Hope you're coding well.

I am building flutter web app and need to be able to run it on local network with canvaskit build. A web request is sent to gstatic on initialization of web app from client side.

When not connected to internet the response fails to fetch canvaskit.js How can I make my app get this file from local server so the app can run without the need of internet. I have added the following lines to my index.html file and still requests for canvaskit.js:

and I have tried building web app with the following commands:

flutter build web --web-renderer canvaskit
flutter build web  --dart-define=FLUTTER_WEB_USE_SKIA=true --web-renderer canvaskit 
flutter build web --dart-define=FLUTTER_WEB_CANVASKIT_URL=./canvaskit.js --dart-define=FLUTTER_WEB_USE_SKIA=true --web-renderer canvaskit
flutter build web --base-href "/" --no-web-resources-cdn --dart-define=FLUTTER_WEB_USE_SKIA=true --web-renderer canvaskit

my flutter doctor is:
