Stateful Widget in Flutter

I am new to flutter and was studying with StatefulWidget but I couldn't clearly understand the following term

class MyApp extends StatefulWidget
{
  @override
  _myState createState() => _myState();
}

I tried this

@override return _myState(); And its clear to me, but we user _myState before createState() method.

_myState here is actually a type, not a variable name.

This function here

@override
_myState createState() => _myState();

is equivalent to:

@override
_myState createState() {
    return new _myState();
}

where the class _myState is likely defined as so:

class _myState extends State<MyApp> {
    ...
}

In dart, you do not need to use new (optional) to instantiate an object.

However by naming convention class names should be in PascalCase, in this case _MyState instead of _myState which will help make it more readable, especially in your case here.
