In this tutorial, we will learn how to create a widget with state management using StatefulWidget. The CustomWidget class inherits from StatefulWidget and creates a CustomState state through the createState method. Within this state class, a count variable is managed, and a handleClick method is defined to increment this count value whenever a click event occurs.
The UI of the widget is handled by using a GestureDetector to process click events, and the actual UI is constructed using a Container. Inside the Container, a Text widget displays the current count value. All these processes are defined in the build method.
This example helps understand how to structure a stateful widget and how the UI updates in response to state changes.
Each call to setState changes the state, which triggers a re-rendering of the UI.
This allows the user interface to reflect the latest state.
