If you’re looking to add engaging tutorials to your application, the TutorialCoachMark package makes it beautifully simple. Whether you want to walk your users through the app’s features or highlight critical functions, this package serves as an excellent companion. This guide will lead you through the setup and usage of TutorialCoachMark, making your application not just functional, but phenomenally user-friendly!

Step 1: Add Dependency

First, you need to include the TutorialCoachMark package in your project. Open your pubspec.yaml file and add the package as a dependency:

dependencies:
  tutorial_coach_mark: ^latest_version

Replace ^latest_version with the latest version available on pub.dev.

Step 2: Code Your Tutorial

Incorporate the TutorialCoachMark by initializing it in your Dart code. Below is a simple analogy to help you understand the code structure better:

An Analogy for TutorialCoachMark

Imagine you’re a tour guide leading a group through a museum. Each exhibit (or target) you stop at has a sign (tutorial content) that describes what it is. Just like the exhibits, your app has features (like buttons or sections) that users need to understand. The TutorialCoachMark guides them from one feature to another, highlighting each with the appropriate information.

Example Code

Here’s how you can create a tutorial that resembles introducing exhibits in a museum:

import 'package:flutter/material.dart';
import 'package:tutorial_coach_mark/tutorial_coach_mark.dart';

List targets = [];

// Define a function to show your tutorial
void showTutorial(BuildContext context) {
  TutorialCoachMark tutorial = TutorialCoachMark(
    targets: targets,
    colorShadow: Colors.red,
    alignSkip: Alignment.bottomRight,
    textSkip: "SKIP",
    paddingFocus: 10,
    onFinish: () => print("Finished!"),
    onClickTarget: (target) => print("Clicked: $target"),
  )..show(context: context);
}

// Populate targets
void initState() {
  targets.add(
    TargetFocus(
      identify: "Target 1",
      keyTarget: keyButton, // This is the button widget
      contents: [
        TargetContent(
          align: ContentAlign.bottom,
          child: Text("Welcome to Feature 1!"),
        ),
      ],
    ),
  );

  // Add more targets here
}

This code represents how you would define and show a tutorial that walks users through different features of your app, focusing on one at a time just like a tour guide explaining one exhibit before moving on to the next.

Troubleshooting

In case of any issues while implementing the TutorialCoachMark, here are some troubleshooting instructions:

• Problem: Targets not showing
  • Ensure that the keyTarget provided corresponds to an actual widget in your layout.
  • Check if the show(context: context) method is being called correctly.
• Problem: Tutorial doesn’t advance to the next target
  • Verify that you have properly set up the onClick events for navigating through the targets.
