time_listener

An extremely easy-to-use flutter plugin that allows you to listen time changes.

Features

This package makes very easy to listen time changes using a stream. The code responsible for checking time diff is run in an isolate, so you don't have to worry about performance.

Usage

To start listening create instance of the class and call "listen" method on it. Stream event with the new date will come every second.

  // actively listen for time updates with the interval specified in parameter
  // until listener.cancel() is called
  final listener = TimeListener()..listen((DateTime dt) {
  print('${dt.hour}:${dt.minute}:${dt.second}');
  });

  // don't forget to cancel listener when it is no longer needed
  // so the program doesn't run forever
  await listener.cancel();

To specify interval (by default every minute) you can use custom factory.

  // below code will emit new DateTime every minute without seconds precision
  // output - 21:37:00
  final listener = TimeListener()..listen((DateTime dt) {
  print('${dt.hour}:${dt.minute}:${dt.second}');
  });

  // but if you need u can specify more precise interval with custom factory
  // output - 21:37:24
  final listener = TimeListener.create(interval: CheckInterval.seconds)..listen((DateTime dt) {
  print('${dt.hour}:${dt.minute}:${dt.second}');
  });
