Describe the problem

Steps described in page to install cocoapods are incomplete. Also, the linked install guide is contradictory:

• here it states:

  We recommend you use the default ruby

  emphasis mine.
  Following this approach leads to flutter doctor complaining:

  CocoaPods installed but not working

• while here it states

  we recommend not using the system provided Ruby and instead installing a newer Ruby [...] with brew install ruby

  emphasis mine.
  While this approach works, the page doesn't mention the fundamental $PATH update step.

Expected fix

The page should enlist all the steps necessary to install cocoapods such as flutter doctor doesn't detect issues.
Steps I took to make it work:

• install newer ruby via Homebrew: brew install ruby
• update $PATH: export PATH="/opt/homebrew/opt/ruby/bin:$PATH"
• check that $PATH has been correctly updated:

  which gem
  # Should output /opt/homebrew/opt/ruby/bin/gem

• get gem installation directory:

  gem environment home
  # Should output /opt/homebrew/lib/ruby/gems/3.4.0

• include it in $PATH: export PATH=GEM_ENVIRONMENT_HOME_OUTPUT/bin:$PATH
• install cocoapods: gem install cocoapods

Additional context

Tested on MacBook Air M4

I would like to fix this problem.

• I will try and fix this problem on docs.flutter.dev.
