dson's Issues

First example doesn't compile

I had to use @Property("renamed") and change the type of the otherName to String from bool. Also, the double dot notation did not work in the creation and assignment in the EntityClass constructor.

Unable to serialize object to json

Hi,
I'm trying to serialize the object EVendor below into json, but I get an exception "the getter isEnum was called on null". Follow the object I'm trying to serialize below:

part 'package:ucount_flutter/entities/evendor.g.dart';

@serializable
class EVendor  extends _$EVendorSerializable{
  int id;
  int userID;
  int categoryID;
  String name;
  String description;
  DateTime dateInserted;

  EVendor({this.name, this.id});

  noSuchMethod(Invocation invocation) {
    super.noSuchMethod(invocation);
  }
}

There seems to be no support for enums, which would be nice. Now I get the error

Calling toMap() on an object with null fields throws an error

dson version: 0.15.5

dson_core version: 0.15.4

Minimal example to reproduce bug:

/* test.dart */
import 'package:dson/dson.dart';

part 'test.g.dart';

main(List<String> args) {
  toMap(new SimpleTest());
}

@serializable
class SimpleTest {
  String x;
  SimpleTest() {
    x = null;
  }
}

After build_runner build, run the script and the following error was thrown:

Unhandled exception:
NoSuchMethodError: The getter 'isEnum' was called on null.
Receiver: null
Tried calling: isEnum
#0      Object.noSuchMethod (dart:core/runtime/lib/object_patch.dart:50:5)

#6      _RawReceivePortImpl._handleMessage (dart:isolate/runtime/lib/isolate_patch.dart:171:12)

The error appears to be from this line in dson_core, so I went to see the code. It seems that this instance variable somehow passed the primitive type check at line 11 (which in theory should block this null value):

bool isPrimitive(value) => value is String || value is num || value is bool || value == null;

Then this null value got to _serializeObject() function, passed to the reflect() function in built_mirrors_core and returned as null instead of a ClassMirror object.

I have little idea how this should be fixed though...

update: fixed format error

Rename methods from serialize and deserialize to toJson and fromJson

What do you think on rename:

serialize to toJson
deserialize to fromJson
deserializeList to fromJsonList
objectToSerializable to toMap
map to fromMap
mapList to fromMapList

Ignore unknown fields

Hi,
Currently, when I don't map a field I'm getting FieldNotFoundException.
furthermore, if I will extend my API response and add new fields to it, the fromJson will throw an exception (FieldNotFoundException) and it will not parse it to the relevant entity,
In addition, if I don't want to map all the fields in the entity the same result will happen.

There is a way maybe by an annotation that I can add on the Entity that will disable the throwing of the exception, the exclude and the ignore didn't help me.

Thanks

Exception when deserializing simple json object.

I've got exception when deserializing simple json:

Exception: Uncaught Error: type 'List<Object>' is not a subtype of type 'List<InstanceMirror>' of 'ams'.
Stack Trace:
#0      GetValueOfAnnotation._fromAnnotations (package:drails_commons/src/scanners.dart:16:43)

#4      _fillObject (package:dson/src/deserializer.dart:122:68)
#5      fromJson (package:dson/src/deserializer.dart:23:3)

The argument of GetValueOfAnnotation._fromAnnotations() should probably be List<Object> not List<InstanceMirror>.

A 'hashCode' Problem

If the property id is not present in the object, How do I avoid getting the hashcode value?

Make it work with reflectable>=0.3.1

We have to make it work somehow because polymer-dart 1.0.0-rc.2 now depends from it

class with getter field throws FieldNotFoundException when using fromMap/fromJson

I read the generated code, and the SerializableMap's code
please allow me using the easiest way

fromMap method will try to assign getter with value, because it uses class mirror fields as the list, and class mirror fields contains getter field.
[]= method will throw FieldNotFoundException when unsupported key is given
So, fromMap will throw FieldNotFoundException, when getter field exists.

Does dson support mulitiple Generic？

how suppout mulitiple Generic look like:List<Person<Person3, Person4>>,
i give the type :
$mkType = [
() => List<Person<Person3, Person4>>(),
[
() => Person<Person3, Person4>(),
[
{
$key_Person_1: [() => Person3(), Person3]
},
{
$key_Person_2: [() => Person4(), Person4]
}
]
]
];
then get an error :
onError type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'Person4'

The getter 'name' was called on null.

While having the #22 issue (and a few times before but because I was making another mistake) I had this error:

NoSuchMethodError: The getter 'name' was called on null.
Receiver: null
Tried calling: name
STACKTRACE: 
#0      Object._noSuchMethod (dart:core-patch/object_patch.dart:43)

#9      fromJson (package:dson/src/deserializer.dart:27:10)

It appears to come from:

  IncorrectTypeTransform(Object value, String type, [String key = "unknown"]) :
    _type = type,
    _field = key,
    _foundType = reflectType(value.runtimeType).name;

The problem appeared in the past when I forgot to call _initMirrors();
That was a hard one because the original Exception is hidden by this Exception in... Exception management.

