Overview
The nearby_connections package provides Flutter integration with Android's Nearby Connections API, enabling peer-to-peer communication between devices over Bluetooth, Wi-Fi, and NFC. It supports the transfer of both raw bytes and files, making it ideal for local data sharing in proximity-based applications. The plugin is lightweight and designed specifically for Android, leveraging native capabilities for reliable, low-latency connections. It’s useful for collaborative apps, multiplayer games, or file-sharing tools that require direct device-to-device interaction without internet dependency.
