RtAppConstants class

Application-wide constants for UI styling, sizing, and configuration.

RtAppConstants implements the singleton pattern and provides centralized access to constants used throughout the application. It uses mixins to organize related constants into logical groups.

Constant categories (via mixins):

Example:

// Access via Utils facade
final padding = Utils.appConstants.commonPadding;
final fontSize = Utils.appConstants.textHeaderFontSize;

// Use in widgets
Container(
  padding: EdgeInsets.all(Utils.appConstants.boxPadding),
  child: Text(
    'Hello',
    style: TextStyle(fontSize: Utils.appConstants.normalFontSize),
  ),
);
