I have a fully functional app created in ***Flutter***. It uses [***sqflite***](https://pub.dev/packages/sqflite) plugin for storing data. I want to have a data change listener, which will update or refresh the data when new data is added or updated. How can I achieve this. I came across a sqflite helper plugin [***sqlcool***](https://pub.dev/packages/sqlcool) but could not figure out a way to use it with my existing database in sqflite. Please help me.  

Thanks.
