Give your AI agent eyes on your Flutter app.

fdb drives a running Flutter app from the CLI. No MCP needed, works with any bash-capable agent.

@somi_ai @HuyNguyenTw Hooks into the existing Flutter VM service - same one DevTools uses. fdb_helper registers a few VM service extensions on top for things like widget interaction, but the transport is standard.

@justin_vu113 @HuyNguyenTw @jezell Thanks!
Main difference is philosophy - Marionette added CLI as a fallback, fdb was CLI from day one. No MCP, no protocol overhead, just bash. Also handles app launch so the agent never touches VM URIs, plus deep links, SharedPreferences, and waiting for widgets/routes.

[Andrzej Chmielewski @andrzejchm]

@itstarun1994 @HuyNguyenTw Yes! The agent takes a screenshot to see the coordinates, then taps with fdb tap --at x,y. Just tell your agent: "Fetch and follow instructions from https://t.co/50DYMhBImY" and it sets itself up and figures out the rest.

[Andrzej Chmielewski @andrzejchm]

@Michael08079961 @HuyNguyenTw Works with both today! Both support the Agent Skills standard natively - just feed this to your agent and it'll handle the rest: https://t.co/6yLkXHJwQu

[Andrzej Chmielewski @andrzejchm]

Works with Claude Code, OpenCode, or any agent that can run shell commands.

Install with:
dart pub global activate fdb

▸ trigger deep links
▸ read/write SharedPreferences
▸ wait for widgets & routes
▸ stream filtered logs
▸ pre-flight health checks (fdb doctor)

[Andrzej Chmielewski @andrzejchm]

Your agent calls fdb describe → gets a structured widget tree back.

No vision model needed to navigate the UI. No MCP server to configure. Just bash.

[Andrzej Chmielewski @andrzejchm]

What fdb can do:

▸ inspect widget tree & describe UI
▸ screenshot (iOS, Android, macOS, Linux)
▸ tap, double-tap, long press
▸ scroll, scroll-to, swipe
▸ input text, navigate back

@TurkishAirlines @TurkishAirlines you lost our luggage on 29 Dec.
6 days later: only generic call-center replies, no updates, no timeline, no interim support.
Is this normal for you?

Exciting moment! The #Flutter app I architected and led the team on at Picnic is now open-sourced on GitHub. It follows best practices of Clean Code, Clean Architecture & MVP pattern using BLoC and solid CI/CD setup. Proud moment! #OpenSource #PicnicApp

@MateuszBrat "sometimes" was used in a context that it's simply SOMETIMES faster and most of the time its on par with the performance. Using metal under the hood is not an extra block, cause the same block of "extra" is added when developing in native by using swift/kotlin code

[Andrzej Chmielewski @andrzejchm]

@MateuszBrat it only proves someone chose either a bad cross platform technology (FB using html5 which was a disaster and completely not optimized for robust mobile usage). or had simply bad developers delivering the requirements.

@saltedge thanks for the clarification and prompt responses, appreciated!

[Andrzej Chmielewski @andrzejchm]

@saltedge looks like only wholesale banking integration is in place, while retail customer banking is not

@Matic20701417 @Viberate_com well, I got in pretty easly, was enough to track the blocks count on their website and set higher gas price
