One common challenge developers face is how to create a Text widget that can accept parameters like font size, color, and weight at the time of calling the function. This not only saves time but also promotes cleaner code. In this blog, we’ll guide you through creating a custom Text widget class in Flutter-Dart, which makes your UI more adaptable and maintains consistency across your application. The Problem You might encounter a situation where your Text widget needs a specific font size when used in a button interface. Instead of hardcoding the font size and color, you prefer to call a function or a widget that allows for these parameters to be set dynamically. For instance, the following snippet shows a simple approach where the font size is not specified.

The Solution: Creating a Custom Text Widget To address this problem, we’ll define a class called CustomText. This class will inherit from StatelessWidget and will include parameters for text, font size, color, and weight. Here’s how you can build it: Step 1: Setting Up the Class Define a class named CustomText that extends StatelessWidget. You will also need to import material.dart to access Material Design features.

The text parameter will be required while the others will be optional, allowing flexibility. [[See Video to Reveal this Text or Code Snippet]] Step 3: Implementing the Build Method The build method is where we will create the Text widget using the parameters defined earlier. We can use Dart’s null-aware operator to provide default values for the optional properties.

This not only helps in keeping the code DRY (Don’t Repeat Yourself) but also enhances maintainability as your project grows. Next time you need a Text widget with specific styles, remember that you can easily adapt your design to make it dynamic and reusable. Happy coding!
