## What it is
Flutter is Google's open-source UI SDK for building natively compiled applications for mobile, web, and desktop from a single Dart codebase. It provides a rich widget catalog, pixel-level rendering control via Skia/Impeller, and hot reload for fast development.

## Use cases
- build an ios and android app from one codebase
- create a cross-platform desktop application
- build a mobile app with material design
- develop a progressive web app with dart
- ship a beautiful ui without writing platform-specific code
- prototype mobile apps quickly with hot reload

## When to choose
- you want one codebase targeting mobile, web, and desktop
- you need highly custom, pixel-perfect ui and animations
- your team prefers dart and a batteries-included widget set
- you want fast iteration with hot reload

## When to avoid
- you need deep native platform integration or platform-specific look via native controls
- your team is invested in react native or native swift/kotlin ecosystems
- you need very small app binaries or minimal startup overhead
- you are building a content-heavy seo-critical website
