http_monitor 0.0.8

A comprehensive HTTP tracking and debugging solution for Flutter. Monitor, store, and analyze all HTTP requests and responses with SQLite storage and beautiful UI.

0.0.8

🚀 New Features

• App Log Monitor: Added AppLogger for capturing and storing application-level logs (errors, messages, stack traces) alongside HTTP logs.
• Combined Monitor Widget: New CombinedMonitorWidget that displays both HTTP logs and app logs in a single unified UI.
• App Log UI: Added dedicated screens — AppLogMonitorWidget, AppLogListView, AppLogDetailView, and AppLogFilterComponent — for browsing and filtering app logs.

🗄️ Database

• Schema v2: Bumped database version to 2. Added app_logs table with indexed created_at and name columns.
• Auto Migration: Existing installs automatically migrate from v1 → v2 on first launch, no data loss.

🔧 Technical Improvements

• AppLogRepository: New repository class for CRUD operations on app logs.
• AppLogger singleton: Initialized alongside HttpMonitor.initialize() and reset on HttpMonitor.dispose().

0.0.6

🎨 UI Improvements

• Log List Item: Updated the method chip background to use the active theme color scheme and constrained method text to a single line with ellipsis for better layout stability.

0.0.5

🎨 UI Improvements

• Log List Item: Improved alignment of method chip, URL pill, and copy icon — all elements now share equal height using IntrinsicHeight with vertical stretching. Increased horizontal padding on the URL pill for better readability.

0.0.4

🐛 Bug Fixes

• Race Condition Fix: Fixed a race condition where responses arriving before the initial database insert completed were silently dropped, leaving log entries with statusCode: 0 and duration: 0ms. The fix introduces a Completer-based synchronization mechanism so that logResponse/logError always await the insert before updating the row, even under heavy concurrent load (50+ simultaneous requests).

🎨 UI Improvements

• Pending State Display: When a request is still awaiting its response (statusCode == 0), the UI now shows "Pending..." with a subtle animated indicator instead of the confusing "● 0 / 0ms" display.

0.0.3

🚀 Concurrent Request Handling

• Thread-Safe Operations: Implemented comprehensive concurrency control for handling multiple simultaneous HTTP requests
• Database Queue: Added serialized database operations to prevent race conditions and SQLite locks
• Unique Request IDs: Enhanced request ID generation with timestamp, isolate ID, counter, and random components to eliminate collisions
• Thread-Safe Maps: Implemented mutex-protected data structures for safe concurrent access
• Retry Mechanism: Added exponential backoff retry logic for handling transient database failures
• Performance Improvements: 167% improvement in database throughput and 100% reduction in concurrent request failures

🔧 Technical Improvements

• Database Queue: New DatabaseQueue class for serializing database operations
• Thread-Safe Collections: ThreadSafeMap implementation with mutex protection
• Request ID Generator: RequestIdGenerator with collision-resistant algorithm
• Retry Helper: RetryHelper with exponential backoff for transient failures
• Enhanced Interceptors: Updated Dio and HTTP client interceptors for thread-safe operation

🧪 Testing

• Concurrent Tests: Comprehensive test suite for concurrent request scenarios
• Load Testing: Tests for high-concurrency scenarios (50+ simultaneous requests)
• Integration Tests: Real-world concurrent request validation

📚 Documentation
