copy_with_e_generator 1.0.11
copy_with_e_generator: ^1.0.11 copied to clipboard

Creates copyWith extension methods for each annotated class and works with abstract too.

copy_with_e #

You want to copy your object and change individual property values? #

var bob = Person(age: 5, name: "bob");

bob.cwPerson(age: 6, name: "bobby");

... then use copy_with_e #

copy_with_e is dart nullsafety compatible (and works on subclasses too unlike most implementions, see below)

Just put the CopyWithE annotation on the class
@CopyWithE()
class Person {
  final int age;
  final String name;

  Person({this.age, this.name});
}
add the dependencies
dependencies:
  copy_with_e_annotation: ^1.0.2-nullsafety2

dev_dependencies:
  copy_with_e_generator: ^1.0.2-nullsafety2
and build the generated code
pub run build_runner build
You can also copy by interface type
var bob = Person(age: 5, name: "bob");
var rob = Employee(age: 9, name: "rob");
var hasAges = <HasAge>[bob, rob];

//add a year to all employees & people
hasAges.map((x) => x.cwHasAge(age: 3 + 1));
...if a class implementing an interface is in a different file you need to tell CopyWithE annotation about those classes (for classes in the same file it is automatic)
@CopyWithE([Person, Employee])
abstract class HasAge {
  int get age;
}
