flutter_once

Built on once.

Want to show a widget once periodically (Daily - Weekly - Monthly - Yearly - Any period)? We got you.

Some widgets should show OnceWidget.

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

OnceWidgets supports showOnce, showOnEveryNewVersion, showEvery12Hours, showHourly, showDaily, showWeekly, showMonthly, showOnNewMonth, showYearly and Custom (Duration).

Usage

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:

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