copy_with_annotation

This package generates a copyWith method using build_runner and json_serializable

Installation

Add dependencies in your pubspec.yaml:

dependencies:
  copy_with_annotation:

dev_dependencies:
  copy_with:
  build_runner:

Usage

In class you want to write toString() method:

• Annotate the class with ToString()
• Override the toString method.

import 'package:json_annotation/json_annotation.dart';
import 'package:copy_with_annotation/copy_with_annotation.dart';

part 'person.g.dart';

@CopyWith()
@JsonSerializable()
class Person {
  final String firstName;
  final String lastName;
  final DateTime dateOfBirth;

  Person({
    this.firstName,
    this.lastName,
    this.dateOfBirth,
  });
}

Building creates the corresponding part person.g.dart:

part of 'person.dart';

extension $PersonCopyWith on Person {
  Person copyWith({
    String firstName,
    String lastName,
    DateTime dateOfBirth,
  }) {
    return Person(
        firstName: firstName ?? this.firstName,
        lastName: lastName ?? this.lastName,
        dateOfBirth: dateOfBirth ?? this.dateOfBirth,
    );
  }
}
