⚠️ Security & Production Guidelines

🚨 IMPORTANT: ISpect is a debugging tool and should NEVER be included in production builds

🔒 Production Safety

ISpect contains sensitive debugging information and should only be used in development and staging environments. To ensure ISpect is completely removed from production builds, use the following approach:

✅ Recommended Setup with Dart Define Constants

1. Create environment-aware initialization:

// main.dart
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';

// Use dart define to control ISpect inclusion
const bool kEnableISpect = bool.fromEnvironment('ENABLE_ISPECT', defaultValue: false);

void main() {
  if (kEnableISpect) {
    // Initialize ISpect only in development/staging
    _initializeISpect();
  } else {
    // Production initialization without ISpect
    runApp(MyApp());
  }
}

void _initializeISpect() {
  // ISpect initialization code here
  // This entire function will be tree-shaken in production
}

2. Build Commands:

# Development build (includes ISpect)
flutter run --dart-define=ENABLE_ISPECT=true

# Staging build (includes ISpect)
flutter build appbundle --dart-define=ENABLE_ISPECT=true

# Production build (ISpect completely removed via tree-shaking)
flutter build appbundle --dart-define=ENABLE_ISPECT=false
# or simply:
flutter build appbundle  # defaults to false

3. Conditional Widget Wrapping:

Widget build(BuildContext context) {
  return MaterialApp(
    // Conditionally add ISpectBuilder in MaterialApp builder
    builder: (context, child) {
      if (kEnableISpect) {
        return ISpectBuilder(child: child ?? const SizedBox.shrink());
      }
      return child ?? const SizedBox.shrink();
    },
    home: Scaffold(/* your app content */),
  );
}

🛡️ Security Benefits

• ✅ Zero Production Footprint: Tree-shaking removes all ISpect code from release builds
• ✅ No Sensitive Data Exposure: Debug information never reaches production users
• ✅ Performance Optimized: No debugging overhead in production
• ✅ Compliance Ready: Meets security requirements for app store releases

🔍 Verification

To verify ISpect is not included in your production build:

# Build release APK and check size difference
flutter build apk --dart-define=ENABLE_ISPECT=false --release
flutter build apk --dart-define=ENABLE_ISPECT=true --release

# Use flutter tools to analyze bundle
flutter analyze --dart-define=ENABLE_ISPECT=false

🚀 Quick Start

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:ispect/ispect.dart';

// Use dart define to control ISpect inclusion
const bool kEnableISpect = bool.fromEnvironment('ENABLE_ISPECT', defaultValue: false);

void main() {
  if (kEnableISpect) {
    // Initialize ISpect only in development/staging
    _initializeISpect();
  } else {
    // Production initialization without ISpect
    runApp(MyApp());
  }
}

void _initializeISpect() {
  // Initialize ISpectify for logging
  final ISpectify logger = ISpectifyFlutter.init();

  // Wrap your app with ISpect
  ISpect.run(
    () => runApp(MyApp()),
    logger: logger,
  );
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: kEnableISpect
          ? ISpectLocalizations.localizationDelegates([
              // Add your localization delegates here
            ])
          : [
              // Your regular localization delegates
            ],
      // Conditionally add ISpectBuilder in MaterialApp builder
      builder: (context, child) {
        if (kEnableISpect) {
          return ISpectBuilder(child: child ?? const SizedBox.shrink());
        }
        return child ?? const SizedBox.shrink();
      },
      home: Scaffold(
        appBar: AppBar(title: const Text('ISpect Example')),
        body: Center(
          child: ElevatedButton(
            onPressed: () {
              if (kEnableISpect) {
                ISpect.logger.info('Button pressed!');
              }
            },
            child: const Text('Press me'),
          ),
        ),
      ),
    );
  }
}

⚙️ Advanced Configuration

🛡️ Environment-Based Setup

// Create a dedicated ISpect configuration file
// lib/config/ispect_config.dart

import 'package:flutter/foundation.dart';

class ISpectConfig {
  static const bool isEnabled = bool.fromEnvironment(
    'ENABLE_ISPECT',
    defaultValue: kDebugMode, // Only enable in debug by default
  );
  
  static const String environment = String.fromEnvironment(
    'ENVIRONMENT',
    defaultValue: 'development',
  );
  
  // Only enable in development and staging
  static bool get shouldInitialize => 
    isEnabled && (environment != 'production');
}

🎨 Custom Theming (Development Only)

// Wrap theming configuration in conditional check
Widget build(BuildContext context) {
  return MaterialApp(
    builder: (context, child) {
      if (ISpectConfig.shouldInitialize) {
        return ISpectBuilder(
          theme: ISpectTheme(
            pageTitle: 'Debug Panel',
            lightBackgroundColor: Colors.white,
            darkBackgroundColor: Colors.black,
            lightDividerColor: Colors.grey.shade300,
            darkDividerColor: Colors.grey.shade800,
            logColors: {
              'error': Colors.red,
              'info': Colors.blue,
            },
            logIcons: {
              'error': Icons.error,
              'info': Icons.info,
            },
            logDescriptions: [
              LogDescription(
                key: 'riverpod-add',
                isDisabled: true,
              ),
              LogDescription(
                key: 'riverpod-update',
                isDisabled: true,
              ),
              LogDescription(
                key: 'riverpod-dispose',
                isDisabled: true,
              ),
              LogDescription(
                key: 'riverpod-fail',
                isDisabled: true,
              ),
            ],
          ),
          child: child ?? const SizedBox.shrink(),
        );
      }
      return child ?? const SizedBox.shrink();
    },
    home: Scaffold(/* your app content */),
  );
}

🎛️ Panel Customization (Development Only)

Widget build(BuildContext context) {
  return MaterialApp(
    builder: (context, child) {
      if (!ISpectConfig.shouldInitialize) {
        return child ?? const SizedBox.shrink(); // Return app without ISpect in production
      }
      
      return ISpectBuilder(
        options: ISpectOptions(
          locale: const Locale('en'),
          isFeedbackEnabled: true,
          actionItems: [
            ISpectActionItem(
                onTap: (BuildContext context) {
                  // Development-only actions
                },
                title: 'Dev Action',
                icon: Icons.build),
          ],
          panelItems: [
            ISpectPanelItem(
              enableBadge: false,
              icon: Icons.settings,
              onTap: (context) {
                // Handle settings tap
              },
            ),
          ],
          panelButtons: [
            ISpectPanelButtonItem(
                icon: Icons.info,
                label: 'Debug Info',
                onTap: (context) {
                  // Handle debug info tap
                }),
          ],
        ),
        child: child ?? const SizedBox.shrink(),
      );
    },
    home: Scaffold(/* your app content */),
  );
}
