zmodel_to_dart 0.1.0

A Dart builder to generate DTO classes from ZModel schema files

zmodel_to_dart

A Dart builder that generates DTO classes from .zmodel files.

Features

• Parses model, abstract model, and enum declarations
• Generates DTO classes with fromJson and toJson
• Supports inherited fields from extends
• Handles scalar values, enums, bytes, arrays, and nested model references

Usage

1. Add to your pubspec.yaml:

dev_dependencies:
    zmodel_to_dart: ^0.1.0
    build_runner: ^2.7.0

2. Create a .zmodel file:

enum role {
    admin
    reader
}

model user {
    id String @id
    name String
    role role
}

3. Optionally create zmodel_to_dart.yaml in the package root:

input_globs:
  - schema/*.zmodel
output_suffix: .zmodel.dart
output_dir: lib/data/dtos
banner: // AUTO GENERATED FILE, DO NOT EDIT

4. Run:

dart run build_runner build

This generates a sibling file like user.zmodel.dart.

The builder reads zmodel_to_dart.yaml automatically. build_runner still needs a minimal build.yaml entry to enable the builder, but input filtering and output naming can live in zmodel_to_dart.yaml.

Suggestions

• Keep your .zmodel files close to the modules that consume the generated DTOs.
• Use the builder when you want generated files to stay synchronized automatically.

To run standalone

Usage: dart run zmodel_to_dart <path_to_zmodel_file> [output_dir]

If you omit the CLI arguments, zmodel_to_dart will try to resolve a single source file from input_globs in zmodel_to_dart.yaml and will use output_dir from that file.
