Usage

Digital Ink Recognition

Create an instance of DigitalInkRecognizer

final digitalInkRecognizer = DigitalInkRecognizer();

Process points

List<Offset> points; // an array with the points of the stroke
String modelCode; // BCP-47 Code from https://developers.google.com/ml-kit/vision/digital-ink-recognition/base-models?hl=en#text
final List<RecognitionCandidate> canditates = await digitalInkRecognizer.recognize(points, modelCode);

for (final candidate in candidates) {
  final text = candidate.text;
  final score = candidate.score;
}

Release resources with close()

digitalInkRecognizer.close();

Managing remote models

Create an instance of model manager

final modelManager = DigitalInkRecognizerModelManager();

Check if model is downloaded

final bool response = await modelManager.isModelDownloaded(model);

Download model

final bool response = await modelManager.downloadModel(model);

Delete model

final bool response = await modelManager.deleteModel(model);
