iconify_sdk_builder 0.2.0

Code generator and build_runner builder for Iconify SDK. Generates type-safe Dart constants for icon sets defined in iconify.yaml.

iconify_sdk_builder

The code generator for the Iconify SDK. Automatically bundles icons into type-safe Dart constants for 100% offline production builds.

Overview

This package is a build_runner extension that scans your Flutter source code for IconifyIcon(...) usages. It resolves the required icon data from your local snapshots and generates a lib/icons.g.dart file.

Setup

Add the builder to your dev_dependencies:

dev_dependencies:
  iconify_sdk_builder: ^0.2.0
  build_runner: ^2.4.0

Usage

Run the build command:

dart run build_runner build

The builder will look for an iconify.yaml file in your project root to determine where your local icon snapshots are stored and where to write the generated code.

Example iconify.yaml

sets:
  - mdi:*
  - lucide:rocket
data_dir: assets/iconify
output: lib/icons.g.dart

How it Works

1. Scanning: It uses a hybrid AST + Regex scanner to find icon identifiers like 'mdi:home' in your .dart files.
2. Resolution: It searches your data_dir for the corresponding Iconify JSON snapshots.
3. Generation: It produces a type-safe Dart file containing only the icons you've actually used, ensuring zero-waste bundles.

Limitations

• Literal Strings Only: The scanner currently only detects icons passed as literal strings (e.g., IconifyIcon('mdi:home')). It cannot detect icons assigned to variables or constructed dynamically at runtime.
