Reusing Your Flutter Card Widget with Dynamic Images and Text

When building applications with Flutter, efficiency and clean code structure become increasingly important. One common challenge developers face is how to reuse widgets, especially when they contain varying content, like images and text.

In this guide, we will discuss how to tackle the problem of needing multiple images for a card widget without resorting to copy and paste. Instead, we'll learn how to create a reusable Card widget where we can dynamically change the content.

The Problem

Imagine you have a card widget that displays an image along with a title and secondary text. Each time you want to create a new card with different images or text, you might be tempted to duplicate your widget code. This not only leads to redundancy but also makes your code harder to maintain.

Here is the initial code:

As you can see from the code above, the OwnCard class defines a specific image and text. If you want to create another card with a different image and text, you would need to create another instance of the OwnCard and provide a new image asset and hardcoded text. This is inefficient and not ideal.

The Solution

To avoid redundancy, we can modify the OwnCard class so it accepts parameters for the image path, title, and secondary text. This way, you can create as many cards as needed with differing content while still using the same widget code.

Step-by-Step Implementation

Add Parameters:
We will add imagePath, title, and secondaryText as required parameters in the OwnCard constructor.

Update the Build Method:
Modify the build method to use the parameters instead of hardcoded values.

Using the Modified Widget

Now, when you want to create a card, you simply need to provide the different images and text as parameters.

Conclusion

By modifying the OwnCard widget to accept parameters, you gain the ability to create versatile, reusable components in Flutter without duplicating code. This method not only optimizes your codebase but also significantly boosts maintainability.
