I am trying to understand the best style for creating your own widgets in flutter, and here are 2 very simplified examples

With the code at the bottom, I can use 1)

new SomeWidget("Some title", someFunction);

or 2)

SomeWidget.widget("Some title", someFunction);

or 3) Some other way I'm not aware of

Method 1) feels more correct (if I've not made some mistakes), however method 2) actually has less code (as I don't need to declare the object variables earlier, assuming I don't need access to context), but I'm wary of static methods.

Is 1) preferred, and why ?

class SomeWidget extends StatelesssWidget 

 String title;
 Function callback;

 SomeWidget( this.title, this.callback );

 //method 1
 Widget build(context) 
 return GestureDetector(
 onTap: callback,
 child: ....some widget
 )
 

 //method 2
 static Widget widget(String title, Function callback) 
 return GestureDetector(
 onTap: callback,
 child: ....some widget
 )
 

I don't know actual guildelines, but I would prefer something like

class SomeWidget extends StatelesssWidget 

 SomeWidget(this.title, this.callback);

 final String title;
 final VoidCallback callback;

 Widget build(context) 
 return GestureDetector(
 onTap: callback,
 child: ....some widget
 );
 

or you can do like this

SomeWidget(this.title = '', @required this.callback)

for default values or if some value is reqired

P.S. All this is not guideline - it's just an IMHO )
