toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse
function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString
to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
return "Buad rate : $_baudRate, Data bits : ${dataBitToString()}, Stop bits : ${stopBitsToString()}, Parity : ${parityToString()}, Flow control : ${flowControlToString()}, RTS : ${_rts.toString()}, DTR : ${_dtr.toString()} ";
}
