Just now I see some good news: https://www.reddit.com/r/FlutterDev/comments/13vo5a2/the_most_important_flutter_310_feature_that/ (ignore the title though...). It was a performance problem in the old days, so it was great that the problem disappears. However, it seems that the doc is not updated yet, so everyone reading MediaQuery page will still use the old way. Thus I create this super-tiny PR :)
