubit naming and usage. The package fits solo developers through enterprise teams, with particular relevance for Flutter codebases organized around Bloc or Cubit conventions. It is published by LeanCode on pub.dev under the Apache-2.0 license.
Adoption centers on configuration rather than a separate hosted service. Developers add leancode_lint as a development dependency, include its analysis options, and enable its analyzer plugin. The package ships a default analyzer plugin configuration while also supporting custom plugin configuration. Individual lint rules can be enabled or disabled in analysis_options.yaml, allowing teams to adjust the rule set to their conventions. IDE code assists are provided, and the documentation gives VS Code as an example of IDE support.
Its breadth is concentrated on Dart and Flutter development rather than broader application security or multi-language analysis. The included rules address Flutter widget patterns, Dart classes and language constructs, and Bloc or Cubit usage, making the package a focused choice for teams standardizing those practices. Teams seeking security analysis, AI-assisted capabilities, or conventions outside this ecosystem should select a different analyzer or complement it with other tooling. Teams wanting an open-source, configurable lint package for Dart and Flutter should consider leancode_lint.