However, I had it again when hitting #22 because type issues on native types are managed like that (on deserializer):

 else if (valueType == String) {
    if (value is String) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'String', key);
    }
  } else if (valueType == num) {
    if (value is num) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'num', key);
    }
  } else if (valueType == int) {
    if (value is int) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'int', key);
    }
  } else if (valueType == double) {
    if (value is double) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'double', key);
    }
  } else if (valueType == bool) {
    if (value is bool) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'bool', key);
    }
  } else if (valueType == 'list') {
    if (value is List) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'list', key);
    }
  } else if (valueType == Map) {
    if (value is Map) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'Map', key);
    }

but for me all these IncorrectTypeTransform() returns the same Exception because reflectType(bool) is null.
This is because base Dart types are not added to _classMirrors (and they don't need to, do they?)

Enums not serialized to json/map

Hi,
I'm sorry to bother again, but it seems enums are not being serialized.
TransactionType in the class below throws an exception when serializing to map:

library example.object_to_json; // required by dson
import 'package:dson/dson.dart';
import 'package:ucount_flutter/codes/cdefines.dart';
part 'package:ucount_flutter/entities/etransaction.g.dart';//required by dson

@serializable
class ETransaction extends _$ETransactionSerializable{
  int id;
  TransactionType transactionType;
  int userID;
  String title;
  String description;
  double total;
  int categoryID;
  int vendorID;
  DateTime dt;
  DateTime dateInserted;

  ETransaction({this.userID,this.title,this.total,this.dt, this.transactionType, this.id});

  noSuchMethod(Invocation invocation) => super.noSuchMethod(invocation);
}

Here is the TransactionType enum:

Extending generic class leads to error

Hello.
I changed sample in extend_serializables to generic to emulate my real case Derived => Base<T>

  DateTime dateOfBirth;
}

@serializable
// ignore: mixin_inherits_from_not_object
class Employee extends Person<String> with _$EmployeeSerializable {
  double salary;
}

and got an issue:

Convert Lists<ModelClass> to ModelClass objects is incorrect

I notice that use 'fromMap' to convert json who contain list Model to dart List Model is not work.

It works OK, after i modify some code.

the following illustrate is Inappropriately

it should be: 
 List<Person> persons = fromMap([{"id": 1, "name": "John Doe"}], [List<Person>(), Person]);

modify the '_convertValue' function code in deserializer.dart of dson_core

append ' = valueType[0]; ' after 'var receiver'

Then it works well.

BTW: i think the Map conversion has same issue.

the method [] was called on null

pretty much when i saw where it was coming from i said:

so how do i _initMirrors() when I don't have an _initMirrors()?

as i see it i need an _initMirrors() function from somewhere but i don't have one. i see it in your examples.

update: I think i know where to get an _initMirrors() function, but my main and all the things that need serializing are seperate, so i don't think it'll give my main.dart a main.g.dart with a _initMirrors() function

Please, merge bootstrap_sass

dart-league/bootstrap_sass#13

Sorry to create this issue. But this is the package currently undergoing updates within your organization.

Best regards

Think about this: List of random typed objects

Think about a list of random typed objects.

how would you deal with them?

Maybe try storing their type name with them.

I did it, but i don't know how your code works so i can't put it in yours, but a push in the right direction might be

{
  'data': new SerializableBaconSomething(shouldDo:true,),
  'type': SerializableBaconSomething,
}

Also, look at my package: server_client_comm

deserialize int to double if required

Hello,

1st, thanks for this package that has been really helpful!

Now I have a little issue with JSON ints that I want to map to double (because I know this can be "1.5", but when it's "1.0" the server returns just "1").
It's rejected by:

else if (valueType == double) {
    if (value is double) {
      return value;
    } else {
      throw new IncorrectTypeTransform(value, 'double', key);
    }
  }

This could be:

else if (valueType == double) {
    if (value is double) {
      return value;
    } else if(value is int) {
     return value.toDouble();
  } else {
      throw new IncorrectTypeTransform(value, 'double', key);
    }
  }

The conversion is possible the other way (double => int) but it's much more dangerous. Here we just cast to a larger class.

A versão do collection do Adson, está dando conflito com a versão do flutter 3.10

No seu caso específico, o pacote “flutter_fros_sak” depende da versão 1.17.1 da biblioteca “collection”, enquanto o pacote “dson” depende da versão “^1.17.2” da mesma biblioteca. Isso cria um conflito, pois essas versões não são compatíveis entre si.

Além disso, a versão 2.0.0 do pacote “dson” não oferece suporte à segurança de nulos (null safety), o que torna o pacote incompatível com o “flutter_fros_sak” e outros pacotes que dependem de null safety.

Add possibility to deserialize to immutable object

It would be nice if DSON supported immutable objects. I always make my data transfer objects immutable. This makes them safe to share in all code and also to cache. Here is an example:

class FooDto {
  final Guid id;
  final String name;
  FooDto(this.id, this.name);
}

In order to deserialize the constructor must be called and the keys in the JSON matched to the names of the constructor params. I saw no examples of this (but have not tried so maybe it already works?).

