Decoupling Designs: Material, Cupertino, and You in the Post-SDK Split Era

With Flutter's recent architectural shift, Material and Cupertino widgets have been separated into standalone packages, marking a significant change in how we approach theming and design consistency across platforms. This session delves into:

Understanding the SDK Split: What does the decoupling of Material and Cupertino mean for developers?

Implementing Adaptive Themes: Strategies for creating themes that respond to platform differences while maintaining a unified codebase.

Leveraging Custom Themes: Building and integrating custom themes that cater to specific design requirements and user preferences.

Best Practices and Pitfalls: Common challenges in theming post-split and how to navigate them effectively.
