icon_data_generator

A Dart code generator package to produce Flutter Material Icon mappings using build_runner. This tool enables automated generation of icon code point to name mappings, making it ideal for Flutter applications that require icon metadata at runtime or during development.

---

✨ Features

• 🔧 Automatically extracts IconData mappings from Flutter's icons.dart
• ⇁ Generates code for bidirectional mapping between icon names and code points
• 🔌 Seamless integration with build_runner workflows

---

🚀 Getting Started

📦 Installation

Add the following to your pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter

dev_dependencies:
  icon_data_generator:
    git:
      url: https://github.com/your-org/icon_data_generator.git
  build_runner: latest_version

---

⚙️ Usage

Run the code generation command:

flutter pub run build_runner build

This will generate:

• lib/icon_maps/material_icons_mapper.g.dart
• lib/icon_maps/material_icon_data_map.g.dart

These files contain:

• A Map<int, String> for code point to icon name resolution
• A Map<String, int> for icon name to code point resolution

---

🛠️ Output Example

// material_icons_mapper.g.dart

const Map<int, String> iconCodePointToName = {
  57344: 'ten_k',
  59136: 'ten_k_sharp',
  62687: 'ten_k_rounded',
  60914: 'ten_k_outlined',
  // ... more icons
};

const Map<String, int> iconNameToCodePoint = {
  'ten_k': 57344,
  'ten_k_sharp': 59136,
  'ten_k_rounded': 62687,
  'ten_k_outlined': 60914,
  // ... more icons
};

---

🧹 Use Case

Ideal for:

• Icon pickers
• Runtime icon inspection
• Custom UI rendering based on icon metadata
