Flutter:Inconsistently getting error: The getter 'ioRequest' isn't defined for the class 'IOClient'

[Alexander san]

Hi Flutter Community,

This problem appeared to me after implementing a search to the database, previously I had no problem, it worked well for me, but from one moment to another this problem appeared and I do not understand the problem.

/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.12.2/lib/src/io_client.dart:31:9: Error: Expected an identifier, but got '..'. ..followRedirects = request.followRedirects

/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.12.2/lib/src/io_client.dart:36:9: Error: The getter 'ioRequest' isn't defined for the class 'IOClient'. - 'IOClient' is from 'package:http/src/io_client.dart'

('/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.12.2/lib/src/io_client.dart'). Try correcting the name to the name of an existing getter, or defining a getter or field named 'ioRequest'. var response = await stream.pipe(ioRequest) as HttpClientResponse; FAILURE: Build failed with an exception.

Where: Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 904

What went wrong: Execution failed for task ':app:compileFlutterBuildDebug'.

String mensaje = ""; String urldata="https://example/api/data.php"; 

 Future<List> cargarCitas(String usuarioId, String mascotaId) async {

  var usuario = usuarioId; 

  var mascota =mascotaId; 

  var preguntaData = "4"; 

  final respuestacitas = await http.post(Uri.encodeFull(urldata), headers: {

  "Content-Type": "application/json"

}, body: { 

  "usuario": usuario, "pregunta": preguntaData, "mascota": mascota, 

 });

  if (respuestacitas.statusCode == 200) {

  final cargarDayaReserva = jsonDecode(respuestacitas.body) as List; 

  reservaMascota = cargarDayaReserva.map((e) => ReservaData.fromJson(e)).toList();      return reservaMascota; 

 } else { 

 setState(() { 

   mensaje = "cannot connect to the database"; 

 });

 } }

Don’t use “^” or any other special characters when specifying dependencies. Just a version you want.

These are my dependencies in flutter, I already made the change that I indicated but there were no changes in the execution of the system, it still generates the same problem.

dependencies:

  flutter:

    sdk: flutter  

  flutter_svg: ^0.19.0

  shimmer: ^1.0.1

  font_awesome_flutter: ^8.8.1

  http: ^0.12.2

  flutter_secure_storage: ^3.3.5

  cupertino_icons: ^0.1.3

[Suzuki Tomohiro]

Once you remove ^, remove Podfile.lock and run again.

ioRequest.headers.set(name, value);

I still don't get this error, I try running another application that I had and it works fine, but I run the one I have currently in development and nothing still comes up with this problem, I don't understand why.

[Alexander san]

I have tried searching various platforms for this error and I cannot find a solution to this problem.

[Suzuki Tomohiro]

Remove C:/src/flutter/.pub-cache and try again?

delete that file but it caused me more problems, because in that folder there are some dependencies or something important because when deleting it caused me more problems when executing. I get many more errors.

[Suzuki Tomohiro]

What errors?

[Alexander san]

this is my real problem

these are the problems that appear to me when deleting the .pub-cache folder.

They are more problems but I only took a screenshot of the ones I saw initially and finally

The characters in the images are not recognizable. Can you paste them into gist.github.com?

here paste the problems that I have are many but I only let myself copy those

[Suzuki Tomohiro]

I never seen these errors before. It complains Flutter’s material widgets. Did you upgrade Flutter SDK recently? Can you try reinstalling the stable SDK?

There is a way that I can send you my application so that you can see the code and see if you run the same problem, please help me, I don't know what happened, it is my thesis topic to be an engineer and I am making my apk for the first time in flutter but I do not know what happened, I was just finishing making a menu for a select with query to the database and the application closed and I was presented with that problem

[Alexander san]

You can send me your email to give you my file and you can see it

[Alexander san]

I don't know where I was wrong

[Suzuki Tomohiro]

Please ensure that all code you share to me is publicly available in GitHub. If you share any code to me, I might share it in this public mailing list.

By the way, you’re not answering my question: Did you upgrade Flutter SDK recently? Can you try reinstalling the stable SDK?

I don’t install apk. Can you reinstall Flutter SDK and ensure an empty project works fine?

> Hello friend, here is my apk in github, you can review it and see where I was wrong.

If I already reinstall the flutter sdk again it runs a new project and it works fine, but I start my project and it continues the same, I change all the files to a new project and then I install the dependencies and the same problem occurs I do not understand why.

[Alexander san]

Thank you very much for your help and for your time, I really don't understand why it is generated even if I start a new project but I'm rewriting the code to see what happens.
