I have installed Flutter on Windows and checked all is ok using flutter doctor. I imported the Flutter plugin.
Now, when I try to create a new Flutter app via Anroid
I was struck with the same problem a while back. After a lot of stumbling I got it right.
First of all delete your previous cloned flutter files and install git in your user folder. Like
C:\users\username\
Clone flutter in your git directory,set the path
C:\users\username\git\flutter\bin
Now use the command flutter doctor If you have android studio and intellij IDE, install flutter plugins in both of them and now create a new project.
You are all set to go
