What is the TextEditingController?
Answer
TextEditingController is used to read, write, and listen to changes in a TextField. Assign it to the controller property of the TextField. Read the current text with controller.text, set text with controller.text = "new value", and listen for changes by adding a listener: controller.addListener(() { ... }). Always call controller.dispose() in the widget's dispose() method to free resources and prevent memory leaks.
