The daylight package provides accurate sunrise and sunset times for any given geolocation using only local calculations, eliminating the need for external APIs. It leverages precise astronomical algorithms to compute these times based on latitude and longitude, ensuring reliable results across different platforms. Ideal for apps that require time-based features tied to daylight, such as scheduling, reminders, or ambient lighting adjustments. The package is lightweight, cross-platform, and open-source, making it easy to integrate into Flutter projects.
