Answer 1

Only StatefulWidget hold state . Lifecyle of it is as follow

• createState () : When we build a new StatefulWidget, this one calls createState() right away and this override method must exist
• initState() :it is the first method called after the Widget is created.This is our equivalent to onCreate() and viewDidLoad()
• didChangeDependencies() : This method is called immediately after initState() on the first time the widget is built
• build() : called right after didChangeDependencies(). All the GUI is render here and will be called every single time the UI needs to be render
• didUpdateWidget() : it’ll be called once the parent Widget did a change and needs to redraw the UI
• deactivate() : framework calls this method whenever it removes this State object from the tree
• dispose() :is called when this object and its State is removed from the tree permanently and will never build again.

AppLifecycleState are as follows

• inactive - The application is in an inactive state and is not receiving user input. iOS only

• paused - The application is not currently visible to the user, not responding to user input, and running in the background.

• resumed - The application is visible and responding to user input.

• suspending - The application will be suspended momentarily. Android only
