LibserialportSerialTransport class

Implemented types

• SerialTransport

Constructors

LibserialportSerialTransport({DynamicLibrary? library, String? libraryPath, Duration pollInterval = const Duration(milliseconds: 5), int readBufferSize = 1024})

LibserialportSerialTransport.withBindings(LibserialportBindings _bindings, {Duration pollInterval = const Duration(milliseconds: 5), int readBufferSize = 1024})

Construct from an already-instantiated bindings instance — useful for tests that mock the FFI surface.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

incoming → Stream<Uint8List>

Stream of incoming byte chunks. Each event is a chunk exactly as received from the OS read buffer (no re-chunking).

no setter, override

isOpen → bool

no setter

pollInterval → Duration

final

readBufferSize → int

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

close() → Future<void>

Close the port.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

open(String portName, SerialConfig config) → Future<void>

Opens the underlying port using config. Idempotent.

override

readModemStatus() → Future<ModemStatus>

Read the current state of the four DCE→DTE modem-status lines. Production transports query the underlying driver (sp_get_signals for libserialport, GetCommModemStatus for Windows). The default throws so existing custom transports keep compiling; override to expose this capability.

override

sendBreak({Duration duration = const Duration(milliseconds: 250)}) → Future<void>

Send a BREAK condition for duration.

override

setDtr(bool active) → Future<void>

Drive the DTR (Data Terminal Ready) modem control line. Default implementation throws — production transports override.

override

setRts(bool active) → Future<void>

Drive the RTS (Request To Send) modem control line.

override

toString() → String

A string representation of this object.

inherited

write(List<int> bytes) → Future<void>

Transmit a raw byte sequence.

override

Operators

operator ==(Object other) → bool

The equality operator.
