Buoy for Flutter (Beta)

Buoy now works in Flutter apps. The network inspector ships first — the same three surfaces you get on React Native:

1. In your app — a floating devtools bubble with the network panel.
2. On your desktop — live traffic in the Buoy Desktop Network panel, side by side with your React Native devices.
3. In your AI editor — the Buoy MCP server can read your Flutter app's traffic (get_snapshot with toolId: "network").

More tools are coming from the React Native suite one by one — vote for what's next.

Install

flutter pub add buoy

flutter pub add buoy

Or just the network tool: flutter pub add buoy_network.

Wire it up

One widget — wrap your app via MaterialApp.builder:

import 'package:buoy/buoy.dart';

MaterialApp(
  builder: (context, child) => BuoyDevTools(
    deviceName: 'My App',
    child: child ?? const SizedBox.shrink(),
  ),
)

import 'package:buoy/buoy.dart';

MaterialApp(
  builder: (context, child) => BuoyDevTools(
    deviceName: 'My App',
    child: child ?? const SizedBox.shrink(),
  ),
)

That's the whole setup. Every installed Buoy tool self-registers on mount: HTTP capture (HttpOverrides), the floating in-app menu, the live desktop connection, and the MCP server. Optional props: licenseKey for Pro, socketUrl for physical devices, deviceId to pin the device identity, and tools for your own custom tools.

Devices

• iOS Simulator / Android Emulator — connects to Buoy Desktop automatically (localhost / 10.0.2.2).
• Physical devices — pass your computer's LAN IP via the widget: BuoyDevTools(socketUrl: 'http://192.168.1.x:42831', …). iOS will show the Local Network permission prompt on first connect — tap Allow.

What gets captured

Everything riding dart:io's HttpClient in one hook — no per-client setup:

Known gaps (by design, documented): cupertino_http / cronet_http native clients, gRPC (raw sockets), secondary isolates, Flutter web.

Beta notes

• Package versions are 0.x — APIs may shift between minor versions.
• The React Native suite's other tools (console, storage, state inspectors…) are being ported — the roadmap decides the order.
• Source is visible on GitHub. Proprietary license — free in development, Pro unlocks production and MCP, same as React Native.
