自定义计时器

Custom Timer ⌛

A Flutter package to create a customizable timer.

🎉 Features

• Timer controller.
• Auto count up / down timer.
• Custom builder.
• Millisecond support.

📌 Usage

Add SingleTickerProviderStateMixin to your stateful widget. 👇

class _MyAppState extends State<MyApp> with SingleTickerProviderStateMixin {

Then define a CustomTimer controller

late CustomTimerController _controller = CustomTimerController(
  vsync: this,
  begin: Duration(hours: 24),
  end: Duration(),
  initialState: CustomTimerState.reset,
  interval: CustomTimerInterval.milliseconds
);

And you are ready to use the timer:

CustomTimer(
  controller: _controller,
  builder: (state, time) {
    // Build the widget you want!🎉
    return Text(
      "${time.hours}:${time.minutes}:${time.seconds}.${time.milliseconds}",
      style: TextStyle(fontSize: 24.0)
    );
  }
)

Now you can use the controller methods:

_controller.reset();
_controller.start();
_controller.pause();
_controller.finish();

_controller.add(Duration(minutes: 30));
_controller.subtract(Duration(minutes: 30));
_controller.jumpTo(Duration(hours: 12));

You can also set the begin or end, even with the counter running:

_controller.begin = Duration();
_controller.end = Duration(hours 12);

And add listeners to state changes or just use the properties when you need them:

_controller.state.addListener(() {
  print(_controller.state.value); // 👉 CustomTimerState.paused
  print(_controller.remaining.value.hours); // 👉 12h
});

Remember to dispose when you are no longer using it.
