研究方向

To implement this feature, first locate the TabBarItem component in the repository (likely in the main tab component file, e.g., 'index.js' or 'lib/TabBarItem.js'). Add a new 'badge' prop to the component's prop types. Then, conditionally render a badge element (such as a small circle with a number) near the tab icon. Reference React Native's TabBarIOS badge implementation for UI guidance. Ensure the badge style is consistent with the existing component. No existing PRs or comments provide further direction, so this is a clean feature addition.
