I'm trying to execute an http request to a local server that I did, but I'm getting the following I / flutter (28338) error message: Bad state: Insecure HTTP is not allowed by the platform: http: // mylocalip / auth / login, does anyone know how to solve?

Note: I am also using the modular flutter and mobx

I'm trying to make a request to a local http server, the request is a post for a login system that receives username and password by parameter

login() async {
try {
  var response = await http.post(http://mylocalip/auth/login,
      body: {'username': 'maximosdrr', 'password': '621251'});
  print(response.statusCode);
} catch (e) {
  print(e);
}
}

And the output on the console is as follows: I / flutter (28338): Bad state: Insecure HTTP is not allowed by platform: http://mylocalip/auth/login

To temp fix your problem. First add a config in res/xml(my full path is /Users/dolphin/source/third-party/Cruise/android/app/src/main/res/xml) folder:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

then in your AndroidManifest.xml file add this config:

android:networkSecurityConfig="@xml/network_security_config"

this could allow http traffic. But it just using to debug, the best way is to using https traffic. more info: How to allow all Network connection types HTTP and HTTPS in Android (9) Pie?
