Description:

flutter nearby connections

flutter_nearby_connections #
flutter nearby connections
Plugin: https://pub.dev/packages/flutter_nearby_connections
Flutter plugin supports peer-to-peer connectivity and discovers nearby devices for Android and IOS #
The flutter_nearby_connections plugin supports the discovery of services provided by nearby devices.
Moreover, the flutter_nearby_connections plugin also supports communicating with those services through message-based data, streaming data, and resources (such as files). The framework uses infrastructure Wi-Fi networks, peer-to-peer Wi-Fi and Bluetooth Personal Area Networks (PAN) for the underlying transport over UDP.
The project is based on
Android
Nearby Connections API (Bluetooth & hotspot) Support Strategy: Strategy.P2P_CLUSTER, Strategy.P2P_STAR, Strategy.P2P_POINT_TO_POINT
Wi-Fi P2P (only wifi hotspot no internet) Support Strategy: Strategy.Wi_Fi_P2P
IOS
Multipeer Connectivity
We use the NearbyConnections API, but Flutter methods are based on the concept of Multipeer Connectivity IOS.
Methods provided:
startAdvertisingPeer, startBrowsingForPeers, stopAdvertisingPeer
We separate the dependencies of the MCNearbyServiceAdvertiser, MCNearbyServiceBrowser and MCSession classes. All of the methods will be implemented in the NearbyService class.

Android doesn't support emulator only support real devices


On iOS 14, need to define in Info.plist


<key>NSBonjourServices</key>
<array>
<string>_{YOUR_SERVICE_TYPE}._tcp</string>
</array>
<key>UIRequiresPersistentWiFi</key>
<true/>
<key>NSBluetoothAlwaysUsageDescription</key>
<string>{YOUR_DESCRIPTION}</string>
copied to clipboard
in this case, YOUR_SERVICE_TYPE is 'mp-connection' (you can define it)
nearbyService.init(
serviceType: 'mp-connection',
strategy: Strategy.P2P_CLUSTER,
