What is the use of extending model class with Equatable in flutter

Question

class PushOtpResponse extends Equatable {
  final bool? isSuccess;
  final String? message;

  const PushOtpResponse({this.isSuccess, this.message});

  factory PushOtpResponse.fromJson(Map<String, dynamic> json) {
    return PushOtpResponse(
      isSuccess: json['isSuccess'] as bool?,
      message: json['message'] as String?,
    );
  }

  Map<String, dynamic> toJson() => {
        'isSuccess': isSuccess,
        'message': message,
      };

  @override
  bool get stringify => true;

  @override
  List<Object?> get props => [isSuccess, message];
}

The model class given above is created using json to dart extension of VSCode. There is an option for extending the class with equatable. So, is there any use in extending a model class with equatable and is there any help 'stringify' can do here.

Answer 1

I'd suggest you to just read the documentation of Equatable. Equatable is not a default class of flutter, and whoever added that code to your project must have deliberately included the package
