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 'type:$type,timestamp:$timestamp,heartrate:$heartrate,swimtime:$swimtime,strokes:$strokes,swimtype:$swimtype,avgstrokefreq:$avgstrokefreq,maxstrokefreq:$maxstrokefreq,swolf:$swolf,avgpace:$avgpace,lapindex:$lapindex';
}
