EdgeFactory<T extends Edge> class abstract

Factory interface for creating edge instances from JSON data.

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

Example:

class FriendshipEdgeFactory implements EdgeFactory<FriendshipEdge> {
  @override
  FriendshipEdge fromJson(Map<String, dynamic> json) {
    return FriendshipEdge(
      from: json['from'] as String,
      to: json['to'] as String,
      weight: (json['weight'] as num).toDouble(),
    );
  }
}
