Const keyword performance improvement in reference to Text Theme

Question

When I am using Text widget, there are two ways from which I can change style of widget

1. Passing TextStyle to style permeter.
2. Passing Theme.of(context).textTheme.titleLarge to style permeter.

when using first method I can use const keyword in front of Text widget and in second cannot. does using first method give me performance boost ?

I know using second method my code will be more organised. Which method should I use ?

Text("Select a City",style: Theme.of(context).textTheme.titleLarge,),

const Text("Select a City",style: TextStyle(fontSize: 22, color:Colors.grey)),

Thanks

1. const makes that widget not to be rebuild when you call setState or otherwise, it can help you increase performance.

2. You should use method 2 because it synchronizes your application, making it easy to change the theme mode
