Usage

Once

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 */
    },
  );
}

OnceWidget

Mainly builder functions consists of builders and fallbacks

• builder is the generic function that shows and returns a Widget .
• fallback is the same but only shows in case that callback future returns null (defaults to SizedBox.shrink()).

Now you're ready to go. Say you wanted to view a banner widget when the app is updated:

OnceWidget.showOnEveryNewVersion(
  builder: () {
   return Container(...);
  },
);

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

OnceWidget.showWeekly("ratingDialog",
  builder: () {
     return Text('Hello, New Week');
   },
  fallback: () {
     return Text('Hello!');
   },
);
