GSStepper

GSStepper is a Flutter package that provides a custom stepper widget. It allows you to create a step-by-step process in your application, guiding users through multiple stages or tasks. The widget offers the flexibility to choose between scrolling or fixing the stepper based on your needs.

You can customize the stepper to fit your application's design by setting various properties such as colors, sizes, icons, and labels. Plus, you can easily track the user's progress by updating the status and progress values of each step.

Installation

To use this package, add gsstepper as a dependency in your pubspec.yaml file.

flutter pub add gsstepper

dependencies:
  gsstepper: ^0.0.4

Usage

Import the package into your Dart code:

import 'package:gsstepper/gsstepper.dart';

Create a GSStepper widget and pass a list of GSStep widgets to it:

stepper = GSStepper.scrollable(
                currentIndex: currentStep,
                style: StepperStyle(),
                steps: widget.stepperItemList,
                stepperData: GSStepperData(),
                stepWidth: 100,
                onComplete: () {
                  // on complete steps
                },
                onNextStep: (index) {
                  currentStep = index;
                  setState(() {});
                },
              ),
            )

Or you can use this way if you want fixed GSStepper:

stepper = GSStepper.fixed(
                currentIndex: currentStep,
                style: StepperStyle(),
                steps: widget.stepperItemList,
                stepperData: GSStepperData(),
                stepWidth: 100,
                onComplete: () {
                  // on complete steps
                },
                onNextStep: (index) {
                  currentStep = index;
                  setState(() {});
              },
            ),
          )

Customization

To create an instance of GSStepModel, you can pass the following parameters:

• globalKey (required): This is a GlobalKey used to identify the step.
• icon (optional): An Icon widget representing the icon for the step.
• status (optional): An enum value of GSStepStatusEnum representing the status of the step. It has a default value of inActive.
• progress (optional): An integer representing the progress of the step.
• stepName (optional): A string representing the name or description of the step.
• stepNumber (optional): A string representing the step number.

Here's an example of how to create an instance of GSStepModel:

List<GSStepModel> stepperItemList = [
  GSStepModel(
    globalKey: GlobalKey(),
    icon: const Icon(Icons.store,
      color: Colors.white,
      size: 12,
    ),
    status: GSStepStatusEnum.inActive,
    progress: 0,
    stepName: 'User Information Step',
    stepNumber: 'Step 1',
  ),
  // Add more GSStepModel objects here...
];

Conclusion

GSSTEPPER provides a simple and customizable way to create a step-by-step process in your Flutter application. It can be used for user onboarding, form submission, or any other multi-step tasks.
