📦 Partitioned Blocs

In most application, it’s common to want to create multiple partitions to have multiple states for the same bloc. For example:

• Separate documents
• Unique social feeds

Making a Bloc Partitioned

Simply override the id getter in your bloc to be the unique ID for that state:

import 'package:blocsync/blocsync.dart';

class DocumentBloc extends SyncedBloc<DocumentEvent, DocumentState> {
  DocumentBloc({
    required String documentId,
  }) : _documentId = documentId,
   super(DocumentState.initial()) {
    on<UpdateTheme>((event, emit) => emit(state.copyWith(theme: event.theme)));
    on<UpdateLanguage>((event, emit) => emit(state.copyWith(language: event.language)));
  }

  final String _documentId;

  @override
  bool get id => _documentId; // This makes the bloc store each document separately

  @override
  DocumentState fromJson(Map<String, dynamic> json) => DocumentState.fromJson(json);

  @override
  Map<String, dynamic>? toJson(DocumentState state) => state.toJson();
}
