Flutter is a SDK, not a language. Maybe we'll add a new category for Android dev.

[jjangga0214]

@enkeyz I think it should be Dart(language-new category) > Flutter(new subcategory) order.
As Flutter is not only for Android but also iOS, web, and PC, IMHO, a new category for Android dev is not so good place for it to be.
Thanks ;)

You're right :) Added label.

How can I add flutter examples here?

[enkeyz]

Make a new category for Dart, then add a subcategory Flutter.
