TencentCloudChatState<T extends StatefulWidget> class abstract

An abstract base class for the state of StatefulWidget in TencentCloudChat.instance.

This class extends the Flutter State class and provides a foundation for managing theme data and screen types for the Chat UIKit widgets. It includes methods for handling data changes and selecting appropriate widget builders based on the current platform and screen type.

All widgets in the Chat UIKit should extend this class to ensure a consistent appearance and behavior.
