## What it is
Flyer Chat is an open-source, backend-agnostic chat UI package for Flutter, providing a high-performance and highly customizable chat interface widget. It supports real-time messengers, AI agents, and LLM-based assistants across iOS, Android, Web, macOS, Windows, and Linux.

## Use cases
- add a chat interface to a flutter app
- build a real-time messaging ui in flutter
- create a chat ui for an llm-based ai assistant
- build a customer support chat screen
- customize chat message bubbles and themes in flutter
- render different chat message types in a flutter app

## When to choose
- you need a polished, performant chat UI in Flutter without building it from scratch
- you want a backend-agnostic chat interface you can connect to any service
- you need cross-platform chat support including web and desktop
- you want modular, customizable chat components with theming and builders

## When to avoid
- you need a full chat backend with auth, storage, and sync - this is UI only
- you are building with React Native and need stable docs (still work in progress)
- you need a non-Flutter/Dart solution
