## What it is
Flutter is Google's open-source UI framework for building natively compiled applications for mobile, web, desktop, and embedded devices from a single Dart codebase. The flutter/plugins repository contains the Flutter team's first-party plugins for accessing platform-specific APIs, though it has been archived and development moved to the flutter/packages repository.

## Use cases
- build ios and android apps from one codebase
- cross-platform mobile app development framework
- access native device apis like camera in flutter
- build desktop and web apps with dart
- find first-party flutter plugins for platform channels

## When to choose
- you want a single codebase targeting mobile, web, and desktop
- you need pixel-perfect custom UI with hot reload productivity
- you want first-party, well-maintained plugins for platform APIs
- you prefer Dart and a widget-based development model

## When to avoid
- you need a tiny app footprint or minimal runtime overhead
- your team is deeply invested in native Swift/Kotlin toolchains
- you need direct access to this archived plugins repo - use flutter/packages instead
- you require heavy platform-specific UI conventions over custom rendering
