flutter_state_migrator 2.3.3

Automated CLI tool to migrate Flutter apps from Provider, BLoC, GetX, and MobX to Riverpod.

🚀 Flutter Architecture Intelligence Platform

The Flutter Architecture Intelligence Platform is a production-grade suite designed to help teams modernize, analyze, and govern large-scale Flutter codebases.

Evolved from the Flutter State Migrator, this platform goes beyond simple code rewriting to provide deep semantic understanding, architecture health metrics, and automated governance.

---

✨ Key Capabilities

• Semantic Architecture Analysis: Uses AST-based scanning to build a comprehensive dependency graph of your application.
• Multi-Framework Migration: Automates the transition from Provider, BLoC/Cubit, GetX, and MobX to modern Riverpod with @riverpod annotations.
• Architecture Health Scoring: Real-time scoring (0-100) based on detected architecture smells like God Components, State Explosion, and High Coupling.
• Automated Governance: Enforce scalable development practices by defining forbidden layer dependencies and complexity limits.
• Verification Matrix: Golden-style regression fixtures validate scanner, transformer, visualization, and integration behavior across supported frameworks.
• Safety-First Transformation: Integrated snapshot and manifest-based rollback systems ensure every aggressive rewrite is reversible.
• Interactive Dashboard: Review architecture health, governance posture, migration rollout, and Mermaid relationship diagrams from one place.
• IDE Intelligence: Structured diagnostics and quick-fix recommendations surface architecture warnings inline in the optional VS Code companion extension.
• AI Guidance with Safe Fallbacks: --ai prefers a local Ollama endpoint for migration recommendations and falls back to deterministic architecture guidance when the model is unavailable.
• Monorepo & Workspace Intelligence: Automatically detects and validates architecture across multi-package Flutter ecosystems.

🚀 Quick Start

Installation

Install the platform CLI globally via pub.dev:

dart pub global activate flutter_state_migrator

Note: The package is published as flutter_state_migrator, providing the migrator CLI command.

Usage

Run the intelligence engine on your project directory:

# Analyze architecture and detect smells
migrator .

# Preview migration changes (Dry Run)
migrator --mode aggressive --dry-run .

# Apply migration and governance fixes
migrator --mode aggressive .

# Generate a visual architecture relationship graph
migrator --visualize .

# Emit IDE diagnostics as JSON for editor integrations
migrator --ide-json .

# Print AI-assisted guidance using a local Ollama model when available
migrator --ai .

---

⚖️ Architecture Governance

Define your architecture contracts in migrator_config.yaml:

# Governance Rules
governance:
  forbidden_imports:
    - presentation -> data
    - ui -> repository
  feature:
    max_dependencies: 8

# Naming Conventions
provider_naming: camelCase
