connection problem between flutter and mysql

I'm having a problem in flutter...

I'm trying to access my database and I get this error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Connection refused and changed IP addresses to my IP with 10.0.2.2:8000/api and with 127.0.0.1:8000/api.

Enter to give phpmyadmin to authorize the entry of IP.

with using Flutter laravel Php.

auth_services

class AuthServices {
  static Future<http.Response> register(
      String name, String email, String password) async {
    Map data = {
      "name": name,
      "email": email,
      "password": password,
    };
    var body = json.encode(data);
    var url = Uri.parse(baseURL + '/auth/register');
    http.Response response = await http.post(
      url,
      headers: headers,
      body: body,
    );
    print(response.body);
    return response;
  }

createAccountPressed() async {
    bool emailValid = RegExp(
        r"^[a-zA-Z0-9.a-zA-Z0-9.!#$%&'*+-/=?^_`{|}~]+@[a-zA-Z0-9]+\.[a-zA-Z]+")
        .hasMatch(_email);
    if (emailValid) {
      http.Response response =
      await AuthServices.register(_name, _email, _password);
      Map responseMap = jsonDecode(response.body);
      if (response.statusCode == 200) {
        Navigator.push(
            context,
            MaterialPageRoute(
              builder: (BuildContext context) => const HomeScreen(),
            ));
      } else {

      }
    } else {
      errorSnackBar(context, 'email not valid');
    }
