The Engineering Challenge

Problem & Constraints

Flutter standard library lacks native Wi-Fi Direct (P2P) networking protocols and zero-copy binary streaming primitives required for multi-gigabyte file transfers.

The Architectural Solution

Technical Implementation

Engineered custom native Android Platform Channels utilizing Android's WifiP2pManager framework. Integrated high-throughput chunked socket streams protected with AES-256 packet encryption.
