iOS simulator for flutter

Question

this is my second day on Mac. I just bought the new M1 one and I started installing my apps. I was building some apps with Flutter in Windows. Now I installed Xcode and it's working with iPhone 13 emulator but it's not showing is vsCODE.

This is the output of Flutter Doctor

On Mac you still have to start your Emulator in XCode, then after you created your Flutter Project you can open the directory on VS, do not forget to install the Flutter Plugin in VS.

I had a rough time a new macos user. I tried

sudo gem install cocoapods

then got the response

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

    current directory: /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.0/ext/ffi_c

checking for ffi.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

i had installed cocoapods earlier using homebrew.

So instead this worked, you have to get the latest version first with homebrew.

brew install cocoapods

then

brew link --overwrite cocoapods

flutter doctor -v

will output
