Platform Channel

Definitions

1. A Flutter mechanism for bidirectional communication between Dart code and native platform code (Swift/Kotlin/Java/Objective-C), using asynchronous message passing over named channels with a standardized codec for serializing method calls and responses.

   In plain English: A bridge in Flutter apps that lets the cross-platform Dart code talk to native iOS or Android code when it needs to use a phone-specific feature.

   Example: "We used a platform channel to call the native biometric API from Dart since there's no pure-Flutter fingerprint scanner package."
