Overview
The background_app_bar package is a Flutter plugin designed to maintain the background appearance of a SliverAppBar during scrolling. It ensures that the visual background—such as an image or gradient—remains visible and consistent as users scroll, enhancing the visual continuity of the app interface. Ideal for apps with rich, immersive designs, it works across multiple platforms including Android, iOS, Web, macOS, Windows, and Linux. The plugin integrates seamlessly with existing SliverAppBar implementations without requiring major code changes.
