flutter-intellij: Flutter autocomplete suggestions not working

My autocomplete suggestions just stopped working. As an example, none of the widgets show inside suggestions window when I start typing, here is the screenshot when I want to add BoxDecoration:

Steps to Reproduce

I’m not exactly sure how this happened, but the issue started when I ran android emulator inside tool window ( I ran it as a separate window before.)

I created this project few days ago and everything was working fine until now.

Edit: I tried to fix it with invalidate caches and restart, flutter clean, without emulator running, running emulator outside tool window again. None of those things fixed the problem.

This just started happening to me after Flutter 3.0, suggestions like setState and overrides such as initState and didChangeDependecies aren’t working anymore. May we reopen this please?

Omg, finally I find out someone who has the same issue with a setState. I’m new to programming (and learning Flutter) and can’t realize the reason for such thing. So, this is just a glitch of 3.0 and will be fixed? 😉

I’m having problems related to imports too, the auto-complete only works when i force using CTRL + SPACEBAR two times

I’m using Flutter latest version (3.0.2)

Same problem… Android Studio Electric Eel | 2022.1.1 and Flutter 3.7.0

Suggestions not working but autocomplete works using CTRL + SPACEBAR two times

I second @thassio-vinicius this is a small issue but it lags the productivity of developer and it needs to be fixed

As a last resort I tried using git bisect to determine if it was a non-config related change and it was. For some reason quite a while ago I removed flutter as an explicit dependency in my pubspec.yaml 🤦 . Surprisingly everything continued to work except for auto-completions and running flutter tests via right-click.

Adding the following back has made everything work again, hopefully this solves it for someone else too:
dependencies:
  flutter:
    sdk: flutter

@rorystephenson Thanks for participating and presenting your solution.

Unfortunately, my pubspec.yaml file has those lines and autocomplete doesn’t work. Probably something different happened with my project 😦

It recently started to happen to me as well, and I think it was after updating to Flutter 3.0. I hope they fix it with a minor update soon.

@stevemessick I opened the project to test capitalization. Before I did anything I wanted to test if autocompletion works by some miracle so I went to my screen file and to my surprise, autocompletion now WORKS. I didn’t change anything nor did I open the project from the last time.

Before I opened this old project I worked on my current project and updated Kotlin and Dart plugins. I restarted AS and then opened my old project. Is it possible that this somehow fixed it ?

According to Google translate, the previous comment is:

I also encountered such a problem. I was learning Flutter development recently. When creating a project, the Model Name named a capitalized English word, and then auto-completion has been like this for the past few days that I have been studying, and it cannot be auto-completed. , today I accidentally changed the Model Name file name to English words starting with lowercase, and then opened the project in Android Studio, and auto-completion was fine.

That’s interesting. I’m not sure what Model Name refers to, but based on the capitalization comment I tried changing the name of main.dart to Main.dart and changed the project name in pubspec.yaml to use camel-case. Neither had an effect on completion, though.

@BojanDolic Could your project be affected by capitalization?
