searchSymbolsStreamer method

  1. @override
Stream<String> searchSymbolsStreamer(
  1. String query
)
override

Search for symbols matching query. Called once per debounced keystroke — the chart takes only the stream's first emission, so a single result (or an empty "[]") is enough; no need to keep pushing updates for the same query.

Same JSON shape as optionSymbols (array of symbol objects).

Implementation

@override
Stream<String> searchSymbolsStreamer(String query) =>
    _symbolSearchChannel.receiveBroadcastStream(query).cast<String>();
