toString method
override
Depending on the values of isPending and isSuccess, returns a string to represent the DriverTestMessage.
Used as an alternative method to converting the object to json since
RequestData is only accepting string as message
.
Implementation
@override
String toString() {
if (isPending) {
return 'pending';
} else if (isSuccess) {
return 'complete';
} else {
return 'error';
}
}
