flutter failed to connect android device and off application on iPhone simulator

when I call debug mode on an android device

Error connecting to the service protocol: failed to connect to http://127.0.0.1:60027/bncnE_T-mWw=/

and also asks for permission to wifi, but through a notification, if I give permission, it shows a white screen and the same error

but everything starts quietly if you build the apk and install through it

with an iPhone simulator, the application starts and immediately closes, and in the android studio it is written that the connection is taking too long, it may have crashed
