Note: This page is built with flutter-web, hence the animations may not be smooth. For a better user experience, please run the example app on a mobile device.

Installation

Add animated_counter: 1.0.0 to your pubspec.yaml dependencies. And import it:

import 'package:collapsible_sidebar/collapsible_sidebar.dart';

How to use

---

First create the object of the Animated Counter you wish to use. Then use its build() method to build it. Finally use the incrementCounter(), decrementCounter() and getCounter() methods to control the widget animations.

Create the object of the animated counter you like

  BlocksCounter block = BlocksCounter(initialCounter: 0);
  DisksCounter disk = DisksCounter(initialCounter: 0);
  WaveCounter wave = WaveCounter(initialCounter: 0);
  CircleWaveCounter circle;
  RotatingBubblesCounter bub = RotatingBubblesCounter(initialCounter: 0, initialColors: [Colors.red, Colors.green, Colors.blue]);
  RotatingPlanetsCounter plan = RotatingPlanetsCounter(initialCounter: 0, initialColors: [Colors.red, Colors.green, Colors.blue]);
  CreatureCounter cre;
  ImageBubbleCounter imgbub = ImageBubbleCounter(initialCounter: 0, image: 'assets/dash.jpg');
  PortraitCounter por = PortraitCounter(initialCounter: 0, image: 'assets/mattis.jpeg');
  ParticlesCounter part;
  VolcanoCounter vol = VolcanoCounter(initialCounter: 0, enableSky: true);
  PixelCounter pix = PixelCounter(initialCounter: 0);

  @override
    void initState() {
      circle = CircleWaveCounter(vsync: this, initialCounter: 0, initialColors: [Colors.red, Colors.green, Colors.blue]);
      cre = CreatureCounter(vsync: this, initialCounter: 0, initialColors: [Colors.red, Colors.green, Colors.blue]);
      part = ParticlesCounter(initialCounter: 0, images: ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg', 'image5.jpg']);
      super.initState();
    }

CircleWaveCounter() and CreatureCounter() require a vsync hence the parent class needs to extend TickerProviderStateMixin to use these counters.

Use it in widget tree using build() method. Control it using the incrementCounter(), decrementCounter() and getCounter() methods.

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: PageView(
        children: [
          block.build(context),
          disk.build(context),
          wave.build(context),
          circle.build(context),
          bub.build(context),
          plan.build(context),
          cre.build(context),
          imgbub.build(context),
          por.build(context),
          part.build(context),
          vol.build(context),
          pix.build(context),
        ],
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: (){
          setState(() {
            block.incrementCounter();
            disk.incrementCounter();
            wave.incrementCounter();
            circle.incrementCounter();
            bub.incrementCounter();
            plan.incrementCounter();
            cre.incrementCounter();
            imgbub.incrementCounter();
            por.incrementCounter();
            part.incrementCounter();
            vol.incrementCounter();
            pix.incrementCounter();
          });
        },
      ),
    );
  }
