Classes with null safety and JSON serialization
Frequently Asked Questions
What Dart features are supported?
The generator creates Dart classes with proper type safety, supports both manual JSON serialization and json_annotation package, uses nullable types for null values, and follows Dart naming conventions.
How does json_annotation work?
When json_annotation framework is selected, generated classes use @JsonSerializable() annotation and generate fromJson/toJson methods automatically with build_runner. This provides type-safe JSON serialization.
How are nullable values handled?
Null values in JSON are mapped to nullable types (?) in Dart, providing null safety. Required fields use 'required' keyword in constructors, following Dart's null safety principles.
What about Dart's type system?
Generated Dart code leverages Dart's strong type system with appropriate types (int, double, String, bool, List, Map) and follows Dart conventions like camelCase for field names.
