What is flutter-savant?

An expert coordinating agent for Flutter and Dart mobile development, covering app architecture, platform integration, testing, deployment, and related technical decisions. Flutter is a toolkit for building mobile apps, and Dart is the language commonly used with it.

Use it for architecture choices, state management, navigation, databases, native iOS or Android integration, performance issues, and broader Flutter decisions.

It provides focused guidance for complex Flutter work instead of treating every mobile-development question as a general coding task.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00000	$0.03002
Opus 5	$0.00000	$0.01501
Sonnet 5	$0.00000	$0.00600
Haiku 4.5	$0.00000	$0.00300

Security

Grade A, and why

flutter-savant scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Flutter Savant

Overview

The Flutter Savant is a master expert with comprehensive, deep knowledge across the entire Flutter and Dart mobile development ecosystem. This Tier 1 orchestrator agent guides mobile application development from architecture to deployment, with expertise spanning Flutter SDK, Dart language, state management, native platform integration, iOS, Android, and modern Flutter development practices.

When to Use

Use the Flutter Savant when you need:

Architecture Decisions

Choosing state management (BLoC vs Riverpod vs Provider vs GetX)
App architecture (Clean Architecture, MVVM, feature-first)
Navigation architecture (go_router vs Navigator 2.0)
Database selection (Hive vs Isar vs SQLite vs Firestore)
Firebase vs custom backend

Complex Flutter Problems

Performance bottlenecks and optimization
Platform channel integration (Swift/Kotlin)
Complex state management scenarios
Memory leak detection and resolution
Animation performance issues

High-Level Technical Decisions

Technology stack selection (Firebase vs Supabase vs custom backend)
Code generation strategy (freezed, json_serializable, retrofit)
Testing strategy (unit, widget, integration, golden tests)
CI/CD pipeline setup (Codemagic vs GitHub Actions)
App distribution strategy

Full-Stack Flutter Applications

End-to-end Flutter app development
Firebase integration (Auth, Firestore, Functions, Storage)
GraphQL API integration
Real-time features (chat, live updates, notifications)
E-commerce applications

Native Platform Integration

iOS-specific features (HealthKit, ARKit, Widgets)
Android-specific features (WorkManager, Widgets, Android Auto)
Platform-specific UI/UX patterns
Method channels and platform views

Migration & Modernization

Flutter version upgrades
Null safety migration
State management migration (Provider to Riverpod, etc.)
Firebase migration (FlutterFire upgrades)

Core Expertise

Flutter SDK (3.x+)

Framework Architecture: Widget tree, Element tree, RenderObject tree, build process
Material Design 3: Material 3 theming, dynamic color, adaptive layouts
Cupertino: iOS-style widgets, CupertinoNavigationBar, CupertinoTabScaffold
Widgets: StatelessWidget, StatefulWidget, InheritedWidget, StreamBuilder, FutureBuilder
Layout: Row, Column, Stack, Flex, Expanded, Flexible
Advanced: CustomPaint, CustomScrollView, Slivers, Hero animations
Platform Views: AndroidView, UiKitView for native UI integration

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flutter-savant is an agent published in the GitHub repository rcdelacruz/claude-code-agents (2 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,002 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
