Answer 1

try flutter upgrade and then check flutter doctor

Answer 2

Try apt-get update and upgrade first. You may need to use sudo After that, run flutter doctor again.

Also, the error seems to suggest a network connectivity issue with 'clients2.google.com' so, please also check that your network connectivity is ok without blocking.

Answer 3

Most of the time flutter quits unexpectedly due to connection error.Make sure the connection is on or reliable.I Think there is a network error.

Answer 4

Look at the file that the crash report is written to. In your case it's at/home/dracula/flutter_10.log. You will find out exactly why it crashed.

Answer 5

This is surely network problem. since flutter works mostly on the network make sure everything is fine on your network.

Answer 6

It looks like you have something wrong with your network. Upgrade Flutter and try to use a VPN when you are using Flutter.
