AppFontSizesConstants class

Compile-time constant font sizes using the default configuration.

This class provides const font size values that can be used in compile-time constant expressions, unlike AppFontSizes which is instantiated at runtime.

All values are calculated using:

  • Base size: 14 pixels
  • Scale factor: 1.27 (large)

When to use:

  • Use AppFontSizesConstants when you need compile-time constants (e.g., in const constructors, default parameter values)
  • Use AppFontSizes when you need runtime flexibility (e.g., dynamic sizing, user preferences)

Example:

// ✅ Good: Compile-time constant
const TextStyle(
  fontSize: AppFontSizesConstants.body,
);

// ✅ Good: Default parameter value
Widget buildText({
  double fontSize = AppFontSizesConstants.body,
}) { ... }

// ❌ Won't work with AppFontSizes (not const)
const TextStyle(
  fontSize: AppFontSizes().body, // Error!
);
