Automatically generating `copyWith` extensions code for classes with `@CopyWith()` annotation.

Pub Package

Provides Dart Build System builder for generating copyWith extensions for classes annotated with copy_with_extension.

Usage #

In your pubspec.yaml file:

  • Add to dependencies section copy_with_extension: ">=1.0.0 <2.0.0"
  • Add to dev_dependencies section copy_with_extension_gen: ">=1.0.0 <2.0.0"
  • Add to dev_dependencies section build_runner: ">=1.0.0 <2.0.0"
  • Set environment to at least Dart 2.7.0 version like so: ">=2.7.0 <3.0.0"

Your pubspec.yaml should look like so:

name: project_name
description: project description
version: 1.0.0

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  ...
  copy_with_extension: ">=1.0.0 <2.0.0"
  
dev_dependencies:
  ...
  build_runner: ">=1.0.0 <2.0.0"
  copy_with_extension_gen: ">=1.0.0 <2.0.0"

Annotate your class with CopyWith annotation:

import 'package:copy_with_extension/copy_with_extension.dart';

part 'basic_class.g.dart';

@CopyWith()
class BasicClass {
  final String id;

  BasicClass({this.id});
}

Make sure that you set the part file as in the example above part 'your_file_name.g.dart';.

The extension will be generated:

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'basic_class.dart';

// **************************************************************************
// CopyWithGenerator
// **************************************************************************

extension CopyWithExtension on BasicClass {
  BasicClass copyWith({
    String id,
  }) {
    return BasicClass(
      id: id ?? this.id,
    );
  }
}
