I installed Flutter with following the documentation at their website but when I want to run it and perform pod install I get this error. I tried changing version of Cocoapods but it doesn't work. Does anyone have an idea?

Looking for related issues on cocoapods/cocoapods... Searching for inspections failed: undefined method `map' for nil:NilClass
The main reason for this error is because you're using the system Ruby (the Ruby version that came preinstalled on your Mac). The system Ruby is not meant to be used for development. It's for Apple's use only, and modifying it (by installing gems such as Cocoapods) might break things on your Mac.
Here are two sites that explain in detail why you shouldn't use the System Ruby on a Mac:
Why You Shouldn't Use the System Ruby to Install Gems on a Mac
Instead, I highly recommend installing a separate and newer version of Ruby using a version manager (such as chruby, rbenv, asdf, rvm). Here's a step by step guide for properly installing Ruby on a Mac.
And if you want to learn more about how Ruby works and why you're getting this specific error related to REXML, read this detailed article:
https://www.rubyonmac.dev/cocoapods-rexml-parse-exception
Finally, although you might see a lot of people telling you to use sudo to install gems, I highly discourage that. When you have a proper Ruby development environment, sudo is absolutely never needed. I've been working with Ruby for more than 12 years, and not once have I had to use sudo to install any gem.
Here's an article that explains Why You Should Never Use sudo to Install Ruby Gems.
