This is function for get data from redis server and put it into flutter app.

import 'package:resp_client/resp_client.dart';
import 'package:resp_client/resp_commands.dart';

void getData(key) async {
  final server = await connectSocket('localhost');
  final client = RespClient(server);
  final commands = RespCommands(client);
  final get = await commands.get('test');
  return get;
}

import 'package:resp_client/resp_client.dart';
import 'package:resp_client/resp_commands.dart';

Future<void> getData(key) async {
  final server = await connectSocket('localhost');
  final client = RespClient(server);
  final commands = RespCommands(client);
  final get = await commands.get('test');
  return get;
}
