Sending Data Between Pages in Flutter: A Step-by-Step Guide

Passing data between pages in Flutter can often be a daunting task for new developers. If you're working with Flutter and you want to send data from one page to another, you've come to the right place! In this guide, I will walk you through the steps required to send and display a list of data from the first page to the second page.

The Problem

You may find yourself in a situation where you've made a list of items on the first page. You want to tap on one of these items and see more details on a second page, but you’re unsure how to pass that specific item's data. Let’s take a look at a common scenario.

Example Scenario

You have a list of courses displayed on the first page, and when a user taps on a course card, you want to show detailed information about that particular course on the second page. If you’re having trouble doing this, don’t worry; we’ll solve it together!

The Solution

Step 1: Modify the onTap Method

In your first page, you’ll need to update the onTap method to pass the relevant data to the second page. Here’s how you can do it:

Step 2: Update the Second Page

Next, you need to modify the second page (MyCourseDetails) to accept the parameters you are passing. Instead of using a generic variable, we will define specific variables for each piece of information:

Step 3: Build the User Interface

Once you’ve set up the parameters in MyCourseDetails, you can now utilize them to create an engaging user interface. For instance, you can display the course title, lecture number, and duration clearly on the screen.

Conclusion

By following these steps, you will be able to transition data smoothly between pages in your Flutter application. Ensuring that you have a structured approach will help you organize your code better and make it more maintainable.

Don’t hesitate to explore and modify the passing mechanism as per your app's requirements. Happy coding!
