During January 2025, contributed to the Tencent/tdesign-flutter repository by addressing a platform-specific UI issue affecting HarmonyOS. Focused on Flutter development using Dart, implemented a targeted fix to improve text alignment centering, ensuring consistent vertical alignment of text components in build v3.22. This work involved analyzing platform rendering differences and adjusting layout calculations to resolve user-reported visual defects. The solution enhanced cross-platform UI consistency and improved the user experience for HarmonyOS users. Demonstrated attention to detail in both Flutter layout management and Git-based change tracking, resulting in a more stable release and reducing visual inconsistencies across supported platforms.
