Implementation

@override

  try {
    final localTasks = await localDataSource.getTasks(projectId: projectId);
    if (localTasks.isNotEmpty) {

    }

    final remoteTasks =
        await remoteDataSource.getTasks(projectId: projectId!);
    await localDataSource.saveTasks(remoteTasks);
    return Right(remoteTasks.map((t) => t.toEntity()).toList());
  } on ServerFailure catch (e) {
    return Left(e);
  } catch (e) {
    return Left(ServerFailure(message: 'Unexpected Error ${e.toString()}'));
  }
