My App can authenticate successfully when debugging against the Android emulator, but if I try to authenticate using debugging against the physical device (with same OS version), an error message appears after more than one minute waiting:

Exception has occurred.

_TypeError (type 'String' is not a subtype of type 'int' of 'index')

The error message points to the following code:

        if (responseJson[AuthUtils.authTokenKey] != null) {

          AuthUtils.insertDetails(

              userNameController.text, passwordController.text, responseJson);

...

        } else {

...

        };

And in the DEBUG CONSOLE I get the following:

I/flutter ( 9531): Auth: SocketException: OS Error: Connection timed
out, errno = 110, address = example.com, port = 38975
V/InputMethodManager( 9531): Starting input:
tba=android.view.inputmethod.EditorInfo@4aece4e nm :
example.com.todoapp ic=null

Here is the screenshot:

What am I doing wrong here ?

I believe that in the line:

responseJson[AuthUtils.authTokenKey]

You're referencing an item in the list responseJson by the index AuthUtils.authTokenKey

And since AuthUtils.authTokenKey is a String, you cannot use it as in index of an array.

So you need first to get the index of AuthUtils.authTokenKey then use it to reference the item:

responseJson[responseJson.indexOf(AuthUtils.authTokenKey)]
