NitroWebPorts class final

Registry mapping integer port ids to message handlers — the web analog of the VM's native-port table.

On native, generated code hands ReceivePort.sendPort.nativePort to C, which posts via Dart_PostCObject_DL. On web, C posts through a function-table callback carrying the same int64 port id; the module load path decodes the payload and calls deliver. Pure Dart — unit-testable without a WASM module.

Static Methods

allocate(void handler(dynamic raw)) → int

Registers handler and returns its port id.

close(int port) → void

Closes a port. Posts to a closed port are dropped, mirroring Dart_PostCObject on a closed native port.

deliver(int port, dynamic raw) → bool

Delivers a decoded message to port's handler. Returns false when the port is closed (message dropped).
