Some things should happen once.

• Users should only get the guided tour once.
• Release notes should only pop up once every new app version comes.
• Etc.. once every (Whatever you want).

Once supports runOnce, runOnEveryNewVersion, runEvery12Hours, runHourly, runDaily, runWeekly, runMonthly, runOnNewMonth, runYearly and Custom (Duration).

Usage

Mainly runner functions consists of callbacks and fallbacks

• callback are the generic functions that run and returns a future<T?> .
• fallback are the same but only runs in case if that callback future returns null.

Now you're ready to go. Say you wanted to show the new features dialog when the app is updated:

Once.runOnEveryNewVersion(
  callback: () {
    /* What's new in 2.3.2 version? dialog */
  },
  fallback: () {
   /* Navigate to new screen */
  },
);

Or maybe you want to show the rate this app dialog every week for the user:

if (!rated) {
  Once.runWeekly("ratingDialog",
    callback: () { 
       /* Like our app, Please rate us. dialog */ 
    },
    fallback: () {
      /* Thanks */
    },
  );
}
