It might be one of your dependencies which is not yet compatible with Flutter web, try it with a fresh project.

  • I already tried to create the new project and paste all the classes even also update all dependencies but getting same error. – abhishek Jun 20 '20 at 14:11
  • I mean that if a fresh new project can build on web, it's probably one of your dependency in your pubspec.yaml which is posing problems so you should either swap it for a different one, or remove it on your web project. – BLKKKBVSIK Jun 20 '20 at 14:31

I had the same problem with a flutter web app, my mistake was that I moved one of my files to another location inside my project. The IDE (Android Studio) automatically changed the imports that referenced this file with something like this

import 'file:///C:Users.............';

As you may see the import had an absolute path respect to the file system of my OS (Windows 10)

My solution to fix this was change the import to a path relative to my flutter package

import 'package:my_project/src/...........';

I hope this may work on your case
