🚀 Flutter Find Unused Resources

Shrink your app. Ship faster. Stay clean.

The all-in-one VS Code extension for Flutter developers to eliminate dead code and analyze build size — without leaving your editor.

⚡ See it in Action!

✨ Why Flutter Find Unused Resources?

Every Flutter project accumulates technical debt over time — forgotten assets, abandoned classes, deprecated methods, and unused packages quietly bloat your app's size and slow down your team. Flutter Find Unused Resources gives you X-ray vision into your codebase and your builds, so you can cut the fat and deliver a leaner, faster app to your users.

⚡ No more guessing. No more manual searches. Just clean, optimized Flutter code.

🎯 Features

🧹 Source Code Cleanup

Automatically detect dead code lurking in your Flutter project — all from a dedicated panel inside VS Code.

• 🔍 Unused Classes — Instantly find classes defined but never referenced anywhere in your project.
• 🔧 Unused Methods — Surface methods that are declared but never called.
• 📦 Unused Packages — Identify pubspec.yaml dependencies you're importing but not actually using.
• 🖼️ Unused Assets — Spot image, font, and file assets declared in pubspec.yaml that no code ever loads.
• 🖱️ Click-to-Navigate — Click any detected issue in the tree view to instantly jump to the exact file and line — no manual searching required.
• ⚡ Powered by Dart CLI — Analysis runs via a robust background Dart CLI tool, delivering accurate, project-wide results without slowing down your editor.

📊 Build Size Analysis

Stop wondering what's eating your app's megabytes. Analyze your existing APK or IPA file in seconds — no rebuild needed.

• 📂 Zero Rebuild Required — Point the extension at an already-built .apk or .ipa file and get instant insights.
• 🎯 Smart File Picker — The built-in file picker filters exclusively for .apk and .ipa extensions so you always load the right file.
• 🥧 Animated Pie Chart — A gorgeous, Chart.js-powered interactive pie chart breaks down your app's composition by category:
  • 🎨 Assets
  • ⚙️ Native Code
  • 🎯 Dart Code
  • ...and more
• 🏆 Top 5 Heaviest Files — A detailed table highlights the five largest contributors to your build size, so you know exactly where to focus your optimization efforts.
• 🖥️ Beautiful Dashboard — Results are presented in a sleek Webview Panel dashboard directly inside VS Code — no browser, no external tools.
