研究方向
Investigate the library's source code, specifically the MaterialViewPagerIndicator and ViewPagerHeader classes, to understand how header visibility and parallax effects are implemented. Check the behavior when setting headerAlpha to 0 and hideToolbarAndTitle to false. The provided GIF suggests a possible bug in the parallax calculation or layout update. Consider replicating the issue with a minimal project and examining the onPageScrolled method. Since the issue is old and no maintainer has responded, it may be necessary to open a new issue with a clear reproduction or search for similar resolved issues.
