Autocomplete not working correctly in Android Studio with Flutter - First suggestions are irrelevant

Question

I installed Flutter and Android Studio. I ran flutter doctor - Flutter doctor

I have the Dart plugin installed - v191.8593.

When I press Ctrl + Space at a very obvious place the AutoComplete do not suggest the right suggestions. Example:

View animation here

As you see the first suggestion are not of type ScrollPhysics and are out of context, and after I scroll down, there are ScrollPhysics suggestions, but they are after some scrolling.

Cacophony

I believe I've ran into this when there were some parser errors in the file. Try fixing all parser errors including the completion location, wait a moment, and then editing the completion location again. – Upali

Have you tried this with VSCode and it gives the same suggestion list? – Chubb

@hola, What do you mean by parsing errors? – Cacophony

@sudo_kaizen In VSCode this is the same. – Cacophony

Remove Flutter And Dart Plugins and reinstall it will work for suggestion like stateless and stateful widgets if this don't work then remove all the plugins and reinstall will do!

I had the same problem and solved it by changing the first letter of my project directory's name from capital letter to lowercase letter. Example : "My_project" => "my_project"

Answer 8

First check in Android Studio > Settings > Editor > Live Templates that is it empty or not.

If it's empty then Make sure you have installed latest version of android studio and autosuggestion is on.

For checking if autosuggestion is on or not follow the steps given below; Android Studio > Settings > Editor > General > Code Completion

And finally follow below steps: Go to Android studio > File > Manage IDE Settings > Restore Default Settings

Restore

The One and only working solution , thanks – Dhow
