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() => 'Answer[cold=$cold, completions=$completions, diagnostics=$diagnostics, hover=$hover, lang=$lang, locations=$locations, op=$op, path=$path, repo=$repo, rev=$rev, symbols=$symbols]';
