Packages roller blocked on JS interop errors #190355
Description
The flutter/flutter -> flutter/packages roller is currently blocked on JS interop errors. I've bisected it down to flutter/packages#12328 which is this Dart roll. I'm not familiar enough with the internals of JS interop to know what the solution is here to unblock the roller.
Target dart2js failed: ProcessException: Process exited abnormally with exit code 1:

Error: The '@JS' annotation on an extension type constructor has no effect.
external factory WebTweakMediaSettingsRange({num max, num min, num step});

Error: Compilation failed.
As usual with flutter/packages, if at all possible we want a solution that is compatible with both stable and master.

FYI @mboetger as this week's gardener, as this still isn't resolved.

I assume you meant @mdebbar not @mboetger :)

No, I wanted the current flutter/packages gardener to be aware of this blocking issue that had carried over from the previous week.
