VS code Unable to connect to Chrome debug port: 37095 – Debian

I installed Flutter and VS Code in the following way:

$ sudo snap install --classic code
$ sudo snap install --classic flutter 
$ tail -n 1 ~/.bashrc
export CHROME_EXECUTABLE="/usr/bin/chromium"

$ flutter doctor -v

    The solution is that chromium, flutter and VS code have to be installed through SNAP.

    If you work behind a proxy, you should set env no_proxy=localhost,127.0.0.1.
    But if you are not using any proxy, try to install Dart Chrome Extension.

    Try running flutter clean and then flutter create .

    If that didn’t worked out delete your launch.json in your .vscode directory and then run your app, this issue occurs if there are any misconfiguration in launch.json file in vscode. and make sure your port is empty and not used by any other program such Microsoft IIS services or MySQL…

    to make vscode CTRL+F5 run in chrome or web-server go to your project root directory create .vscode directory and inside that folder add launch.json file.

    Now if you want to run in web server only from vscode debugger then add this lines in you launch.json

    {
 "version": "0.2.0",
 "configurations": [{
        "name": "Flutter",
        "request": "launch",
        "type": "dart",
        "args": ["-d", "web-server","--web-port", "8000"],
    }
]}

    And if you want to launch in chrome device change argument web-server to chome i.e.

    {   
 "version": "0.2.0",
 "configurations": [{
        "name": "Flutter",
        "request": "launch",
        "type": "dart",
        "args": ["-d", "chrome","--web-port", "8000"],
    }
]}

    Now run CTRL+F5

    If you don’t have problem in changing your port then try running your program from terminal with flutter run -d chrome --web-port XXXXX

    here XXXXX represents your port number.

    in my case;

    i was set the localhost to a local ip on hosts file of the OS for remote development and forget it. that’s why flutter run -d chrome gave the feedback connection refused.

    solution:

    in OSX, edit the hosts file located at /private/etc/hosts path and ensure localhost paired with 127.0.0.1

    that’s all.
