## What it is
Flash Calendar is a fast, lightweight React Native calendar library built on Flash List, supporting date ranges, infinite scroll, localization, and dark mode. It is Expo-compatible with a tiny bundle size (~18kb minified).

## Use cases
- build a calendar in react native
- date range picker for mobile app
- expo compatible calendar component
- localized calendar with infinite scroll
- lightweight calendar with dark mode support
- calendar with bottom sheet integration

## When to choose
- you need a performant calendar in React Native or Expo
- you want date range selection and localization out of the box
- bundle size and minimal dependencies matter

## When to avoid
- you need a web (DOM) calendar rather than React Native
- you need heavy out-of-the-box features like event scheduling or agenda views
- your project doesn't use Flash List as a peer dependency
