* Improve scroll performance by introducing repaint boundaries and moving more calculations to providers. * Add error handing for malformed dates. * Remove unused method * Use compute in different places to improve app performance during heavy tasks * Fix test * Refactor `List<RenderAssetGridElement>` to separate `RenderList` class and make `fromAssetGroups` a static method of this class. * Fix loading indicator bug * Use provider directly * `RenderList` refactoring * `AssetNotifier` refactoring * Move `combine` to static private method * Extract compute methods in cache services to static private methods. * Use `tryParse` instead of `parse` with try/catch for dates. * Fix bug in caching mechanism. * Fixed state not being used to trigger conditional rendering * styling * Corrected state Co-authored-by: Alex Tran <alex.tran1502@gmail.com>
