Flutter Issues with MacOS 10.15 Catalina - flutter

Question

After updating to MacOS 10.15 Catalina, there are problems with Flutter.
Specifically, Flutter doctor complaints about the following:
Downloaded executables cannot execute on host.
CocoaPods not installed.
It is important to explain that before updating, when my computer was running Mojave 10.14, these issues with Flutter did not exist, thus flutter doctor -v reported no issues whatsoever.
Regarding the first issue: Downloaded executables cannot execute on host.
Flutter doctor offers this link: https://github.com/flutter/flutter/issues/6207
Nevertheless, the linked article refers to Linux, not MacOS...
Regarding the second issue: CocoaPods not installed.
Flutter doctor suggests the following solution:
brew install cocoapods
pod setup
Nevertheless, although "install cocoapods" works fine, "pod setup" fails, indicating the following error:
/usr/local/bin/pod: /usr/local/Cellar/cocoapods/1.7.4/libexec/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/pod: line 2: /usr/local/Cellar/cocoapods/1.7.4/libexec/bin/pod: Undefined error: 0
Running flutter doctor -v offers the following result:

I humbly wish to ask for your help, please, to clarify what does it mean when it says Downloaded executables cannot execute on host?
and, what may be done to resolve it? Please?
also,
if cocoapods was running beautifully when using Mojave 10.14, what may be the issue now, being seemingly unable to successfully run pod setup?
is anyone else here having any issues with Flutter after upgrading to MacOs 10.15 Catalina Beta, which you were not having before with Mojave?
THANK YOU !!!
Update...
Researching about this issue, I've encountered a very sad comment, which suggests that basically there is no support for Flutter in Catalina...
Please find it here:
https://github.com/flutter/flutter/issues/34000
The comment says:
Flutter is not yet supported on macOS 10.15, although we're obviously looking at it. This is a duplicate of #22598, which relates to the removal of 32-bit support from Catalina.
So, I am beginning to think that it might be a good idea to go back to Mojave's safety, at least Flutter was working fine...
Please share your thoughts, suggestions, advise?

Answer 1

Its possible to install cocoapods, run flutter build ios and run on the iOS simulator.
brew uninstall cocoapods
sudo gem install -n /usr/local/bin cocoapods
pod install
Detailed instructions are here: This terminal won't let me run or install cocoa pods because I am on MacOS Catalina Beta?

Answer 2

For this issue:
[!] Flutter (Channel dev, v1.7.11, on Mac OS X 10.15 19A487m, locale
en-SE) ✗ Downloaded executables cannot execute on host. See
https://github.com/flutter/flutter/issues/6207 for more information
Easy fix:
Open a terminal on MAC and run the following commands:
> flutter channel master
> flutter doctor
Enjoy

Answer 3

Uninstall and install it again (fe if you are using homebrew).
Just run:
brew uninstall cocoapods && brew install cocoapods
