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 s = '$_description' ' $_precipitation' ' $_obscuration' ' $_other';
s = s.replaceAll('null', '');
s = s.replaceAll(RegExp(r'\s{2,}'), ' ');
return s.trim();
}
