최신 버전으로 하시고 계신다면 문서를 확인해야 하는데요.

https://pub.dev/packages/http

버전업이 되면서 사용방법이 변경되어서 Uri.parse( ) 로 URL을 감싸줘야 합니다.

var response = await http.get(Uri.parse('https://api.airvisual.com/v2/nearest_city?key=05dad879-fd62-46f1-bdcd-7f4e022f6b1f'));

로 하시면 됩니다.

    AirResult result = AirResult.fromJson(json.decode(response.body));

  });
}

HandshakeException: Handshake error in client (OS Error:

에러가 뜸닙니다.

  test('http 통신 테스트', () async {
    HttpOverrides.global = MyHttpOverrides();

    var response = await get(Uri.parse(
        'https://api.iqair.com/v2/nearest_city?key=b41f3555-5530-428c-84b7-da354eb5170c'));

    expect(response.statusCode, 200);

    AirResult result = AirResult.fromJson(json.decode(response.body));
    expect(result.status, 'success');
  });
}

class MyHttpOverrides extends HttpOverrides{
  @override
  HttpClient createHttpClient(SecurityContext? context) {
    return super.createHttpClient(context)
      ..badCertificateCallback = (X509Certificate cert, String host, int port)=> true;
  }
}
