✨ Tip: Avoid unnecessary collections in your Dart code! Why? - Wrapping a single element in a collection is often redundant. - It makes your code less efficient and harder to read. - Use value directly instead of [value] where possible. ✅ Examples: - await Future.wait([future]) → await future - _array.addAll([value]) → _array.add(value) Learn more: https://lnkd.in/eD3WW67j

✨ Pro Tip: Be cautious when overriding a getter that’s already passed to super! ⚠️ Why? - It can cause unintended behavior. - The overridden getter may conflict with the inherited field. - Instead of overriding, reference the super field or remove the getter. 💡 DCM automatically detects and helps fix these cases for more reliable code.

✨ Pro Tip: Organize your Flutter projects by following the "one widget per file" principle! DCM ensures that each widget has its own file, promoting: - Single responsibility for better maintainability - Better structured codebases - Easier collaboration within teams This rule has ⚙️ config option: - Ignore private widgets (ignore-private-widgets: true) for flexibility.
