Flutter is a powerful UI toolkit that allows developers to create beautiful applications for various platforms. One common scenario you might encounter while building Flutter applications is the need to display a dynamic list consisting of other dynamic lists. This might seem daunting at first, especially when mixing widgets like ListView nested within another ListView. However, by following some simple approaches, you can achieve this effectively.

The Problem

Here’s a common version of that code that exhibits the issue:

When you run this code, you might find that the contents of the inner ListView are not displayed. This can be frustrating, but don’t worry, there’s a simple solution!

The Solution

The main issue arises from how the ListView automatically sizes its children. To solve this problem, you need to adjust the shrinkWrap property in your nested ListView.

1. Add the shrinkWrap Property

When you embed ListView within another ListView, you should set the shrinkWrap property to true for the inner ListView. This tells Flutter to size this ListView according to its children rather than trying to take the maximum available space.

Example Code with Adjustment

Here’s how you can adapt the inner ListView:

2. Run the Application

Once you make this adjustment, the inner lists will display correctly when you run the application. You can now make use of dynamic lists efficiently!

Conclusion

Try implementing this in your Flutter applications, and you'll see how seamless it is to manipulate and display lists!
