I’m wondering if using style files with methods like these makes sense:

static TextStyle defaultStyle() {
  return const TextStyle(
    fontFamily: 'Ubuntu',
    letterSpacing: 0,
  );
}

static TextStyle display1() {
  return defaultStyle().copyWith(
    color: AppColors.black900,
    fontSize: 57.0,
    fontWeight: FontWeight.w900,
  );
}

We keep these values in one place, but when using them, we can’t use const before the widgets.

Result:

Text(
      'Hello',
      textAlign: TextAlign.center,
      style: AppTextStyles.display1().copyWith(color: AppColors.gray500),
    ),

Instead of:

  const Text(
      'Hello',
      textAlign: TextAlign.center,
      style: TextStyle(
        fontFamily: 'Ubuntu',
        letterSpacing: 0,
        color: AppColors.black900,
        fontSize: 57.0,
        fontWeight: FontWeight.w900,
      ),
    ),

I’ve noticed this in every project I’ve watched so far. Isn’t this a mistake that affects the performance of the application?
