detectedLanguageConfidences property
Structured per-language detection results: confidence, document share, script,
and reliability, alongside the ISO-code-only detected_languages (#261).
One entry per language in detected_languages, in the same order. None under
the same conditions as detected_languages: detection disabled, empty input
text, or no language met the configured min_confidence.
Implementation
final List<LanguageConfidence>? detectedLanguageConfidences;
