How to Use Init State and SetState in Flutter | A Beginner's Guide | Spire View Tech | Flutter Class

1.initState(): This method is called when the stateful widget is inserted into the widget tree for the first time. It's typically used for initialization tasks that need to be performed once, such as setting up variables, initializing controllers, or subscribing to streams. It's important to call super.initState() within this method to ensure that the parent class's initState method is also executed.
2. setState(): This method is used to notify Flutter that the internal state of a stateful widget has changed, and that the UI needs to be rebuilt. When you call setState(), Flutter schedules a build for the widget and its descendants, allowing you to update the UI based on the new state. It's important to only call setState() when the state actually changes, as unnecessarily calling it can lead to performance issues.
Summary: "initState()" is called once when the widget is first created, and "setState()" is used to update the UI in response to changes in the widget's state. Together, these methods help manage the lifecycle and state of stateful widgets in Flutter.
