🤔 Most teams can tell when a Flutter method feels too complex. The problem is that “too complex” is subjective.

Read "Cyclomatic Complexity, #Flutter Guide" & learn how to shield your code and to refactor it down and protect your team now & later!

✨ Still doing manual null checks in your collection literals?

When it comes to #Flutter widget code, there are different expectation compared to plain domain logic.

That’s why our guide separates widget metrics from non-widget metrics, so UI, services, and domain logic are measured differently: https://t.co/aCx6ErmZ0T

[DCM 💙 @DCMAnalyzer]

Advanced metrics configuration in DCM is where metrics become practical.

You’re not limited to one global threshold. You can tune metrics for legacy code, new features, widget-heavy UI, critical paths, and even dashboards-only tracking.

In this guide, learn how you can do it 👇

[DCM 💙 @DCMAnalyzer]

Don’t disable a metric if the default threshold does not really work, instead:

✅ Use entries for stricter new code
✅ Give legacy folders a temporary threshold

That way, new code improves without blocking every release because of old code.

🚀 Quality code tip: Use the variable you already created.

It's easy to miss, but the "use-existing-variable" rule catches repeated expressions when a variable already exists.

🪧 Less code
🔁 Less duplication
✅ Fewer inconsistencies

🎉 A case study with Appinio was published!

Appinio is a fast-growing global market research platform. Their mobile team delivers production-grade Flutter apps and uses DCM to maintain high development velocity without compromising long-term maintainability.

How? 👇

[DCM 💙 @DCMAnalyzer]

The DCM baseline keeps the team on top of legacy issues, separate from new code.

Real-time IDE feedback enforces consistent structure and patterns, and GitHub Actions automation ensures that no PR is merged without passing DCM checks.

Heads up, there’s a code freeze a-comin! 🥶💙

To move Material and Cupertino downstream to the stable branch in flutter/packages, we’ll be freezing these libraries with our next release cut-off on April 7

A small #Flutter lint that can prevent confusing layout issues: avoid-flexible-outside-flex.

This rule warns when Flexible is used outside a Flex widget, such as Row, Column, or Flex, helping keep widget tree layouts working correctly.
