return_of_invalid_type 返回类型“String”不是“void”，由方法“getData”定义

Question

错误：返回类型“String”不是“void”，由方法“getData”定义。 (return_of_invalid_type at [todo_app_ui] lib/redis.dart:9)

这是从redis服务器获取数据并放入flutter app的函数。

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;
}

Answer 1

它是如何得到修复的！ ：

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;
}
