writeJsonAsync method

@override Future<void> writeJsonAsync(StringSink sink, JsonEncoderCallback encode)

Writes the JSON representation of this object directly to the sink. Use encode to safely serialize any nested child objects.

Implementation

@override
Future<void> writeJsonAsync(
  StringSink sink,
  JsonEncoderCallback encode,
) async {
  sink.write('"');
  await for (final chunk in stream) {
    // jsonEncode escapes the chunk and adds surrounding quotes (e.g., "chunk\ntext").
    final escaped = jsonEncode(chunk);
    if (escaped.length >= 2) {
      // Strip the first and last character to extract just the escaped inner content
      sink.write(escaped.substring(1, escaped.length - 1));
    }
  }
  sink.write('"');
}
