DCM improved BoursoBank's Flutter runtime safety, catching errors early before production. Applied to 60+ packages, DCM gave developers confidence that sensitive payment and authentication flows are protected.
Read the entire case study: dcm.dev/customers/bo...
Using DCM, they enabled:
🔸 Pre-commit hooks & strict CI checks
🔸 ~20 targeted, safety-first linting rules enabled
🔸 Automated elimination of unsafe APIs & provider lookup errors
🔸 Sonar-compatible reporting for internal governance
👇
Scaling a 60+ package monorepo with developers transitioning from web to Dart while maintaining strict banking compliance wasn’t easy!
Imagine needs for strict CI checks, auto-detection, and automation to eliminate unsafe APIs with Sonar-compatible reporting!
👇
We just published a case study with BoursoBank, France’s largest online bank!
They secure mission-critical #Flutter mobile & web apps with DCM.
💯 The results? maintainable architecture, & zero crashes in payment & authentication flows for 70+ engineers
Here's how they do it 👇
Ever discovered a Flutter widget and thought, “Why didn’t I see this sooner?” 🤔
We’ve uncovered 10 under-the-radar widgets that even seasoned devs almost never use! 👇

What widget surprised you the most?
Are silent bugs hiding in your #Flutter Provider code?
You might be missing:
💥 .value trap
🚫 .dispose gap
👀 .read vs .watch
✋ .selector logic
We explored the Provider's source code to uncover common architecture mistakes: dcm.dev/blog/2026/03...
Once you have multiple #Flutter projects, it's often required to manage different DCM versions.
Our new guide covers:
🔄 Fast version switching
💻 Helper scripts (Zsh, Bash, Fish, PS)
💙 FVM support
🤝 Team consistency with dcm_global.yaml

🤷♂️ Assigning values that never get used?
Enable the "avoid-unused-assignment" rule that warns when an assignment is not used in the following statements.

We recently published a case study with Betterment where the team adopted DCM into their workflow, which helped them to:
- Cut feedback cycles from minutes to seconds
- Focus on architecture review rather than styling
- Ship faster & safer

🧠 Ever found a #Dart or #Flutter function that completely changed how you think about coding?
We’ve rounded up 10 underrated functions that can simplify code, reduce boilerplate, and teach you something new about the language itself.
📖 dcm.dev/blog/2025/02...
Dart 3.10's dot shorthands are game changers for #Flutter code:
✅ shorter enums, less boilerplate, and sharper syntax.
⚠️ But beware the hidden complexities!

🖼️ Wrapping a #Flutter Image widget with an Opacity widget?
That’s inefficient. The DCM rule "avoid-incorrect-image-opacity" warns you to use the "opacity" parameter directly instead.

🤯 8 Flutter widgets you’re probably overlooking and why they matter.
In this article, we will show practical usage + their implementation source code to learn more from!
Which one surprised you? 👉 dcm.dev/blog/2025/10...
Ever written a function that always returns the same value (like "true")? 🤔
It usually means the logic isn’t doing what you think.
The "function-always-returns-same-value" rule catches these bugs before they spread! 👉 dcm.dev/docs/rules/c...
Overriding fields from a super constructor with a getter? 🤔 That can break your code or lead to unexpected results!
The "avoid-suspicious-super-overrides" rule helps you quickly spot and fix such issues.

AI is speeding up coding but also technical debt ⚡️
In our new post we have brought to you how #Dart & #Flutter devs can use Dart & Flutter and DCM MCP servers to:
- Automate cleanup loops
- Enforce lints & metrics
- Keep AI-generated code maintainable
Read here: dcm.dev/blog/2025/08...
If your #Flutter widget tree has a matching sequence of "Align", "Padding", "ClipPath", and others, it can often be replaced with a single "Container" widget.
Use the "prefer-container" rule to simplify the layout dcm.dev/docs/rules/f...
📦 One widget per file = easier-to-navigate, easier-to-maintain #Flutter code.

✅ It often hides unfinished work or dead logic
✅ Adds noise and confusion for other devs
✅ Git handles history anyway
