renderableSearchText function

String renderableSearchText(
  1. RenderableMessage msg
)

Flatten a RenderableMessage to lowercased searchable text.

Cached -- messages are append-only and immutable so a hit is always valid. Lowercased at cache time.

Implementation

String renderableSearchText(RenderableMessage msg) {
  final cached = _searchTextCache[msg];
  if (cached != null) return cached;
  final result = _computeSearchText(msg).toLowerCase();
  _searchTextCache[msg] = result;
  return result;
}
