Flutter-intellij: Android Studio Editor IntelliJ Intention / Context Actions (Alt+Enter) not functioning

[SadSack963]

Suspected error in Flutter Plugin version 47.1.2 (My Windows 10 system).
Flutter Plugin version 46.0.2 works correctly (My Linux system).

If the cursor caret is placed at or inside a widget name, there is no yellow intention bulb, and Alt+Enter does not bring up the list of suggestions as stated here: https://www.jetbrains.com/help/idea/intention-actions.html

Right-clicking the widget name allows you to select Show Context Actions from the context menu, but then a message is shown "No context actions available at this location".

Right clicking on the widget in the Flutter Outline does bring up a context menu allowing to wrap with certain widgets (though there is no option to "Wrap with widget").

The red bulb does appear if there are errors on the line.

The yellow bulb does not appear when the cursor caret is within a widget name.
The yellow bulb does appear when the cursor caret is placed after the last ")," in a descending tree.
It also appears if the cursor is inside a text comment, and sometimes after the comma at the end of a parameter line, for example in the default project:

floatingActionButton: FloatingActionButton(
  onPressed: _incrementCounter,
  tooltip: 'Increment',
  child: Icon(Icons.add),

The yellow bulb appears when the cursor is at the end of the onPressed: and tooltip: lines only. The only context action is to Flip.

File menu -> Settings:

I think problem solved by me. You wants this like picture using shortcut with Alt+Enter shown the Show Context Actions.
Firstly you must install a plugin for Show Context Actions. You can follow that steps:
Open -> SDK manager -> left menu Plugins -> when on Marketplace search " Flutter Snippets" after that install plugin restart IDE.
Your problem solved.
Secondly your option; If you wants change shortcuts you can follow steps:
Android Studio File --> Settings --> Keymap --> Search this keyword "Show Context Actions" Right click Add Keyword Shortcut in area you can make the choice you want shortcuts. For example I want to chosee Ctrl+Space:

I hope help for you

Well, would you believe it! After a few hours sleep, I turn my Windows 10 laptop on, open my project, and suddenly it's all working properly again. I have done no alterations, no updates, nothing has changed, and yet... it works!

@SadSack963 thanks for the detailed report. You provided enough evidence that we know the analysis server was working. I wonder if there was a timing issue, which was resolved by restarting the IDE? At this point I think we do not know if the analysis server was working as it should. If you ever see a repeat of this problem could you check the size of the analysis server process? It if is simply huge then perhaps there is a memory leak.

I'm leaving this open for now because it sounds like there may be a problem.

@stevemessick Thanks for the comment. This issue has not yet reoccurred, so it was hopefully just a one-off event.

I just went through the same thing, but I noticed that my Flutter Inspector was freezed in my splashscreen class, so I refreshed it and the context actions returned. If it happens again, give it a try.

If you are using MacOS try closing Android Studio and making sure that it is not running in the background, then reopen it again, worked for me.
