strict review
A free, documented strict-lint configuration for small Dart and Flutter projects.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
strict is a free, open-source Dart package for developers who want stricter analysis in Dart and Flutter projects. It provides an analysis_options.yaml file, which teams add through a Dart development dependency and include in their project configuration. The package is a fit for solo developers and small teams seeking a documented lint baseline rather than a hosted scanning platform. Its purpose is to shape Dart's existing analysis tooling with an opinionated set of rules.
The published package details show no paid tier: strict is free to use. Setup centers on adding the package as a development dependency and referencing its analysis-options YAML file, so adoption belongs in the project's Dart configuration rather than in a separate web dashboard. Comments alongside the rules explain their rationale, giving maintainers context when deciding whether the stricter checks match their codebase. The package also documents updates tied to relevant changes in Dart's linter library, helping teams track why rules may be added or removed over time.
The main trade-off is scope. strict supplies configuration for Dart analysis and Flutter analysis, but it is not a hosted static-analysis service and does not provide security analysis. That makes it appropriate for projects already using Dart's analyzer and looking for a stricter, maintainable rule set. Teams needing centralized scanning, a wider language footprint, or security-focused analysis should choose a broader analysis product instead. Developers who prefer explicit, commented rules and a lightweight dependency will find the package's narrow focus easier to evaluate than a full service stack.
strict pros and cons
- Where it wins
- Free, open-source configuration for Dart and Flutter analysis
- Rule comments explain the rationale behind individual lints
- Tracks relevant additions and removals in Dart's linter rules
- Where it doesn't
- Configuration package rather than a hosted static-analysis service
- Focused on Dart and Flutter projects, not security analysis
- Opinionated rules may not fit teams wanting a broader analysis product
