mix_generator

A package that provides code generation for Spec and Dto classes in the Mix package. It simplifies the creation of Spec and Dto classes by automatically generating the necessary code based on annotated classes.

Installation

To use Mix Generator, add the following dependencies to your pubspec.yaml file:

flutter pub add mix
flutter pub add mix_annotations
flutter pub add:dev mix_generator

pubspec.yaml

dependencies:
  mix: ^0.0.0
  mix_annotations: ^0.0.0

dev_dependencies:
  build_runner: ^0.0.0
  mix_generator: ^0.0.0

Usage

MixableSpec

The @MixableSpec() annotation generates code for a mixable class. Here's an example:

import 'package:mix/mix.dart';
import 'package:mix_annotations/mix_annotations.dart';

part 'my_spec.g.dart';

@MixableSpec()
final class MySpec extends Spec<MySpec> with _$MySpec {
  final String? name;
  final int? age;

  const MySpec({this.name, this.age});
}

MixableDto

The @MixableDto() annotation generates code for a mixable Dto. Here's an example:

Options

  • mergeLists - Defaults to true, merges lists in place.
  • generateUtility - Defaults to true, generates a utility class.
  • generateValueExtension - Defaults to true, generates a value extension to convert Value to Dto with a toDto() extension.
import 'package:mix/mix.dart';
import 'package:mix_annotations/mix_annotations.dart';

part 'value_dto.g.dart';

@MixableDto()
final class ValueDto<Value> extends Dto<Value> with _$MyDto {
  final String? name;
  final int? age;

  const ValueDto({this.name, this.age});
}

MixableProperty

The @MixableProperty() annotation specifies a mixable property for code generation. Here's an example:

import 'package:mix_generator/mix_generator.dart';

@MixableProperty(
  dto: MixableFieldDto(type: BoxConstraintsDto),
  utilities: [
    MixableUtility(
      properties: [
        (path: 'minWidth', alias: 'minWidth'),
        (path: 'maxWidth', alias: 'maxWidth'),
      ],
    ),
  ],
)
final BoxConstraints? constraints;

MixableUtility

The @MixableUtility() annotation specifies a mixable utility for code generation. Here's an example:

import 'package:mix_generator/mix_generator.dart';

@MixableProperty(
  utilities: MixableUtility(
    type: BoxDecoration,
    properties: [
      (path: 'color', alias: 'color'),
      (path: 'border', alias: 'border'),
      (path: 'borderRadius', alias: 'borderRadius'),
    ],
  ),
)
final Decoration? decoration;

Code Generation

To generate the code for your mixable classes and Dtos, run the following command:

flutter pub run build_runner build
