When building Flutter apps the ALT + Enter keyboard shortcut is very convenient not only to bring up Quick Fixes but also to bring up a popup menu to wrap/remove Widgets. It was working fine until I ran flutter upgrade and updated the Dart and Flutter plugins in IntelliJ (version 2018.3.5).
I have tried messing about with the keyboard shortcuts for an hour, disabling and re-enabling Dart/Flutter plugins, restarting and invalidating caches in IntelliJ, closing all other applications and rebooting Windows 10 numerous times. Nothing works. I can not get Alt+Enter to do anything anymore. It was working fine until I updated the plugins and the Flutter SDK, so it seems something in those updates broke it.
Actually, Alt+Enter doesn't seem to work for anything, and the "suggestion bulb" does not show up either. For example, if I type
String x = 2;
the 2 gets the normal red underline, but no bulb shows up and Al+Enter does nothing. I've trippel checked that the "show intention bulb" is checked in the settings and that the correct keyboard shortcuts are assigned (just to be sure I have reset them to Default).
Has anyone else experienced this lately and found a fix? I've tried all the suggestions I could find on StackOverflow, but none of them work and none of them specifically target the Dart/Flutter intention/action/quickfix popup.
EDIT
This is the IntelliJ log after restarting. I started with the Dart SDK that seems to break Alt+Enter, then switched to the other one which makes Alt+Enter work but disables the possibility to select a device to run the app on, then switched back to the first one again (see comments near the end of the log):

Here it is. You are welcome. 🤓🤓
Go to File > Settings > Editor > Intentions and Confirm the Dart Analysis Server.
For Mac OS:
Go to Android Studio -> Preferences -> Editor -> Intentions -> Quick assists powered by the Dart Analysis Server (Mark it) -> Apply.
After I did invalidate cache and restart, it worked fine.
I had the same issue. This solved it for me:
Switch to a different flutter channel. If you are on stable then go to beta or vice versa. Instructions on switching channels at this link:
https://flutter.dev/docs/development/tools/sdk/upgrading
Run flutter upgrade
Restart your IDE.
Check to see if the lightbulb (or ALT-Enter or Option-Return) is now active.
Switch back to your other channel and repeat steps 2 and 3 above.
When I imported another Flutter project I noticed that Alt+Enter was working fine in that project, but still not in the original project. I tried deleting all IntelliJ-related files (*.iml and .idea specifically) and recreating the original project - but Alt+Enter still didn't work.
That's when I started looking more carefully into the files in the lib source folder, and I found a suspicious file called analysis_options.yaml that I hadn't really noticed before. It contains
analyzer:
language:
enableSuperMixins: true
I deleted it (and the IntelliJ-related *.iml files and the .idea folder) and recreated the project - and finally Alt+Enter is working normally again!
The analysis_options.yaml file seems to have been added by a colleague a long time ago, so I'm still not sure why this problem didn't appear until after working on the project for a few months.
For those who are on Mac and nothing helps, try this:
Also, make sure that "Quick assist..." is checked (see #Gazihan Alankus's answer) and you have Dart and Flutter plugins installed on your Android Studio
For someone that might still have this issue.
If you have tried all the above and it still doesn't work.
Try disabling all your plugins and check if it has started working.
If it starts working
Enable your plugins one after the other to check for the plugin that made it not work
Check the shortcut of "Show Intention Actions" in the Keymap to see whether it's "Alt+Enter" or not. In my case, I'm using Mac OS X, Android Studio and the Eclipse Mac OS X keymap, and the shortcut of "Show Intention Actions" is "command+1".
