sendRequest method

@override Future<Map<String, dynamic>> sendRequest({ required String method, required Map<String, dynamic> params, })

Sends a request to the LSP server and waits for a response. This is used for synchronous operations that require a reply from the server.

Implementation

@override
Future<Map<String, dynamic>> sendRequest({
  required String method,
  required Map<String, dynamic> params,
}) async {
  final id = _nextId++;
  final request = {
    'jsonrpc': '2.0',
    'id': id,
    'method': method,
    'params': params,
  };

  _channel.sink.add(jsonEncode(request));

  return await _responseController.stream.firstWhere((response) {
    return response['id'] == id;
  }, orElse: () => throw TimeoutException('No response for request $id'));
}
