LowFile-scopeDart Plug & play

Remove unused imports

Delete imports that are not referenced by the compilation unit.

Why this matters

Reduces noise, compile time, and accidental side effects.

Side-by-side examples engineers can pattern-match during review.

Avoid

import 'dart:io'; // not used

Prefer

// removed unused import; keep only what is referenced

Bad

import 'package:x/y.dart'; // unused

Good

// no unused imports

From the same buckets as this rule.

Critical
Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
