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() {
final preview = answer.length > 50 ? answer.substring(0, 50) : answer;
return 'RAGResult(answer: "$preview...", chunks: ${retrievedChunks.length}, '
'totalTimeMs: $totalTimeMs)';
}
