Usage #
In class you want to write toString() method:

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

/// cat.dart
import 'package:to_string/to_string.dart';

part 'cat.g.dart';

@ToString()
class Cat {
Cat(this.color, this.weight);

String color;
double weight;

@override
String toString() {
// [_$CatToString] is generated at `cat.g.dart`,
// and it returns likes "Cat{color: white, weight: 1.2}"
return _$CatToString(this);
}
}

By default, getter, static field, and private field will not be shown in
toString. But you can use ToString to make them show.
/// cat.dart
import 'package:to_string/to_string.dart';

part 'cat.g.dart';

@ToString()
class Cat {

@ToString()
static int leg = 4;

Cat(this.color, this.weight, this.wings);

String color;
double weight;
String wings;

String _heart = "warm";

@ToString()
bool get hasWings => wings != null;

@override
String toString() {
// [_$CatToString] is generated at `cat.g.dart`,
// and it returns likes this:
// "Cat{leg: Cat.leg, color: white, weight: 1.2, wings: null, _heart: warm, hasWings: false}"
return _$CatToString(this);
}
}

Supper Class And Mixin #
If you annotate ToString() to the class`s supper class or mixin, their
field (public field and other field with ToString()) will be include
in the base class method toString.
/// cat.dart
@ToString()
class Animal {
bool needOxygen = true;
}

@ToString()
class Rocket {
bool canFly = true;
}

@ToString()
class Cat extends Animal with Rocket{

String name;

@override
String toString() {
// [_$CatToString] is generated at `cat.g.dart`,
// and it returns likes this:
// "Cat{needOxygen: true, canFly: true, name: kitty}"
return _$CatToString(this);
}
}

Pretty Print Supports #
Pretty print supports nested class indent!
Cat{
classify: Animal,
color: red,
weight: 12.0,
wings: has,
ball: Ball{ <= nested
color: red,
},
}

There are two ways you can enable pretty print:
Use ToString() annotation:
ToString(
prettyPrint: true,

// default to " "
indent: " ",
)
/// class Cat {...
copied to clipboard
Create a file build.yaml with code and enable all class pretty print:
targets:
$default:
builders:
to_string_generator|to_string:
options:
prettyPrint: true
indent: " "

Lastly, we use build_runner!
