The $1 Unistroke Recognizer, a 2D single-stroke recognizer. This is a Dart port of the original JavaScript implementation.

0.4.1 #

  • Fixed images on pub.dev.
  • Added a RecognizedUnistroke.convertToOval() method.

0.4.0 #

  • This release has changed the default set of templates to contain better shapes. The old templates are still available in example$1Unistrokes. The new templates are only a circle, rectangle, and triangle, where the old templates were more varied but were also sketched by hand and were not very pretty.
  • Inputs are now recognized even if they are drawn in the opposite direction of the template. For example, a clockwise circle will be recognized as a circle, even if the template is a counter-clockwise circle. This wasn't the case in previous releases.
  • Like previous releases, convertToCanonicalPolygon() is still returning incorrectly rotated shapes. See https://github.com/adil192/one_dollar_unistroke_recognizer/issues/2 to track progress on this issue.

0.3.1 #

  • Scores can now only be between 0 and 1. Would-be negative scores are interpreted to mean that the stroke is not recognized, so null is returned.

0.3.0 #

  • Added functions to RecognizedUnistroke to get a "perfect" shape from the user's stroke: see RecognizedUnistroke.convertToCanonicalPolygon and RecognizedUnistroke.convertToCircle.

0.2.0 #

  • Recognize custom unistrokes by setting the referenceUnistrokes variable, or by passing the overrideReferenceUnistrokes parameter to recognizeUnistroke.

0.1.1 #

0.1.0 #

  • Initial release.
  • TODO: Allow adding custom unistrokes.
