recognize extends StatelessComponent, extends StatefulComponent

If I type class Foo extends StatelessComponent Atom appends {}. It would be even more helpful if it appended an empty build() method.

Similarly, if I type class Foo extends StatefulComponent Atom could generate a _FooState class and all the rest of the boilerplate.

Our plugin could make it easier to discover "quick fixes", which in this case can add missing methods like build(). Try Control-1, I think.

We can also argue that the analyzer should just add those methods anyway. If your class isn't abstract, and you just defined it, just fill in all the required methods. Filed dart-lang/sdk#25817 to track.

This is related to the question about aggressive constructor code completion (#1005) and would benefit from some experiments.

Is this still an issue?

Steve implemented live templates stless, stful and stanim to generate StatelessWidget or StatefulWidget boilerplate. It is even more convenient than partial code generation after extends StatefulWidget completion. Although you need to know that these live template exist.
