Flutter UI error when retracting keyboard

I could help you better if you posted a code sample of what you did, but try these few steps, and I hope they work!

1 - you should set "resizeToAvoidBottomInset" to "false" for the main scaffold widget.
it will ignore any auto-resize proccesses.

2 - use "KeyboardDismissHandler" as main wrapper for scaffold body.
its a widget that helps manage keyboard dismissal in a more controlled way.
its not built-in so you must use a library named "keyboard_dismiss_handler".
its good for preventing lags and ui issues.

3 - Sometimes using animations make smoother appear/disappear proccess and it removes lags and ui-show issues. not guaranteed but good to check.

for last tip, you could use Custom Keyboard-Aware Widget.
let me show you an example :

class KeyboardAwareView extends StatefulWidget {
  final Widget child;
  
  const KeyboardAwareView({Key? key, required this.child}) : super(key: key);
  
  @override
  _KeyboardAwareViewState createState() => _KeyboardAwareViewState();
}

class _KeyboardAwareViewState extends State<KeyboardAwareView> {
  double _keyboardHeight = 0;
  
  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) {
      _setupKeyboardListeners();
    });
  }
  
  void _setupKeyboardListeners() {
    // Listen for keyboard changes
  }
  
  @override
  Widget build(BuildContext context) {
    return AnimatedContainer(
      duration: const Duration(milliseconds: 300),
      padding: EdgeInsets.only(bottom: _keyboardHeight),
      child: widget.child,
    );
  }
}

// Use like this:
Scaffold(
  resizeToAvoidBottomInset: false,
  body: KeyboardAwareView(
    child: SingleChildScrollView(
      child: YourContentWidget(),
    ),
  ),
)
