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. 👉 youtu.be/X_VgMfUSid4

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. See how DCM enforces this best practice ⬇️ youtu.be/xa4zMwpXrr8
