RequiredSizeConverter class

A non-nullable JSON converter for Flutter's Size class.

Similar to SizeConverter but for non-nullable Size fields. This converter serializes Size objects to JSON as a map with 'width' and 'height' keys, and deserializes JSON maps back to Size objects.

Usage with json_serializable:

@JsonSerializable()
class MyClass {
  @RequiredSizeConverter()
  final Size dimensions;

  MyClass(this.dimensions);
}
