## What it is
dartx is a Dart package providing a collection of useful static extension methods for core types like Iterable, String, int, Map, DateTime, and functions. It adds Kotlin-style conveniences such as slice, sortedBy, distinctBy, flatten, and chunkWhile to Dart and Flutter projects.

## Use cases
- slice and manipulate lists with negative indices in dart
- sort a list of objects by multiple properties in flutter
- get distinct elements from a list by a key in dart
- flatten nested lists in dart
- chunk a list while a predicate matches
- add null-safe string helpers like isNullOrBlank to dart
- kotlin-style collection extensions for dart

## When to avoid
- you prefer minimal dependencies and only need one or two trivial helpers
- your project already standardizes on package:collection and wants to avoid overlapping extension names
- you need actively evolving features — the package is stable but releases are infrequent

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools
- domain: developer-tools, cross-platform
- platform: cross-platform
- tags: dart, flutter, static-extensions, collections, strings, utility-library
