●open source · published on pub.dev

23 packages, out in the open.

Everything we publish, organized by what it does, linked straight to pub.dev and GitHub. The packages with a story get a full write-up.

6 of these have a full write-up: install steps, the key APIs, a usage example, and (for the four skills) the exact reference map our agents read before they touch code. The rest are here in full - name, what it does, and a straight link to pub.dev and the source.

Architecture

The state and app-foundation layer. utopia_hooks and utopia_cms carry the full write-up; the rest are satellites and companions you would reach for alongside them.

utopia_hooks

Flexible state management for Flutter, inspired by React Hooks - local, global, async, and form state in one model.

pub.dev Read more

utopia_cms

An admin-panel toolkit for Flutter - sortable, filterable CRUD tables and per-row actions over Firebase, Supabase, Hasura, or any GraphQL backend.

pub.dev Read more

utopia_cli

The command line for this stack - scaffolds a Screen · State · View app with its .claude/ layer wired, then describe, doctor, and an MCP server give agents and CI a JSON-first view of the project.

utopia_arch

The hooks foundation folded into a full app skeleton - DI, navigation, error handling, and preferences persistence in one package.

utopia_hooks_riverpod

Lets utopia_hooks and Riverpod run side by side in a codebase that already has both.

utopia_lints

Our recommended lint rule set - the conventions the hooks pattern assumes, enforced by the analyzer.

utopia_widgets

Small, generic widgets that come up often enough to share instead of rewrite.

utopia_cms_firebase

The Firebase and Firestore backend for utopia_cms - a ready-made delegate over a collection.

utopia_cms_graphql

The generic GraphQL backend for utopia_cms - a service layer for any GraphQL API without a prebuilt delegate.

utopia_cms_hasura

The Hasura backend for utopia_cms - CRUD tables, filters, and many-to-many relationships over Hasura GraphQL.

Infrastructure

Thin, focused wrappers - REST, crash reporting, file saving, and the localization toolchain - built to be swapped in without reshaping the app around them.

utopia_rest

REST API support built on Dio - the networking layer under our services.

utopia_firebase_crashlytics

Firebase Crashlytics setup plus a Reporter implementation, wired in one step.

utopia_reporter

The Reporter architecture on its own - a single interface for logging and crash reporting you can back with any service.

utopia_save_file

A unified, correct implementation of file saving across platforms - the part every app gets subtly wrong once.

utopia_localization_annotationutopia_localization_generatorutopia_localization_utils

Our localization toolchain: annotate strings, generate the code from a Google Sheet, and use the generated output at runtime - three packages, one pipeline.

annotation generator utils GitHub

Utilities

The low-level building blocks: bytes, collections, connectivity, platform checks, generic helpers, and validation. Small on purpose.

utopia_bytes

Byte-level helpers for binary data - encoding, decoding, and the conversions in between.

utopia_collections

Collection utilities that fill the gaps in Dart's standard list, set, and map APIs.

utopia_connectivity

A connectivity state hook - know when the app is online, offline, or in between, without polling by hand.

utopia_platform_utils

Android and iOS platform checks and helpers, in one package instead of scattered Platform.is* calls.

utopia_utils

Generic Dart extensions and utilities, plus the Reporter architecture - our most-used package outside the core stack.

utopia_validation

Generic validation building blocks - the pieces a form or an API boundary checks input against.

AI tooling

The skills our Claude Code agents run on, published under the utopia-flutter-skills marketplace. Not on pub.dev - installed as Claude Code plugins, and the same skills your team keeps after hand-over.

utopia-hooks

The skill our agents follow when they write a Flutter screen - Screen/State/View, the hook catalog, and a quality gate after every edit.

utopia-cms

The skill that stops a Flutter admin panel being hand-rolled - declare your fields, point a delegate at your backend, done.

utopia-ai-arch

The skill that builds and polices the agent system itself - a four-agent roster, enforcement hooks, and a drift catalogue.

utopia-hooks-migrate-bloc

A 5-agent pipeline that takes a BLoC codebase to utopia_hooks screen by screen, behind a hard exit gate.
