Same issue here. When trying the sample project, it works. I think the problem has something to do with dependencies, but have not figured out in detail.

Same issue . It wasn't able to get the instance of browser.

I tried removing unused imports, in my case "import 'dart:ffi';" this was the unused import and ta daa ... it worked !!!.

i just don't know what exactly the problm was.

I have fixed that issue by installing the latest JDK and JRE and added both path to environment variables. it fixes my flutter speed but flutter run and apk building still taking the same.

Try with flutter run -d web-server, then open URL on Chrome manually.

Same issue: It use to take lot of time to load and 'r', the hot reload command never worked.

Answer 6

1. Remove all unused dependencies
2. flutter run -d web-server

The answer mentioned by @Giampaolo is a great workaround!
