Dart Guide

The Dart implementation uses an explicit AsunSchema interface and factory-based typed decode helpers.

Minimum Version

• Dart 3.0+

Implementation Model

• User types implement AsunSchema.
• Text decode can return a field bag or use decodeWith / decodeListWith for typed values.
• Binary decode requires field names, field types, and a factory function.

Current Support

• encode, encodeTyped
• encodePretty, encodePrettyTyped
• decode, decodeWith, decodeListWith
• encodeBinary, decodeBinaryWith, decodeBinaryListWith

Example

class User implements AsunSchema {
  final int id;
  final String name;
  final bool active;

  User({required this.id, required this.name, required this.active});

  @override List<String> get fieldNames => ['id', 'name', 'active'];
  @override List<String?> get fieldTypes => ['int', 'str', 'bool'];
  @override List<dynamic> get fieldValues => [id, name, active];
}

Notes

• encodeTyped is the better default when you want round-trip type preservation.
• Binary decode is schema-driven and therefore needs explicit field metadata plus a factory.
• Keyed collections should be modeled as entry-list arrays.
