In Flutter, which method is typically used to update the UI when the state changes?
- rebuildUI() method
- refreshScreen() method
- setState() method
- updateUI() method
In Flutter, the setState() method is typically used to update the UI when the state changes. When the state of a StatefulWidget changes, calling setState() triggers a rebuild of the widget subtree, updating the UI to reflect the new state. This method ensures that the framework knows that the internal state has changed and should be reflected visually. Understanding how to use setState() is essential for interactive and responsive Flutter applications.
