dson adapter

DSON #
Convert JSON to Dart Class withless code generate(build_runner).
A simple Object #
class Person {
final int id;
final String name;
final int age;

Person({
required this.id,
required this.name,
required this.age,
});
}

Convert json to Object:
main(){
final jsonMap = {
'id': 1,
'name': 'Joshua Clak',
'age': 3,
};

Person person = dson.fromJson(jsonMap, Person.new);

print(person.id);
print(person.name);
print(person.age);
}

A complex object: #
For complex objects it is necessary to declare the constructor in the inner property;
main(){
final jsonMap = {
'id': 1,
'name': 'MyHome',
'owner': {
'id': 1,
'name': 'Joshua Clak',
'age': 3,
},
};

Person person = dson.fromJson(
jsonMap,
Person.new,
inner: {
'owner': Person.new,
}
);

print(person);
}

A complex object with List: #
For work with a list, it is necessary to declare the constructor in the inner property and declare
the list resolver in the resolvers property.
main(){
final jsonMap = {
'id': 1,
'name': 'MyHome',
'owner': {
'id': 1,
'name': 'Joshua Clak',
'age': 3,
},
'parents': [
{
'id': 2,
'name': 'Kepper Vidal',
'age': 25,
},
{
'id': 3,
'name': 'Douglas Bisserra',
'age': 23,
},
],
};

Home home = dson.fromJson(
// json Map or List
jsonMap,
// Main constructor
Home.new,
// external types
inner: {
'owner': Person.new,
'parents': ListParam<Person>(Person.new),
},
);

print(home);
}

DSON Have ListParam and SetParam for collection.
When API replace Param Name (Set aliases): #
You need to declare within the aliases map the object type that has changed in the key, and in the value, a map with the old key as the key and the new key as the value.
main(){
final jsonMap = {
'id': 1,
'name': 'MyHome',
'master': {
'key': 1,
'name': 'Joshua Clak',
'age': 3,
},
'parents': [
{
'key': 2,
'name': 'Kepper Vidal',
'age': 25,
},
{
'key': 3,
'name': 'Douglas Bisserra',
'age': 23,
},
],
};

Home home = dson.fromJson(
// json Map or List
jsonMap,
// Main constructor
Home.new,
// external types
inner: {
'owner': Person.new,
'parents': ListParam<Person>(Person.new),
},
// Param names Object <-> Param name in API
aliases: {
Home: {'owner': 'master'},
Person: {'id': 'key'}
}
);

print(home);
