运行 flutter 程序时出现问题

Question

While running visual studio code for a flutter program, I am getting this error log in the terminal tab.

Please help me to resolve it.

Thanks

flutter run -d chrome
Launching lib\main.dart on Chrome in debug mode...
Waiting for connection from debug service on Chrome...             26.1s
Failed to establish connection with the application instance in Chrome.
This can happen if the websocket connection used by the web tooling is unable to correctly establish a connection, for example due to a firewall.

Try running in release mode.

flutter run -d chrome --release
