Krithiga Perumal focused on stabilizing the Flutter PDF Viewer in the syncfusion-content/flutter-docs repository by addressing a persistent bug affecting the text selection context menu. She improved the widget’s state management by introducing a key to the PdfViewer widget, ensuring reliable identification and consistent UI behavior during text selection. Working primarily with Dart and Flutter, she resolved edge-case interactions that previously led to unstable context menu states, thereby enhancing the reliability of the documentation viewer. Her work emphasized bug fixing and documentation, resulting in a smoother experience for both developers and readers who rely on the Flutter PDF documentation site.
