i'm trying to make a simple request to Flask but i keep getting connection refused.

This is my main.py

import os
import sys
from konlpy.tag import Kkma, Hannanum, Okt
from flask import Flask, jsonify
sys.stdin.reconfigure(encoding="utf-8")
sys.stdout.reconfigure(encoding="utf-8")


app = Flask(__name__)
basedir = os.path.abspath(os.path.dirname(__file__))


@app.route('/', methods=["GET"])
def index():
    return jsonify({'message': 'Hello, world!'})


if __name__ == '__main__':
    app.run(debug=True)

I started and got this message

* Serving Flask app 'main'
 * Debug mode: on
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
 * Running on http://127.0.0.1:5000

And on Flutter:

  final String baseUrl = 'http://127.0.0.1:5000';

  void _search() async {
    try {
      final response = await http.get(Uri.parse(baseUrl));
      final data = jsonDecode(response.body);
      print(data);
    } catch (e) {
      print(e);
    }
  }

I was reading this: why is flutter refusing to connect on localhost:8000 or 127.0.01:8000?

I'm using the android emulator, i also tried making the request to https://10.0.2.2:5000, but still didn't work. I also tried on my real device and got the same thing.

My computer is connected to the internet via cable, so maybe that's something to consider.

Thanks

From the flutter side you are using the wrong endpoint Change you baseurl from

  final String baseUrl = 'http://127.0.0.1:5000';

To

  final String baseUrl = 'http://127.0.0.1:5000/';
