Step 3: Understanding the Code

In this example, we've defined a CustomTextField class that builds a TextField widget with an IconButton inside the suffixIcon property.

InputDecoration: This parameter allows you to customize the appearance of the TextField.

labelText: Provides a hint text inside the TextField.

IconButton: This widget is used to create an icon that functions as a button.

icon: Specifies the visual appearance of the button.

onPressed: This is a callback function that gets executed when the button is tapped.

Step 4: Adding Functionality to the Icon Button

You can customize the onPressed method inside the IconButton to perform any action you want. For example, you might want to search content based on the input text:

In this updated example, we have added a _search method to log the entered text when the icon is pressed. You can replace the print statement with your custom search logic.
