many_lints review
A free, open-source Dart analysis plugin with configurable rules and quick fixes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
many_lints is a free, open-source Dart analysis server plugin for developers working on Dart and Flutter projects. Its rule coverage includes widget practices, state management, async safety, code quality, and architecture, making it relevant to teams that want to shape static analysis around their coding conventions. Configuration lives in analysis_options.yaml or a standalone many_lints.yaml file, so it fits projects that already manage analysis settings in configuration files.
Rule selection is the main strength and the main setup consideration. The package provides 261 lint rules, 106 quick fixes, and code assists, including refactorings for Dart and fpdart code. Teams can start from presets, enable rules individually, apply overrides, configure per-rule include and exclude globs, and set diagnostic severity. That range supports tailored policies, but all rules are disabled by default, so a team needs to decide which checks to activate rather than expecting a preset baseline to run automatically. This makes it a better fit for developers prepared to curate their lint configuration than for those seeking an immediately opinionated default.
Its ecosystem fit centers on Dart's analysis server plugin system and dart analyze; IDEs connect through that system, though named IDE integrations are not specified. The package is installed and configured within a project, making it a self-hosted option rather than a separate hosted analysis service. The package is MIT-licensed and has a free plan, with no tiered pricing distinction to weigh. Choose many_lints if configurable Dart and Flutter linting, quick fixes, and assists matter more than a turnkey setup. Teams needing explicit IDE-specific compatibility or analysis beyond Dart and Flutter should consider a broader alternative.
