+# Icon Regeneration Guide
+
+This document describes how to regenerate app icons from the source icon files.
+
+## Source Icons
+
+- **Primary source**: `res/icon.png` (2048x2048 PNG) - Used for iOS and Android
+- **SVG source**: `flutter/assets/icon.svg` - Vector format, can be used to generate any resolution
+- **macOS source**: `res/mac-icon.png` - Specific macOS variant
+
+## Prerequisites
+
+Install required tools:
+```bash
+sudo apt-get install librsvg2-bin imagemagick
+```
+
+## Regenerating iOS Icons
+
+### Method 1: Using ImageMagick (Manual)
+
+```bash
+#!/bin/bash
+SOURCE_ICON="res/icon.png"
+OUTPUT_DIR="flutter/ios/Runner/Assets.xcassets/AppIcon.appiconset"

+
+### Method 2: Using flutter_launcher_icons (Automated)
+
+```bash
+cd flutter
+flutter pub run flutter_launcher_icons
+```
+
+This uses the configuration in `flutter/pubspec.yaml`:
+```yaml
+flutter_icons:
+  image_path: "../res/icon.png"
+  remove_alpha_ios: true
+  ios: true
+  android: true
+```
+
+## Regenerating Android Icons
+
+```bash
+SOURCE_ICON="res/icon.png"
+BASE_DIR="flutter/android/app/src/main/res"
+
+convert "$SOURCE_ICON" -resize 48x48 "$BASE_DIR/mipmap-mdpi/ic_launcher.png"
+convert "$SOURCE_ICON" -resize 72x72 "$BASE_DIR/mipmap-hdpi/ic_launcher.png"
+convert "$SOURCE_ICON" -resize 96x96 "$BASE_DIR/mipmap-xhdpi/ic_launcher.png"
+convert "$SOURCE_ICON" -resize 144x144 "$BASE_DIR/mipmap-xxhdpi/ic_launcher.png"
+convert "$SOURCE_ICON" -resize 192x192 "$BASE_DIR/mipmap-xxxhdpi/ic_launcher.png"
+```
+
+Or use `flutter_launcher_icons` as shown above.
+
+## Updating Source Icon from SVG
+
+If you need to regenerate the source PNG from the SVG at a different resolution:
+
+```bash
+# Generate 2048x2048 PNG from SVG
+rsvg-convert -w 2048 -h 2048 flutter/assets/icon.svg -o res/icon.png
+
+# Or for even higher resolution (4096x4096)
+rsvg-convert -w 4096 -h 4096 flutter/assets/icon.svg -o res/icon.png
+```
+
+## iOS Icon Requirements
+
+- All iOS icons must have alpha channel removed (opaque)
+- White background is applied to maintain appearance
+- Icons are automatically rounded by iOS system
+- Retina displays require @2x and @3x variants
+
+## Icon Sizes
+
+### iOS
+- 20pt (20x20, 40x40, 60x60)
+- 29pt (29x29, 58x58, 87x87)
+- 40pt (40x40, 80x80, 120x120)
+- 60pt (120x120, 180x180)
+- 76pt (76x76, 152x152) - iPad
+- 83.5pt (167x167) - iPad Pro
+- 1024x1024 - App Store
+
+### Android
+- mdpi: 48x48
+- hdpi: 72x72
+- xhdpi: 96x96
+- xxhdpi: 144x144
+- xxxhdpi: 192x192
+
+## Quality Tips
+
+1. Always start from the highest resolution source available (SVG preferred)
+2. Use at least 2048x2048 PNG as intermediate source
+3. Let ImageMagick/flutter_launcher_icons handle downscaling
+4. Never upscale low-resolution images - regenerate from vector source
+5. Test on actual devices with Retina displays to verify quality
