search method

void search(
  1. String value
)

Waits for a short pause in typing so each keystroke doesn't re-search every body; clearing applies at once.

Implementation

void search(String value) {
  _debounceTimer?.cancel();
  final needle = value.trim().isEmpty ? '' : value.toLowerCase();
  if (needle.isEmpty) {
    _apply('');
  } else {
    _debounceTimer = Timer(_debounce, () => _apply(needle));
  }
}
