Flutter/Dart Null Safety Migration

I am trying to migrate my Flutter/Dart project to use null safety. I have updated all of my dependencies and changed the sdk to use ">=2.12.0 <3.0.0". However, when I try to use the migration tool I get the following error:
When I look at my flutter and dart versions everything seems fine. I may be looking at it wrong, but below is the output from flutter doctor and brew info dart:

I'm suspecting that maybe I don't have the latest dart sdk like I believe I do. If that's the case then how do I upgrade without breaking anything?
UPDATE:
It appears I am using the latest version of dart. Going into the settings in Android Studio I can see it is pointing at the dart sdk that ships with flutter:
Have you run "flutter upgrade" in your terminal?

If this issue occurs both on Simulator and physical device, it's possible that timeouts in the Observatory port as mentioned on this thread. Try upgrading the Flutter version that you're using and see if it solves the issue. If it persists, run flutter run --profile --verbose to see more details on what's causing the issue.

flutter on mac desktop "No devices detected"

flutter upgrade

Did I miss anything? (I'm looking to develop a desktop app so not android emulator / ios emulator)
Whatever instructions you are following are out of date; ENABLE_FLUTTER_DESKTOP hasn't been the supported or documented way to enable experimental desktop support for several months (and the legacy code for it was recently removed). You need to enable it with flutter config as documented in the official instructions
Just Enable flutter desktop
flutter config --enable-macos-desktop

Flutter Issues with MacOS 10.15 Catalina

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