Add feedback when users reset completed chapters.

[thetimileyin]

At present when users reset completed chapters, they can’t tell if the chapters have truly been reset since there is no feedback or reaction for the action taken so they keep tapping and tapping till they go back to the 'Learn' tab and see that the chapters have actually been reset. We could add a flash message (pop-up) to let users know that their action has been reacted to. This will help improve user experience on the app.

I actually worked out a solution for this on the design part

Here is also a link to the prototype: https://www.figma.com/proto/nCbd7WyTtWsd4GxtLu1vQC/Untitled?node-id=1%3A23&scaling=scale-down&page-id=0%3A1&starting-point-node-id=1%3A23

Nice work! I think adding an interaction there makes perfect sense. On the engineering side I think this would be a good use of a snackbar (for the devs reading this).

I have done a similar work in #242. I can take this up also.
