Code Action: Generate Interface

[FlagshipApps]

• Dart SDK Version (dart --version)
  2.12.0-133.2.beta on windows_x64

Problem
Oftentimes I write some kind of service and afterwards I want to create an abstract class from it, to implement dependency inversion. I always have to manually copy the whole class and delete the function bodies, which is annoying work.

Possible solution
A code action would be great. Like I can do "extract widget" in flutter, I'm thinking of a code action like "generate Abstract Class" or "generate Interface" when hovering over a dart class. The action should then create an abstract class (and maybe let me chose the name) which acts as an interface.

Example
existing class
class MyClass { void helloWorld(){ print("Hello"); } }
generated class after code action:
abstract class MyAbstractClass { void helloWorld(); }

FWIW every class is an interface in Dart so you don't need a separate abstract class to act as an interface for MyClass.

FWIW

Thanks for the hint! However, I think it does not change the benefit of the feature to generate a class without bodies to act as an interface, does it?
