Unhandled Exception: Connection failed in Flutter Xcode (AppClip)

Question

Code:

String url = "https://########.com/api/"
Response response = await http.get(Uri.parse(url),
headers: {
'Accept': "application/json",
},
);

Also added:

\<key\>com.apple.security.network.client\</key\>
\<true/\>

Error:

I tried Running it in xcode and getting this error while running AppClip on Xcode
