dart:html should not be suggested in a flutter context

[devxpy]

Thanks for all the great work on this plugin!

IntelliJ Idea 45.1.3
Dart plugin: 201.7223.43
Flutter plugin: 45.1.3

This is not a breaker, but I've encountered this too many times for it to be really annoying.

IntelliJ will recommend dart:html as the first fix for a missing import. Since dart:html is not supported by flutter, this just breaks the build and I have to manually fix the imports.
