Hello @Hixie
can you please review this PR?
Thanks

test-exempt: code refactor

Please don't forget to update the commit message above.

There's a bunch of places in this file that use "toDouble" that should now be redundant. We should remove those as well. (@a14n: might be worth a lint -- flagging cases where one has used toDouble() on a type we know statically to be a double, and similar, e.g. .round() on an int, or .toString() on a String)

If this lands successfully, we should also consider doing the next one up the chain, ExpansionPanel.

Thanks @Hixie
I have removed those and updated the commit message

Hey @Hixie
I have seen you in one of the boring flutter show
you are good tutor as well as Engineer
thanks for your hard work because I can see today is your holiday still you are doing work for make flutter better!

Why the .toDouble() for the expansion tile?

Also this probably fixes #11468

hello @MrBirb
because expansion tile has final int elevation;

we should file a bug about ExpansionPanelList using int for elevation now too

Sure @Hixie
And please assign to me!
Thanks

By "we" I meant "you", really. :-)

Great
