Developer Experience

• Method channel: com.device_monitor/ios
• Platform check: isIOS property
• Plugin version: pluginVersion property
• Clean, type-safe Dart API
• Production-ready code (1,600+ lines)

Known Limitations #

Platform Limitations

• iOS only - No Android, macOS, Windows, Linux, or Web support
• Physical devices recommended - Some features (thermal state) may show limited data on simulators
• iOS version dependent - Some features require specific iOS versions:
  • iOS 11.0+: Basic features
  • iOS 12.0+: Enhanced thread information
  • iOS 13.0+: Metal GPU family support
  • iOS 16.0+: Recommended max working set size

Performance Considerations

• Advanced CPU usage can be computationally expensive when tracking many threads
• Polling frequency should be limited to 1-5 seconds for dynamic metrics
• Thread details collection may impact performance in high-thread-count scenarios
• Static information (CPU/GPU) should be cached, not repeatedly queried

API Limitations

• Temperature readings in ThermalState may not be available on all devices
• Some GPU information may be unavailable on older devices or iOS versions
• Thread names in AdvancedCpuUsage may not always be available
• Core affinity information may be limited or unavailable on some iOS versions

No Special Permissions Required

• Uses standard iOS APIs that don't require user authorization
• No privacy concerns or App Store approval issues
