[DioErrorType.other]: SocketException: Failed host lookup when running flutter app in macos

I am build the flutter app in macos(big sur) using this command:

~/apps/flutter/bin/flutter build macos --release

and I could found the app in the path: /build/macos/Build/Products/Release/reddwarf_dict.app/Contents/MacOS/reddwarf_dict, but when I run this app in macOS, shows error like this:

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: DioError [DioErrorType.other]: SocketException: Failed host lookup: 'api.example.top' (OS Error: nodename nor servname provided, or not known, errno = 8)

what should I do to fix this problem? what should I do to allow the network in macOS?

I add this config to the file macos/Runner/Release.entitlements and fix this problem:

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