How do you retrieve the current value from a TextField widget in Flutter?

To retrieve the current value from a 'TextField' widget in Flutter, you can access the 'text' property of the 'controller' associated with the 'TextField'. Using 'textField.controller.text' allows you to obtain the entered text dynamically. This approach is useful for capturing user input and processing it within your Flutter application. Understanding the role of controllers in handling text input is key to effective Flutter development.
