fullScreen static method
Sets the app to full-screen mode (no buttons, bars, or notifications on top).
This method makes the app immersive, hiding the system UI elements. For example, the navigation bar and system status bar.
Example:
await EaseDevice.fullScreen();
Implementation
static Future<void> fullScreen() {
return SystemChrome.setEnabledSystemUIMode(SystemUiMode.immersiveSticky);
}
