I'm developing a Flutter web application that needs to access APIs from different domains. Due to CORS issues, I need to run Chrome with the --disable-web-security flag. Currently, I can run the application through the terminal with the command: flutter run -d chrome --web-browser-flag "--disable-web-security" What I want is for VSCode to automatically use this flag when I use the Run & Debug button in VSCode, so I don't always have to use the terminal. Is there a way to configure VSCode to automatically run Chrome with this flag when debugging Flutter web? I'm using:

Latest Flutter version VSCode with Flutter extension Chrome as the browser for debugging

Thank you for your help.

I tried manually running my Flutter web application with the terminal command: flutter run -d chrome --web-browser-flag "--disable-web-security" This works correctly and allows my application to bypass CORS restrictions when accessing APIs from different domains. I expected to find a simple way to configure VSCode's Run & Debug functionality to automatically append these flags when launching my Flutter web app, but I couldn't find the correct configuration to do this in the VSCode settings or in the Flutter extension settings. I looked in the launch.json file, but I'm not sure about the correct format to add these Chrome flags. When I try to debug my application using the default Run & Debug button in VSCode, it launches Chrome without the --disable-web-security flag, causing my API calls to fail with CORS errors.

If you look in the project folder, you can find .vscode folder and launch.json file in that folder.

You can create it or let VSCode create it automatically if it doesn't exist.

In launch.json, add option below to the configurations .

      {
          "name": "chrome-debug",
          "request": "launch",
          "type": "dart",
          "args": [
              "--web-browser-flag",
              "--disable-web-security",
          ],
          "deviceId": "chrome",
          "flutterMode": "debug",
          "program": "lib/main.dart"
      }

Then you will have an option chrome-debug for VSCode start debugging.
