## What it is
Drift is a reactive, type-safe persistence library for Dart and Flutter built on top of SQLite. It supports writing queries in both SQL and a fluent Dart API, with compile-time checked queries and auto-updating result streams.

## Use cases
- persist structured data in a Flutter app with SQLite
- watch database queries as reactive streams that update the UI
- write type-safe SQL queries checked at compile time in Dart
- manage schema migrations for a local mobile database
- run database work across isolates for better performance
- build a cross-platform app with local storage on Android, iOS, desktop and web

## When to choose
- you need relational data with joins, transactions, and complex SQL in a Flutter or Dart app
- you want compile-time safety for queries instead of parsing raw maps
- you need reactive UI updates driven by database changes
- you need a battle-tested, production-ready local database layer across all Flutter platforms

## When to avoid
- you only need simple key-value storage with no relational queries
- your project is not Dart or Flutter based
- you need a server-side or cloud-hosted database rather than local persistence

## Facets
- artifact type: library
