A high-performance drop-in replacement for Flutter's SliverList and ListView that handles massive lists with variable item sizes and reliable item jumping.
SuperSliverList is a Flutter package that provides high-performance, drop-in replacement widgets for SliverList and ListView. It solves performance issues when scrolling through large lists with variable item sizes and adds reliable item jumping and animation capabilities. It enables developers to handle massive datasets smoothly without compromising on Flutter's standard list APIs.
Flutter developers building applications that display large, scrollable lists with variable-sized items, such as data-heavy mobile apps, dashboards, or content feeds where performance and precise navigation are critical.
Developers choose SuperSliverList because it maintains full compatibility with Flutter's existing list APIs while dramatically improving performance and adding missing features like item jumping. It eliminates the need for complex workarounds or alternative packages that sacrifice integration or functionality.
Drop-in replacement for SliverList and ListView that can handle large (really, really large) amount of items with variable extents and reliably jump / animate to any item.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Handles virtually unlimited items with variable extents without performance degradation, eliminating the need for workarounds like FixedExtentSliverList, as highlighted in the README.
Provides jumpToItem and animateToItem methods that work even for items outside the viewport and not yet built, solving a key limitation in standard SliverList.
Improves scrollbar behavior to be smooth and consistent, addressing erratic jumps common with SliverList when items have different sizes, as noted in the features.
Functions as a direct replacement for SliverList and ListView, working with existing CustomScrollView configurations without API changes, ensuring easy adoption.
Without custom extent estimation or precalculation, scrollbar movement may not be perfectly aligned with list movement, especially on small lists, as admitted in the Advanced section.
Achieving optimal performance and accuracy requires implementing extent estimation callbacks or precalculation policies, adding setup overhead compared to simpler list widgets.
As a newer package, it may lack extensive third-party plugin integration or community resources compared to more established Flutter list solutions, potentially affecting debugging and extensions.
