Getting started

This plugin is in beta, We are working on it to improve it.

Install

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  animated_wizard_bar: <latest_version>

Usage

first of all you have to write this code in your main dart file :

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import 'package:provider/single_child_widget.dart';
import 'package:animated_wizard_bar/custom_page_view_screen.dart';
import 'package:animated_wizard_bar/page_view/custom_page_viewmodel.dart';
import 'package:animated_wizard_bar/page_view/wizrdbar_viewmodel.dart';
import 'package:flutter_tabler_icons/flutter_tabler_icons.dart';
import 'package:animated_wizard_bar/page_view/widgets/custom_page_view_package.dart';
import 'package:animated_wizard_bar/page_view/widgets/step_horizontal_animation.dart';
import 'package:animated_wizard_bar/page_view/widgets/wizardbar_animation.dart';

void main() {
  runApp(multiProvider);
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: const WizardExample(),
    );
  }
}

List<SingleChildWidget> providers = [
  ChangeNotifierProvider<CustomPageViewModel>(
    create: (context) => CustomPageViewModel(),
  ),
  ChangeNotifierProvider<WizardBarViewModel>(
    create: (context) => WizardBarViewModel(),
  ),
];
MultiProvider multiProvider = MultiProvider(providers: providers, child: const MyApp());

in class you want use animated wizard bar package

class ExampleWizard extends StatefulWidget {
  const ExampleWizard({
    super.key,
  });

  @override
  State<ExampleWizard> createState() => _ExampleWizardState();
}

class _ExampleWizardState extends State<ExampleWizard> with TickerProviderStateMixin {
  final singleChildScrollControllerWizardBar = ScrollController();

here you have to create instance of global key for your StepHorizontalAnimation widgets and after that create list

  var key1 = GlobalKey();
  var key2 = GlobalKey();
  var key3 = GlobalKey();
  var key4 = GlobalKey();
  var key5 = GlobalKey();

  List<Animation<double>> animationList = [];
  List<AnimationController> aniControllerList = [];
  List<Widget> pageViewList = [
    Container(
      color: Colors.amber,
      child: const Center(
        child: Text('0'),
      ),
    ),
    const Center(
      child: Text('1'),
    ),
    const Center(
      child: Text('2'),
    ),
    const Center(
      child: Text('3'),
    ),
    const Center(
      child: Text('4'),
    ),
    // const Center(
    //   child: Text('5'),
    // )
  ];

in init state of your class you must animation controller list for youe StepHorizontalAnimation widgets .

  @override
  void initState() {
     // Initialize animation controllers with the same configuration.
    aniControllerList = List.generate(
      // 5 is number of animation controller you want generated
      5,
      (_) => AnimationController(
        vsync: this, // Provides the Ticker for animations.
        duration: const Duration(milliseconds: 800), // Forward animation duration.
        reverseDuration: const Duration(milliseconds: 800), // Reverse animation duration.
      )..addListener(() {}), // Listener can be used for additional behavior.
    );

    // Create scale animations for each step using the animation controllers.
    animationList = aniControllerList.asMap().entries.map((entry) {
      int index = entry.key;
      AnimationController controller = entry.value;
      if (index == 0) {
        return Tween<double>(begin: 0.95, end: 1.35).animate(controller);
      } else {
        return Tween<double>(begin: 1.35, end: 0.95).animate(controller);
      }
    }).toList();

    // Start all animations in the forward direction.
    for (var controller in aniControllerList) {
      controller.forward();
    }


    super.initState();
  }

here you must create instance list of StepHorizontalAnimation :

pay Attention :

The length of the steps list must be equal to the length of the pageViewList.

  @override
  Widget build(BuildContext context) {
    List<StepHorizontalAnimation> stepsList = [
      StepHorizontalAnimation(
        filled: true,
        boxKey: key1,
        icon: TablerIcons.user,
        visibleLeft: true,
        itemsNeedForFilled: 9,
        stepsNumber: 0,
        scaleAnimation: animationList.elementAt(0),
        scaleAnimationList: aniControllerList,
        scrollController: singleChildScrollControllerWizardBar,
        canSelect: false,
        // enable: true,
      ),
      StepHorizontalAnimation(
        filled: false,
        boxKey: key2,
        icon: TablerIcons.home_check,
        visibleLeft: true,
        itemsNeedForFilled: 7,
        stepsNumber: 1,
        scaleAnimation: animationList.elementAt(1),
        scaleAnimationList: aniControllerList,
        scrollController: singleChildScrollControllerWizardBar,
        canSelect: false,
        // enable: true,
      ),
      StepHorizontalAnimation(
        filled: false,
        boxKey: key3,
        icon: TablerIcons.briefcase,
        visibleLeft: true,
        itemsNeedForFilled: 10,
        stepsNumber: 2,
        scaleAnimation: animationList.elementAt(2),
        scaleAnimationList: aniControllerList,
        scrollController: singleChildScrollControllerWizardBar,
        canSelect: true,
        // enable: true,
      ),
      StepHorizontalAnimation(
        filled: false,
        boxKey: key4,
        icon: TablerIcons.users,
        visibleLeft: true,
        itemsNeedForFilled: 13,
        stepsNumber: 3,
        scaleAnimation: animationList.elementAt(3),
        scaleAnimationList: aniControllerList,
        scrollController: singleChildScrollControllerWizardBar,
        canSelect: false,
        // enable: true,
      ),
      StepHorizontalAnimation(
        filled: false,
        boxKey: key5,
        icon: TablerIcons.building_store,
        visibleLeft: false,
        itemsNeedForFilled: 1,
        stepsNumber: 4,
        scaleAnimation: animationList.elementAt(4),
        scaleAnimationList: aniControllerList,
        scrollController: singleChildScrollControllerWizardBar,
        canSelect: false,
        // enable: true,
      ),
    ];
    final getCustomPageViewModel = Provider.of<CustomPageViewModel>(context, listen: false);
    return WillPopScope(
      onWillPop: () async {
        if (getCustomPageViewModel.currentLevel == 0) {
          return true;
        } else {
          getCustomPageViewModel.previousPage(aniControllerList, singleChildScrollControllerWizardBar, stepsList.length, stepsList[getCustomPageViewModel.currentLevel].boxKey);
          return false;
        }
      },
      child: SafeArea(
        child: Scaffold(
          body: CustomPageView(
            appBar: AppBar(
              title: const Text(
                'animated wizard bar',
              ),
              centerTitle: true,
            ),
            pageViewItems: pageViewList,
            aniController: aniControllerList,
            stepsList: stepsList,
            singleChildScrollController: singleChildScrollControllerWizardBar,
            wizardBarAnimation: WizardBarAnimation(singleChildScrollControllerWizardBar, stepsList),
          ),
