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() {
var str = "WifiRecord: ";
str += "ssid=$ssid ";
str += "authenticationType=$authenticationType ";
str += "encryptionType=$encryptionType ";
if (macAddress != null) {
str += "macAddress=$macAddress ";
}
return str;
}
