I was playing around with the digital ink recognition part of the example app and noticed that the scores of every RecognitionCandidate
returned was null.
for (final candidate in state.data) {
debugPrint(
'$LearningDigitalInkRecognition: _startRecognition : text=${candidate.text} : score=${candidate.score}');
}
