SSH Connection not working in release build (apk installed on phone), but working on simulated phone in android studio.

Hello,
I am new to dart/flutter programming and wanted to programm an app to connect to my raspberry pi via ssh.

void main() async {
try {
client = SSHClient(
await SSHSocket.connect(SSH_IP, 22, timeout: Duration(seconds: 10)),
username: SSH_user,
onPasswordRequest: () => SSH_password,
);
print('connection success');
state = 'connected';
runApp(MyApp());
} catch (e) {
print('connection error');
state = 'not connected';
runApp(MyApp());
}

this is my code to connect to the pi. It works on the simulated Pixel 8 Pro. But when I install it on my real phone it doesnt work. It does work when I use a dedicated app (Terminus) on the PlayStore.
Does build.gradle have something to do with this?

Hi, you might want to add network access to the app

The first comment of this stack overflow should solve it
