Debugging Guide for REChain

This guide provides tips and tools for debugging issues in REChain.

Debugging Tools

Flutter DevTools

  • Inspect widget tree
  • View performance metrics
  • Debug memory leaks
  • Analyze network requests

Logging

import 'dart:developer';

log('Debug message', name: 'REChain', error: error, stackTrace: stackTrace);

Debugging in IDE

  • Use breakpoints
  • Step through code
  • Inspect variables
  • Evaluate expressions

Common Debugging Techniques

Reproduce the Issue

  • Identify steps to reproduce
  • Isolate minimal test case

Analyze Logs

  • Check console output
  • Look for exceptions and errors
  • Use verbose logging if needed

Use Assertions

assert(value != null, 'Value should not be null');

Debugging Asynchronous Code

  • Use debugPrint for async logs
  • Await futures properly
  • Use FlutterError.onError to catch errors

Hot Reload and Restart

  • Use hot reload for UI changes
  • Use hot restart for state resets

Debugging Network Issues

Inspect HTTP Requests

  • Use tools like Charles Proxy, Wireshark
  • Log request and response data

Handle Timeouts and Errors

  • Implement retry logic
  • Show user-friendly error messages

Debugging Database Issues

Verify Queries

  • Log SQL queries
  • Use database clients to inspect data

Handle Migrations

  • Check migration scripts
  • Test migrations in staging

Debugging UI Issues

Layout Problems

  • Use Flutter Inspector
  • Check widget constraints and sizes

Animation Issues

  • Profile animations
  • Check for dropped frames

Debugging State Management

State Inspection

  • Use state management devtools (e.g., Provider, Bloc)

Debugging Streams

  • Log stream events
  • Check for memory leaks

Debugging Tips

  • Keep code simple and modular
  • Write reproducible tests
  • Collaborate with team members
  • Document debugging steps
