I am configuring flutter SDK on my Linux Ubuntu 16.4 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 but I get this error when I run flutter doctor

Solution that worked for me:

1. Just install plugins.
   Studio>>Configure>Plugins>Browse Repositories
2. Search for flutter.
3. Tap on Install (a dialog will pop regarding dart dependency. click Yes).
4. Once the installation is finished restart android studio.

Now run flutter doctor.
