如何在flutter中登录后立即调用get请求？

dependencies:
  http: ^0.13.3

import 'package:http/http.dart' as http;

Future<void> fetchData() async {
  final response = await http.get(Uri.parse('https://api.example.com/data'));
  if (response.statusCode == 200) {
    // 请求成功，处理响应数据
    print(response.body);
  } else {
    // 请求失败，处理错误
    print('请求失败: ${response.statusCode}');
  }
}

void login() {
  // 登录逻辑
  // ...

  // 登录成功后调用GET请求
  fetchData();
}
