如何在Flutter中使用Dio或http发送带有GET请求的参数

dependencies:
  dio: ^3.0.0
  http: ^0.13.0

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

void fetchData() async {
  try {
    var dio = Dio();
    var response = await dio.get('https://example.com/api', queryParameters: {'param1': 'value1', 'param2': 'value2'});
    print(response.data);
  } catch (e) {
    print(e.toString());
  }
}

void fetchData() async {
  var url = Uri.parse('https://example.com/api');
  var response = await http.get(url.replace(queryParameters: {'param1': 'value1', 'param2': 'value2'}));
  print(response.body);
}
