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() => 'TotalView[confidence=$confidence, costCents=$costCents, provider=$provider, requests=$requests, scope=$scope, source_=$source_, tokens=$tokens, usedPct=$usedPct, window=$window, windows=$windows]';
