I am building a flutter web app, but I want it to behave differently on mobile and desktop. To test it, is it possible to run the web app on a phone's browser or in the browser of an emulator? Thanks
No you cannot run a Flutter Web application in the mobile browser locally, if you want to test your application with a mobile format you can simulate it from a Google Chrome browser by enabling device toolbar from the developer tools Ctrl+Shift+M.
