Or like this

Step 0: then Use bypass command in VS Code

 Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

After that you can use normal commands for deploying apps.

Step 1: install g firebase tools.

npm install -g firebase-tools

Step 2: Enable web framework for flutter.

 firebase experiments:enable webframeworks

Step 3: Initialize firebase hosting.

firebase init hosting

Then do some project related setup.

? Detected an existing Flutter Web codebase in the current directory, should we use this? No
? Do you want to use a web framework? (experimental) Yes
? What folder would you like to use for your web applications root directory? hosting
Could not determine the web framework in use.
? Please choose the framework: Flutter Web

• *Keep in mind whatever files will be inside the root directory that files will be uploaded in my case it is (hosting) folder, so i moved my all dart/flutter app related files to inside this folder. and choose the framework to Flutter Web

Step 4: Deploy firebase.

 firebase deploy

Hurray!!!
