Why is HTTP Request on Flutter for MacOS desktop not working on Release?-CodePudding

I'm making a HTTP is debug or profile build, and it works fine. But if I switch to Release it no longer works

 [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: SocketException: Failed host lookup: '*******.*******.*****.io' (OS Error: nodename nor servname provided, or not known, errno = 8)
#0      _NativeSocket.startConnect (dart:io-patch/socket_patch.dart:681)

#6      _HttpClient._getConnection.connect (dart:_http/http_impl.dart:2808)
#7      _HttpClient._getConnection (dart:_http/http_impl.dart:2813)

I assume it's Internet permissions issue, but I can't find where I need to add permission (info.plist?) and what permissions I need to add?

Check this MacOS flutter documentation.

Add the below lines in the macos/Runner/DebugProfile.entitlements and macos/Runner/Release.entitlements:
