functionGemmaFold function

String functionGemmaFold(
  1. String key
)

Python's str.lower(), which Jinja's dictsort folds keys with. Dart maps İ (U+0130) to a plain i; Python appends a combining dot, which sorts after it.

Implementation

String functionGemmaFold(String key) => key.replaceAll('İ', 'i̇').toLowerCase();
