## What it is
Equatable is a Dart package that implements value-based equality for your classes, overriding == and hashCode automatically so you don't have to write boilerplate. It requires no code generation and works across all Dart and Flutter platforms.

## Use cases
- compare dart objects by value instead of identity
- avoid overriding == and hashCode manually
- make flutter state classes comparable in tests
- use value objects in sets and maps correctly
- reduce boilerplate in bloc state classes
- implement deep equality for complex class properties

## When to choose
- you write Dart or Flutter code and need value equality without codegen
- you use bloc or similar patterns where state comparison matters
- you want a lightweight, zero-dependency-heavy equality solution

## When to avoid
- you prefer code-generation approaches like freezed or built_value
- you need equality semantics beyond property-based comparison
- you're not working in Dart or Flutter

## Facets
- artifact type: library
- maturity: stable
- function: serialization
- domain: developer-tools, cross-platform, mobile-development
- platform: cross-platform
- tags: equality, hashcode, value-objects, flutter, dart-package, boilerplate-reduction
