Usage #
To use the widget, import the package in your project
import 'package:simple_timer/simple_timer.dart';
The timer can be controlled in two ways:
-
Using a TimerController (preferred) - The TimerController is a convenience wrapper (subclass) of an AnimationController and needs a TickerProvider, so be sure to extend a TickerProvider in your class. Declare and instantiate your timer controller like below:
// declaration TimerController _timerController; // instantiation _timerController = TimerController(this);
Note: Remember to dispose the TimerController
and set the controller property to the TimerController object like below:
Container( child: SimpleTimer( controller: _timerController, duration: Duration(seconds: 10), ) )
TimerController methods:
Method Description start Starts the timer e.g. (_timerController.start()) pause Pauses the timer e.g. (_timerController.pause()) reset Resets the timer e.g. (_timerController.reset()) restart Restarts the timer e.g. (_timerController.restart()) add Increases time left by the specified duration i.e. allows more time e.g. (_timerController.add(Duration(seconds: 10))) subtract Decreases time left by the specified duration i.e. reduces the time e.g. (_timerController.subtract(Duration(seconds: 10))) -
Setting the Status - The timer can also be controler by passing a TimerStatus value to the status property; like below:
Container( child: SimpleTimer( status: TimerStatus.start, duration: Duration(seconds: 10), ) )
Note: The SimpleTimer widget uses its parent size.
