Kalender: A Calendar package in the spirit of Flutter
summary
Kalender is an open‑source Flutter calendar that renders month/week/day/schedule views, supports drag/drop via Draggable/DragTarget with four tile states, and powers an interactive time‑tracking app used in Trinket. Event storage changes from a list to events controller uses two maps cut CPU lookups dramatically for decades of imported data, and a GitHub Actions matrix runs tests across time zones to catch DST bugs. Layout uses MultiChildLayoutDelegate for vertical timeline placement and the package is functional but still evolving.
