In this tutorial, we implemented the Flutter Countdown Timer using the easiest approach. We used the timer.perodic constructor to build the timer and then saw different use cases in which you can use the countdown timer. Finally, we saw the ready-made solution using the package. ...

It is already a part of the Flutter SDK and can be imported with the following: import 'package:async/async.dart'; With it imported, we can create a simple 3 second RestartableTimer: final restartableTimer = RestartableTimer( const Duration(seconds: 3), () { //Callback }, ); //...
尝试Future.delayed而不是Timer
Timer.periodic是Flutter中的一个定时器类,用于创建一个重复定时任务。它接受两个参数:一个Duration类型的时间间隔和一个回调函数。每隔指定的时间间隔,回调函数就会被调用一次。 使用Timer.periodic可以实现很多定时任务,例如轮询后端接口获取数据、定时刷新界面等。 Timer.periodic的优势在于它的简单易用性和灵活性。通过...
