Migrating to v0.2.6

Fluxy v0.2.6 introduces Industrial Log Professionalization and Experimental Guardrails. This guide will help you migrate from v0.2.5 to v0.2.6.

Breaking Changes

1. Professional Logging System

The emoji-based logging system has been replaced with semantic bracketed tags for better readability and professional debugging.

2. Experimental Feature Guardrails

OTA, SDUI, and Cloud CLI features are now clearly marked as experimental with warnings.

Migration Steps

Step 1: Update Core Package

Update your pubspec.yaml:

dependencies:
  fluxy: ^0.2.6

Step 2: Update Log Monitoring

If you were monitoring specific emoji-based logs, update your log parsing:

// Before (v0.2.5)
// [KERNEL] Stability Kernel initialized
// [SYS] Package system ready
// [CAMERA] Camera module loaded

// After (v0.2.6)
// [KERNEL] [INIT] Stability Kernel initialized
// [SYS] [READY] Package system ready
// [CAMERA] [READY] Camera module loaded

Step 3: Update Experimental Feature Usage

If you're using experimental features, be aware of new warnings:

// Experimental features now show warnings
// [EXPERIMENTAL] OTA updates are in beta - use with caution
// [EXPERIMENTAL] SDUI renderer is experimental - API may change
// [EXPERIMENTAL] Cloud CLI is experimental - not production ready

Step 4: Run Flutter Pub Get

flutter pub get

Log System Changes

Before (v0.2.5)

// Emoji-based logs
// [KERNEL] Auto-repair applied to layout violation
// [SYS] Plugin registry initialized
// [CAMERA] Camera capture completed
// [AUTH] Authentication successful
// [NETWORK] HTTP request completed

After (v0.2.6)

// Semantic bracketed tags
[KERNEL] [REPAIR] Auto-repair applied to layout violation
[SYS] [INIT] Plugin registry initialized
[CAMERA] [READY] Camera capture completed
[AUTH] [AUDIT] Authentication successful
[NETWORK] [DATA] HTTP request completed

New Log Tag System

System Components

• [KERNEL] - Core stability kernel operations
• [SYS] - System-level operations
• [DATA] - Data operations and persistence
• [IO] - Input/output operations

Log Levels

• [INIT] - Initialization and startup
• [READY] - Component ready state
• [AUDIT] - Important operations and state changes
• [REPAIR] - Auto-repair operations
• [FATAL] - Critical errors
• [PANIC] - System-level emergencies

Experimental Features

• [EXPERIMENTAL] - Experimental feature usage warnings

Experimental Guardrails

OTA (Over-the-Air) Updates

// New warning when using OTA
[EXPERIMENTAL] OTA updates are in beta - use with caution
[EXPERIMENTAL] FluxyRemote sync lifecycle may change
[EXPERIMENTAL] Remote manifest parsing is experimental

SDUI (Server-Driven UI)

// New warning when using SDUI
[EXPERIMENTAL] SDUI renderer is experimental - API may change
[EXPERIMENTAL] JSON schema parsing is experimental
[EXPERIMENTAL] Dynamic styling is experimental

Cloud CLI

// New warning when using Cloud CLI
[EXPERIMENTAL] Cloud CLI is experimental - not production ready
[EXPERIMENTAL] CI/CD scaffolding is experimental
[EXPERIMENTAL] GitHub Actions generation is experimental

Testing Your Migration

1. Check Log Output

Run your app and verify logs appear with new format:

// Look for logs like this:
[KERNEL] [INIT] Fluxy initialized
[SYS] [READY] Plugin engine ready
[DATA] [AUDIT] State hydrated

2. Test Experimental Features

If using experimental features, verify warnings appear:

// Check for experimental warnings
[EXPERIMENTAL] Feature is experimental - use with caution

3. Verify Log Monitoring

Update any log monitoring systems to parse new format:

// Update regex patterns
// Old: /\[(KERNEL|SYS|CAMERA|AUTH|NETWORK)\]/
// New: /\[(KERNEL|SYS|DATA|IO)\]/

🆘 Common Issues

Issue: Missing Emoji Logs

Problem: Logs don't show emojis anymore Solution: This is intentional - update log monitoring to use semantic tags

Issue: Experimental Warnings

Problem: Seeing new experimental warnings Solution: These are intentional warnings - no action needed unless you want to avoid experimental features

Issue: Log Parsing Failures

Problem: Log monitoring tools can't parse new format Solution: Update parsing regex to match new bracketed tag format

Benefits of Migration

1. Professional Logging

• Better Readability: Clear semantic tags instead of emojis
• Standardized Levels: Consistent severity indicators
• ASCII Compatibility: Works better with log analysis tools
• Searchable: Easier to filter and search logs

2. Experimental Guardrails

• Clear Warnings: Know when you're using experimental features
• API Stability: Understand which features may change
• Production Safety: Avoid experimental features in production
• Better Documentation: Clear experimental status

3. Improved Debugging

• Categorization: Clear component categorization
• Severity Levels: Standardized log levels
• Diagnostic Clarity: Better error tracking and debugging