How does the generic works?

this library seems doesn't support generic.

library entity.ApiResponse;
import 'package:dson/dson.dart';

part 'ApiResponse.g.dart';
@serializable
class ApiResponse<T> extends _$ApiResponseSerializable{
    int code;
    String toast;
    String message;
    T data;
}

and i compile it ,it's wrong.

Classes for mirrors only detected when directly imported

This might be an issue with built_mirrors

Mirrors are not being generated if the class imported through an export.

setup
model.dart contains annotated class
intermediate.dart contains export "model.dart"

working
main.dart imports model.dart
main.g.dart has initClassMirrors({Control: ModelClassMirror});
Mirrors are generated

failing
main.dart imports intermediate.dart
main.g.dart has initClassMirrors({});
Mirrors are not generated, because the Model doesn't seem to be picked up

Unable to generate _initMirrors()

serialization fails as _initMirrors() could not be generated

recommend updates to readme/install

Given a standard flutter install, and a new user, I recommend some updated to the README.md for setup/install and initial usage.

The user needs to add build_runner as a dev_dependency within their pubspec.yaml. For example
```
dev_dependencies:
  build_runner:
```
The pre-build command is slightly different with the flutter toolset. The following is used instead: flutter packages pub run build_runner build
The relationship of the library naming, the part naming, and the current requirement to have them all in a single file with the main() function can be difficult to learn at the beginning. I recommend a review of these topics along with their limitations due to #30. Afterwards, to clarify the README.

static

I just want to say

@serializable
Class AbsoluteEgg {
 static String youJustGotBeaned = "tag your friends to totally bean them!";
}

youJustGotBeaned does not exist on class AbsoluteEgg

and yes I am being serious.

_initMirrors not being generated

I followed along with the README, but it seems _initMirrors() is not being generated if I define the following file:

lib/src/models/models.dart

library my_lib.models;

import 'package:dson/dson.dart';

part 'models.g.dart';

@serializable
class Person extends _$PersonSerializable {
  int id;
}

tool/build.dart

import 'package:build_runner/build_runner.dart';
import 'package:dson/action.dart';

main() async
{
  await build([dsonAction(const ['lib/src/models/**.dart'])], deleteFilesByDefault: true);
}

yields:
lib/src/models/models.g.dart

// GENERATED CODE - DO NOT MODIFY BY HAND

part of my_lib.models;

// **************************************************************************
// Generator: DsonGenerator
// **************************************************************************

abstract class _$PersonSerializable extends SerializableMap {
  int get id;
  void set id(int v);

  operator [](Object __key) {
    switch (__key) {
      case 'id':
        return id;
    }
    throwFieldNotFoundException(__key, 'Person');
  }

  operator []=(Object __key, __value) {
    switch (__key) {
      case 'id':
        id = __value;
        return;
    }
    throwFieldNotFoundException(__key, 'Person');
  }

  Iterable<String> get keys => PersonClassMirror.fields.keys;
}

// **************************************************************************
// Generator: MirrorsGenerator
// **************************************************************************

_Person__Constructor([positionalParams, namedParams]) => new Person();

const $$Person_fields_id = const DeclarationMirror(name: 'id', type: int);

const PersonClassMirror = const ClassMirror(
    name: 'Person',
    constructors: const {
      '': const FunctionMirror(name: '', $call: _Person__Constructor)
    },
    fields: const {
      'id': $$Person_fields_id
    },
    getters: const [
      'id'
    ],
    setters: const [
      'id'
    ]);

Notice the generated file lacks _initMirrors, making it useless.

null safety support

trying to add the package gives error

❰mac❙~/android(git✱≠✱main)❱✔≻ flutter pub add dson                                                                                                 4.4m  Fri May 26 11:04:23 2023
The current Dart SDK version is 3.0.2.

Because * depends on dson any which doesn't support null safety, version solving failed.

The lower bound of "sdk: '<2.0.0 or >=2.0.0-dev <3.0.0'" must be 2.12.0 or higher to enable null safety.
For details, see https://dart.dev/null-safety

Update `serializable_core` dependency version in pubspec

I tried this package just today and ran into the 'Missing concrete implementations of Map methods' error.

I noticed it stemmed from the serializable_core package, and you've since pushed a new release for it.
I suggest you please update the dson's pubspec as well, so us users can pull the new version 👍

Thanks for your efforts!

Is dson supposed to work for browser application?

what's with the `?.isFinal == true` ? it's erroring me out!

like, the other day, this happened: bla bla bla positionalParams has a length of 0 RangeError ooee blamo.

and it's been happening ever since.

Property annotation conflicts with Polymer 1.0 Property annotation

I know it's easy to workaround importing dson library with 'as' keyword, just thinking maybe it would be better to avoid this at all by renaming it to something else, like DsonProperty, for example.
But think twice about that because it would be a breaking change. May be it would be enough to put a note about that in the docs.
