[prudhvi-hack]

Hey ,I liked the app and tried building it for linux with some changes and it is stable.As the work you need to do is less Try giving support to linux and add to snapstore.
Things i changed

• used ffi implementation of sqflite package.
• Changed sizes and fonts

Things not worked but i didn't cared

• Login system

It is a very nice app thanks.

Note:-I removed all of the feedback wall as i don't need

Hi, when I created this project,I didn't plan to build it on web or desktop
But now flutter can do more in web and desktop, so if I have time, I'll make it support for desktop and web, it may need lots of time
