Flutter-intellij: Cannot override missing methods on newly created StatefulWidget

[gspencergoog]

Steps to Reproduce

If I type this:

class StatefulTest extends StatefulWidget {
}

Into a dart file, I get an analyzer error on the "StatefulTest":

This makes sense. But when I select "Generate...>Override Methods...", or hit "Ctrl-O", (with my cursor on the class name), I get this:

I'd really like to be able to easily create a new widget by just typing the class declaration, and then making skeletons of all the missing overrides.

Generate... > Override Methods... is implemented in Java in Dart plugin and is old code.
Ideally we should replace it with requesting members data from Analysis Server.
@jwren have you started working on this, or I can steal it? :-)

For you using Quick Assist (Cmd + Enter) might be a better choice.
It will do exactly what you need - add all missing overrides.

@scheglov - Go for it. Integration from DAS into the generator wasn't obvious to me into the Generator IJ framework. Alt+Enter on the error from the DAS, does the right thing so it hasn't been prioritized.

One difference between the Ctrl/Cmd-I and Alt/Cmd-Enter way is that I have to actually have the cursor on the class name to have the context menu appear, as opposed to anywhere inside of the class declaration.

This issue wasn't fixed yet.

A problem that is quite common to me when I extend a custom created class (like BaseViewModel for example) and want to override any specific method (Ctrl + O) the IDE says that no method where found to override.

This issue still exists in 2020.
When is it going to be fixed?
