DCM 💙

🚀 Announcing DCM Dashboards general availability An ultimate solution to monitor code quality for your #Flutter projects. ✅Never let important issues slip ✅Visualize technical debt ✅Track trends within your org ✅Share reports with stakeholders

Many teams want better code quality but struggle to know where to start. Techniques such as: 1⃣preview all metrics first ✅start with metrics-recommended ✏️override thresholds for your project 👩‍💻choose metrics based on your actual pain points Read more: dcm.dev/docs/guides/ch…

This lets you keep your internals private while still exposing a clean and easy-to-use constructor API. 💯 Less boilerplate ✅ Maintained encapsulation 🔁 Same behavior A small language feature, but a meaningful one for more readable code: #private-named-parameters" target="_blank" rel="nofollow noopener">github.com/dart-lang/sdk/…

Dart 3.12 lets the constructor stay aligned with the actual field names. ✅ Internally, the fields remain private. ✅ Externally, the constructor signature stays public-facing. The _ belongs to the field implementation detail, not to the public argument name.

Dart’s private named parameters, coming in Dart 3.12, are not a small syntax change. They solve a real API-design tradeoff. You often want all 3 of these at once: 1⃣Private fields 2⃣Named arguments at the call site 3⃣Thin constructors Let's see how you can write them👇

Complex conditions can impact readability. ❌ Instead of: (a && b) || (!a && c) ✅ Prefer: a ? b : c DCM’s "prefer-simpler-boolean-expressions" rule flags redundant #Dart boolean patterns and suggests more readable alternatives. Read more: dcm.dev/docs/rules/com…

Arrange, Act, Assert is the gold standard for unit testing 🧪 Why? It ensures tests are not doing "multiple rounds of arrange and act." DCM 1.32 introduced prefer-test-structure to warn when a test is not separated into these three sections. Read more: dcm.dev/docs/rules/com…

In fact, Nicholas, Team Lead at Zühlke, puts it nicely on how DCM is playing a role: “Integrate DCM from the start, before writing a single line of code. It saves enormous effort later.” Read the full case study dcm.dev/customers/zueh…

One feature stands out: memory leak detection, as Djordje, Lead Software Architect and People Lead at Zühlke says: "Memory leak detection helps a lot. I might not notice every time, DCM warns me immediately." That proved especially valuable in complex reactive flows.

🎉 A case study with Zühlke was published! They use DCM to keep complex, mission-critical #Flutter apps maintainable across healthcare, industrial engineering, and enterprise projects. 💯 Result: faster PRs, fewer regressions, and better visibility into technical debt. How?👇

🎉 We just published a case study with CarOnSale, Europe's fast-growing B2B automotive platform. They secure their Flutter mobile apps and internal libraries with DCM. 💯 The results? Smoother code reviews, automated consistency, & increased developer confidence across teams👇

#Flutter BLoC is everywhere, but hidden bugs are easy to miss: 💥 isClosed after await 🔁 same-state emits 🧠 create vs .value 🚫 public methods bypass events 🔒 sealed/immutable classes By reading BLoC source code, we see how to happen & prevent them: dcm.dev/blog/2026/03/1…

Async mistakes can quietly slow down or break your #Flutter app. This post breaks down common pitfalls: 🔄 Misused FutureOr ⚠️ Unawaited futures in initState() 🔁 Redundant async/await 🚦 Inefficient parallel calls 🧵 Confusing .then() chains 👉 dcm.dev/blog/2025/05/2…

As Roman said: "We've been using DCM since day zero... we genuinely can't imagine working without it. Any serious project should adopt it.” Read the entire case study: dcm.dev/customers/caro…

The impact was clear as manual code reviews alone simply weren't enough and standard linters lacked the depth needed for their real-world apps. 🔥 By integrating DCM analysis directly into their workflow, they stopped wasting time hunting for structural mistakes.
