🧐 The Problem

As Flutter apps grow, developers often leave behind unused images, fonts, and SVGs. These "ghost assets" bloat your final APK/IPA size, hurting your app's download conversion rate.

Asset Hound automatically scans your pubspec.yaml, searches your file system, and analyzes your Dart code to find exactly which assets are wasting space—allowing you to safely delete them and generate beautiful savings reports.

---

🚀 Quick Start

Asset Hound is designed to be run globally from your terminal. Activate it once:

dart pub global activate asset_hound

Navigate to your Flutter project and let the hound off the leash:

dart run asset_hound scan

---

🛠️ Usage & Commands

Run the scan command to analyze your project. You can customize the scan using various flags:

Flag	Abbreviation	Description
--report=<format>	-r	Generates a savings report. Supported formats: html, json.
--auto-fix	-f	(Caution) Automatically deletes the unused assets found during the scan.
--dry-run	-d	Simulates an auto-fix deletion without actually harming any files.
--verbose	-v	Prints detailed logging information. Great for debugging.
--protect=<list>	-p	Comma-separated list of native config packages to protect from deletion.

Example: Generate a beautiful HTML dashboard of your unused assets:

dart run asset_hound scan --report=html

---

⚙️ Configuration (Optional)

Asset Hound is smart enough to handle dynamically generated paths (like assets/icons/icon_$index.png) using fuzzy directory matching. However, if you need to explicitly ignore certain directories, you can configure it directly in your pubspec.yaml.

Add an asset_hound block to the bottom of your file:

# pubspec.yaml

asset_hound:
  ignore:
    # Ignore all videos
    - assets/videos/**
    # Ignore a specific file
    - assets/images/do_not_delete.png

Native Package Protection

By default, Asset Hound automatically protects native assets configured by popular packages (like flutter_native_splash and flutter_launcher_icons). If you use custom packages, you can protect them via the CLI:

dart run asset_hound scan --protect=my_custom_splash,other_icons
