Creating a Scrolling Widget Inside a Non-Scrollable Container in Flutter Web

Are you a Flutter developer trying to create a responsive web page that features a scrolling widget alongside a fixed-size container? This is a common requirement in apps where elements like contact lists can scroll independently while other parts of the page remain fixed, similar to the WhatsApp Web interface. In this guide, we'll guide you through the process of achieving this effect using Flutter Web SDK.

Understanding the Problem

In many user interfaces, especially when dealing with contacts or chat lists, the need arises for one part of the screen to scroll while another part remains static. For instance, on WhatsApp Web, you can scroll through your contacts without losing sight of the chat.

If you're developing a similar layout in Flutter and you're wondering how to implement it with a constant size container while having a scrollable widget, this guide is for you.

The Solution Breakdown

Step 1: Setup Your Layout

To accomplish this layout, you will utilize the Row and Container widgets. Here’s a basic overview of how to structure your code:

Parent Row: The main layout holder that will contain both your scrollable and non-scrollable containers.

Non-scrollable Container: This will hold content that doesn't require scrolling. You may want to give it a defined height or width to ensure that it maintains its size.

Scrollable Container: This will contain a SingleChildScrollView, allowing you to scroll through its contents. The dimensions of this container can be adjusted based on your requirements.

Step 2: Implementing the Code

Here's a sample code snippet that demonstrates how to set up this layout:

Step 3: Making It Responsive

To ensure that the layout is responsive across different screen sizes, you'll want to utilize MediaQuery. This Flutter feature allows you to query the size of the device and create a responsive design that adapts to various screen dimensions.

Tips for Customization

Adjust Dimensions: Feel free to modify the width and height of your containers based on your layout needs. Experiment with different sizes to see what works best for your application.

Scroll Direction: You can customize the scroll direction of the SingleChildScrollView according to your design requirements.

Conclusion

Implementing a scrolling widget next to a fixed-size container in Flutter Web is straightforward with the right approach. By utilizing a combination of Rows and Containers, along with a scrollable widget, you can create a layout that allows for smooth user interactions.

Now, you should be well-equipped to create that responsive design that leaves your users satisfied. Happy coding!
