  • large - Prominent loading indicator

​
HuxLoadingOverlay

Full-screen overlay for blocking user interaction during loading.

HuxLoadingOverlay(
  isLoading: _isLoading,
  message: 'Processing...',
  child: YourContent(),
)

​
Properties

  • isLoading - Whether to show the loading overlay

Usage Example

class AsyncOperationExample extends StatefulWidget {
  @override
  _AsyncOperationExampleState createState() => _AsyncOperationExampleState();
}

class _AsyncOperationExampleState extends State<AsyncOperationExample> {
  bool _isLoading = false;

  void _performAsyncOperation() async {
    setState(() {
      _isLoading = true;
    });

    // Simulate async work
    await Future.delayed(Duration(seconds: 3));

    setState(() {
      _isLoading = false;
    });
  }

  @override
  Widget build(BuildContext context) {
    return HuxLoadingOverlay(
      isLoading: _isLoading,
      message: 'Loading data...',
      child: Column(
        children: [
          HuxButton(
            onPressed: _isLoading ? null : _performAsyncOperation,
            isLoading: _isLoading,
            child: Text('Start Operation'),
          ),
        ],
      ),
    );
  }
}
