How can themes be dynamically changed at runtime in a Flutter app?

Themes can be dynamically changed at runtime in a Flutter app by implementing a state management solution. This typically involves storing the selected theme in a state variable and updating it as needed. When the theme is changed, the UI components can be rebuilt with the updated theme, providing a seamless transition. This approach allows for flexibility and customization, enabling users to switch between different themes while the app is running. Understanding how to implement dynamic theme changes enhances the user experience and adds a layer of personalization to the app.
