NodeFactory<T extends Node> class abstract

Factory interface for creating node instances from JSON data.

Implement this interface to provide deserialization logic for your custom node types. This is used by Box.loadNode to convert JSON data back into node objects.

Example:

class PersonNodeFactory implements NodeFactory<PersonNode> {
  @override
  PersonNode fromJson(Map<String, dynamic> json) {
    return PersonNode(
      id: json['id'] as String,
      name: json['name'] as String,
      age: json['age'] as int,
    );
  }
}
