my code:

    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username

if __name__ == '__main__':
    db.create_all() 

Answer 1

Add the SQLALCHEMY_TRACK_MODIFICATIONS configuration key to the flask app.

app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False

With this at the time of instantiating the application at the instance of Flasksqlalchemy will not be shown.
