• Enable debug mode in ResponsiveAdaptiveManager, update DebugInfoPanel to use the manager instance directly, and refactor device type detection logic for improved performance and clarity. Additionally, enhance the UI of DebugInfoPanel for better responsiveness and usability.

Added #

Changed #

• Breaking Change (Backward Compatible): Replaced hardcoded iPhone dimensions (375x812) with configurable baseline dimensions
  • responsiveWidth() now uses config.baselineScreenWidth instead of hardcoded 375.0
  • responsiveHeight() now uses config.baselineScreenHeight instead of hardcoded 812.0
  • Default configuration maintains original iPhone baseline for backward compatibility

Improved #

• Design System Flexibility: Apps can now choose baselines that match their target platform
• Cross-Platform Optimization: Better scaling results for Android, web, and desktop platforms
• Configuration Architecture: More consistent use of constants throughout the codebase

Performance #

• No Runtime Impact: Baseline values are set at configuration time with no performance penalty
• Maintained Caching: All existing performance optimizations continue to work

Migration #

• Existing Apps: Continue to work without changes (default maintains iPhone baseline)
• Recommended: Update to use platform-appropriate baselines:
  • Android/Material apps: Use ResponsiveConfig.materialDesign()
  • iOS apps: Use ResponsiveConfig.cupertino()
  • Web/Desktop apps: Use ResponsiveConfig.webOptimized()
