macos flutter: Could not start Dart VM service HTTP server

[adnankaya]

Bug description

I was trying to run the flutter-examples on my macos and received following error

Could not start Dart VM service HTTP server: SocketException: Failed to create server socket (OS Error: Operation not permitted, errno = 1), address = 127.0.0.1, port = 0

I researched the error and found that the issue is related to network permission on macos.

Steps to reproduce

1. clone the syncfusion/flutter-examples
2. open with vscode, click Start Debugging, you will see error on debug console

Code sample

I opened a PR. Please review it.

open the file macos/Runner/DebugProfile.entitlements

<!--The below configuration is added to access the network for Maps samples-->
<key>com.apple.security.network.client</key>
<true/>
<!--The below configuration is added to access the network for Maps samples-->
<key>com.apple.security.network.client</key>
<true/>

SOLUTION: there should be a server and client both. the first permission can be changed from client to server.
<key>com.apple.security.network.server</key>
