Schemantic

Schemantic is a general-purpose Dart library used for defining strongly typed data classes that automatically bind to reusable runtime JSON schemas. It is standard for the genkit-dart framework but works independently as well.

Core Concepts

Always use schemantic when strongly typed JSON parsing or programmatic schema validation is required.

• Annotate your abstract classes with @Schema().
• Use the $ prefix for abstract schema class names (e.g., abstract class $User).
• Always run dart run build_runner build to generate the .g.dart schema files.

Basic Usage

1. Defining a schema:

import 'package:schemantic/schemantic.dart';
