How to customize the hard wrap vertical line in Android Studio IDE for code formatting

Question

When I apply "Format code" my lines of code automatically down line (many lines) even though my screen has enough space to display it on 1 line.

I see it depends on the vertical line (red in the image), how can I remove this line or widen it?

My language is: Dart

You can disable the line from File->Settings->Editor->Appearance and then uncheck 'Show hard wrap and visual guides'.

You can take reference from these two images:

'Show hard wrap and visual guides' checked

'Show hard wrap and visual guides' unchecked

Also you can customize it from the 'Code Style' option in the same(Editor) dropdown.

For your reference: Hard wrap with value 50:

Hard wrap with value 100:

Edit: for flutter development you need to the change the line length for auto formatting in dart option in the code style dropdown. Like this:

A lot of customizations could be done according to the need.
