A Flutter plugin for detecting internet connectivity changes across Android and iOS using Kotlin Multiplatform (KMP).
This plugin exposes a simple cross-platform API to observe network connection changes using Kotlin Flow under the hood — giving you real-time updates about internet availability in a reactive way.
- ✅ Realtime internet connection monitoring
- ✅ Shared logic built using Kotlin Multiplatform (KMP)
- ✅ Android: Uses
ConnectivityManagerandFlow<Boolean> - ✅ iOS: Uses
NWPathMonitorandFlow<Boolean> - ✅ Clean Dart API:
observe()andisConnected() - ✅ No third-party dependencies in Dart
