New Feature: Random reminders

[Ranger-NF]

This PR includes the feature requested in #50. New button random reminders in settings menu.

How it works?

Every time the random reminders button is pressed, app calculates completely random time and sets an alarms using existing system.

Limitations:

Once set, the time will be same everyday (Although it can be changed by pressing the above mentioned button again).

I wasn't able to come up with a good solution for this without making it complicated.

Forgot to pull latest changes. Let me fix it

Awesome work! It may be a bit before I merge this in as I want to give some thought to how to do the following:

• Make the time change everyday (without allowing more than once per day)
• Let the user bound the random time If I can figure that out I think this could be the new default alarm behavior. Thanks again!

Oh okay, thats fine by me. Do you want me to close this PR?

@Ranger-NF Odd, that package is in the process of being overhauled by the main developer so it may have just fallen out of date. Can you try lowering your flutter SDK version to 3.16.0 again? It looks like this branch is on 3.18.0.

@Ranger-NF No feel free to leave it open! If I come up with those changes I will use this PR as a base so you get credit for the merge 😊

[Ranger-NF]

Okay, it should be working properly now
