🖥️ Environment

• Operating System: Windows 11
• Application Version: vaden 1.0.2
• Dart: 3.11.1

📝 Detailed Description

Ao usar a anotação @JsonDefault com tipos int ou double,
o build_runner gera código Dart inválido usando int() e double()
como construtores, que não existem no Dart.

🔄 Steps to Reproduce

1. Criar um DTO com @JsonDefault em campos int ou double
2. Executar dart run build_runner build
3. Verificar o arquivo gerado vaden_application.dart

Code

@dto()
class CreateEarningRequest {
@jsonkey('month_id')
final int monthId;

@JsonDefault('SALARIO')
final String name;

@jsonkey('gross_value')
@JsonDefault(1000.0)
final double grossValue;

@jsonkey('net_value')
@JsonDefault(800.0)
final double netValue;

@jsonkey('earning_date')
@JsonDefault('2026-03-05')
final String earningDate;

CreateEarningRequest({
required this.monthId,
required this.name,
required this.grossValue,
required this.netValue,
required this.earningDate,
});
}

✅ Expected Result

#monthId: json.containsKey('month_id') ? json['month_id'] : 0,
#grossValue: json.containsKey('gross_value') ? json['gross_value'] : 6200.0,

❌ Actual Result

#monthId: json.containsKey('month_id') ? json['month_id'] : int(0),
#grossValue: json.containsKey('gross_value') ? json['gross_value'] : double(6200.0),
