Android Studio - Flutter plugin not installed; this adds Flutter specific functionality

Question

Considering that I had followed all this steps https://flutter.dev/docs/get-started/install/linux in my Ubuntu 18.04LTS, why this following problem continues to appear:

$ flutter doctor -v

Different from another similar questions here in StackOverflow, before I've installed flutter plugin the "[✓] Android Studio (version 3.4)" was equal to "[!] Android Studio", with same error messages. After I've installed flutter plugin (and dart), only "[!] Android Studio" still displaying the error.

Does someone know why? I've made many searches in my files, I have only one Android Studio installed. Why displays two? What "[!] Android Studio" refer to? Does command "$ flutter doctor" have a problem?

Answer 1

This post is for those who have gotten the plug-ins installed but still receive the warning.

Note: The Flutter team has created an issue for the inability of doctor to detect installed plug-ins. It's a know issue and they are looking to deprecate this detection feature of doctor:

My flutter and dart plug-ins are correctly installed but I still get the warning.

[!] Android Studio (version 4.0)
    ✗ Flutter plugin not installed; this adds Flutter specific functionality.
    ✗ Dart plugin not installed; this adds Dart specific functionality.

In my case ignoring the warning worked fine.

I tried re-installing plug-ins several times but that did not remove the warning from flutter doctor.

However, everything works fine. I can successfully create and run apps created from

• the command line with flutter create
• from Android Studio with File->New->New Flutter Project

I'm on Ubuntu 20.04 LTS and Android Studio 4.0.1 (installed through JetBrains toolbox)

I installed flutter via the snap store:

sudo snap install flutter --classic
sudo snap install flutter-gallery
flutter channel dev
flutter upgrade
flutter config --enable-linux-desktop

# wanted to try web, apparently requires beta channel
flutter channel beta
flutter channel upgrade
flutter config --enable-web

FYI, it took me a while to understand where the Flutter SDK was located. It is here: /home/(username)/snap/flutter/common/flutter

Plugins installed correctly, but still get warning:

Answer 2

This can be solved in simple steps:

Step 1: Open Android Studio

Step 2: Open Android Studio Preferences

Step 3: Go-to Plugins tab

Step 4: Click on MarketPlace tab

Step 5: Search for flutter in search box

You will see a list of plugins related to flutter. Click on the first one and check which version it is. Currently, the latest version is 37.1.1.

Step 6: Click on install. (It may ask you to install dart plugin also. Hit yes and android studio will install dart and flutter for you)

Ready to rock !
