Describe the problem

Seems like old or wrong documentation

class TextStyles {
static const TextStyle raleway = TextStyle(
fontFamily: Fonts.raleway,
);
static TextStyle buttonText1 =
const TextStyle(fontWeight: FontWeight.bold, fontSize: 14);
static TextStyle buttonText2 =
const TextStyle(fontWeight: FontWeight.normal, fontSize: 11);
static TextStyle h1 =
const TextStyle(fontWeight: FontWeight.bold, fontSize: 22);
static TextStyle h2 =
const TextStyle(fontWeight: FontWeight.bold, fontSize: 16);
static TextStyle body1 = raleway.copyWith(color: const Color(0xFF42A5F5));
// etc
}

Expected fix

copyWith is not available for TextStyle

static TextStyle buttonText1 =
const TextStyle(fontWeight: FontWeight.bold, fontSize: 14);

constructor being called is not a const constructor.

Additional context

No response

I would like to fix this problem.

• I will try and fix this problem on docs.flutter.dev.

OK, this page should have been removed when the adaptive responsive docs were rewritten. Removing it now.
