Flutter AI components by Stream

This repository holds stream_chat_flutter_ai — a standalone set of Flutter components for building LLM-driven chat experiences: streaming text, animated typing indicators, syntax-highlighted code blocks, charts, a purpose-built AI composer, and speech-to-text input.

The package has no dependency on stream_chat, stream_chat_flutter, or any other Stream Chat package — every widget operates on plain strings, callbacks, and controllers, so it can be dropped into any Flutter app or paired with any backend/LLM provider. Wiring it up to a Stream Chat channel is documented as an optional integration.

Packages

Package	Pub	Description
stream_chat_flutter_ai		AI chat UI components: StreamingMessageView, ChatComposer, AITypingIndicatorView, ChartView, CodeBlockView and more.

See the package README for the full component reference.

Getting Started

Add the package to your app:

dependencies:
  stream_chat_flutter_ai: ^0.1.0

Then render a streaming AI response:

import 'package:stream_chat_flutter_ai/stream_chat_flutter_ai.dart';

StreamingMessageView(
  text: markdownText, // updated in real time as chunks arrive
  typingSpeed: const Duration(milliseconds: 10),
);

There is a runnable showcase app in packages/stream_chat_flutter_ai/example — it needs no API key.

Repository layout

This is a Melos monorepo built on Dart pub workspaces, so there is a single shared dependency resolution and one pubspec.lock at the root.

dart pub global activate melos   # requires Dart >= 3.9
melos bootstrap                  # resolves the workspace
melos run analyze                # dart analyze --fatal-infos across the workspace
melos run format                 # dart format --set-exit-if-changed
melos run test:all               # flutter test --coverage
melos run update:goldens         # regenerate golden files
