Rocket Timer #
The rocket_timer package provides a RocketTimer class for implementing countdown or normal timers in Flutter applications, as well as a RocketTimerBuilder widget for building widgets that respond to changes in a RocketTimer object. It supports starting, pausing, stopping, resetting, and switching between countdown and normal modes, and is easy to use and customize.
Usage #
To use the RocketTimer class, simply create a new instance of it and call its methods to control the timer:
import 'package:rocket_timer/rocket_timer.dart';

final RocketTimer timer = RocketTimer(duration: 60, type: TimerType.countdown);

// Start the timer
timer.start();

// Pause the timer
timer.pause();

// Stop the timer
timer.stop();

// Reset the timer
timer.reset();

// Switch between countdown and normal modes
timer.switchMode();

To display the timer in a widget, you can use the RocketTimerBuilder widget which listens to changes in a RocketTimer object and rebuilds the widget tree accordingly:
import 'package:flutter/material.dart';
import 'package:rocket_timer/rocket_timer.dart';

class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);

final String title;

@override
_MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
final RocketTimer _rocketTimer = RocketTimer(duration: 60, type: TimerType.countdown);

@override
void dispose() {
_rocketTimer.dispose();
super.dispose();
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: RocketTimerBuilder(
timer: _rocketTimer,
builder: (BuildContext context) {
return Text(
_rocketTimer.formattedDuration,
style: Theme.of(context).textTheme.headline1,
);
},
),
),
);
}
}
