"Scope variables are not supported for web applications" warning

[elliette]

I'm on Flutter master, and connected to a web app. I'm using DevTools shipped with Flutter as opposed to running it locally.

• Whenever I type a ., I see the error "Scope variables are not supported for web applications", eg myRecord., mySet.. The first time this warning appears, what I'm typing disappears. After that the warning keeps getting appended to the line above what I'm typing.

Looks like this is coming from here:

devtools/packages/devtools_app/lib/src/shared/console/eval/eval_service.dart

Line 193 in dfa69f4

'Scope variables are not supported for web applications.',
