Stuck at Syncing files to device Chrome... Flutter Web
Press F12 on Chrome and click on the Console tab to look for errors. Maybe you added something in index.html that is incorrect or there is build errors.
You can also run flutter build web to see if there's any errors.
I had the same error and solved it with flutter upgrade to the newest version.
For Flutter Web & Debug & Chrome:
- Version 1.20.0 stucks
- Version 1.22.0 works fine
A downgrade to Chrome version 84.0.4147.135 solved the issue for me.
