android studio - Flutter plugin not installed error; When running 'flutter doctor'

Question

I am configuring the Flutter SDK on my Linux Ubuntu?16.04 (Xenial Xerus) system. Why am I getting the following error when I run the flutter doctor?

I have specified both PATHS for flutter and dart in the .bashrc file, but I get this error when I run flutter doctor:

Safe fix for Mac (Android Studio 4.1+). It is in a different directory now, but the symbolic link helps.

Just run this command in the Terminal:

ln -s ~/Library/Application Support/Google/AndroidStudio4.1/plugins ~/Library/Application Support/AndroidStudio4.1

If you have a different Android Studio version or an installation folder, adjust the command accordingly.
