decode method

@override Future<List<FutoSwipeCandidate>> decode(Iterable<FutoSwipePoint> trace, { FutoSwipeLayout? layout, Iterable<String>? previousWords, int maxCandidates = 3, })

Ranks lexicon words for a swipe trace.

previousWords are the preceding words, oldest first; ContextLM reads the last 16. Null disables ContextLM. An empty list scores the word as the start of text. Each configuration uses its matching bundle weights.

Implementation

@override
Future<List<FutoSwipeCandidate>> decode(
  Iterable<FutoSwipePoint> trace, {
  FutoSwipeLayout? layout,
  Iterable<String>? previousWords,
  int maxCandidates = 3,
}) {
  _ensureOpen();
  final points = validatedFutoTrace(trace);
  final words = previousWords == null
      ? null
      : validatedFutoWords(previousWords, 'previousWords');
  final count = validatedFutoCount(maxCandidates, 'maxCandidates');
  final keys = layout ?? FutoSwipeLayout.englishQwerty();
  return _enqueue(() => _manager.decode(points, keys, words, count));
