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
String toString() {
return "\nuserData: ${userData.toString()}\nsessionId: ${sessionId}\nactivityType: ${activityType}\nstartTime: ${startTime}\nendTime: ${endTime}\ntotalTime: ${totalTime}\nexercises: ${exercises}";
}
