Python Flask Blueprint with classes

I am looking at moving to blueprints in Flask, but the current implementation passes the flask app instance into a class as part of the init(), how do I do this with blueprints please?

def __init__(self, flask_instance, logger, event_manager):
    self._logger = logger
    self._flask = flask_instance
    self._event_manager = event_manager

    # Add route : /management/add
    self._quart.add_url_rule('/job/new_job',
        methods = ['POST'], view_func = self._new_job)

You put the blueprint into the class construction

class Test(object):
    blueprint = Blueprint("Test", __name__)
    def __init__(self, db_host, db_port):
        self.db_host = db_host
        self.db_port = db_port
    def loadDb(self):
        return Connection(self.db_host, self.db_port)
    @blueprint.route("/<var>")
    def testView(var): # adding self here gives me an error
        return render_template("base.html", myvar=self.loadDb().find({"id": var})
