Updated Macbook to Ventura - now getting 'command not found: Flutter'

Oddly enough I'm able to run my flutter applications, but I'd like to upgrade. However since I've updated to MacOS Ventura Flutter can't be found anymore...

output of echo $PATH:

/Users/me/bin:/usr/local/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/flutter/bin:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands

What the top of my .zshrc file looks like:

# If you come from bash you might have to change your $PATH.
export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH="$HOME/.oh-my-zsh"

Any help and info is greatly appreciated

>P.S dart and python also cannot be found. But they're not in my path so guess that makes sense

If you normally start flutter by typing:

Flutter

you can search in /usr and /opt for a file (rather than a directory) that is executable (i.e. a program) and called Flutter like this:

find /usr /opt -name "Flutter" -type f -perm +111

Then, if/when you find it, add the name of the directory that contains Flutter to your PATH. So if it finds:

/opt/homebrew/bin/Flutter

you would do:

export PATH=$PATH:/opt/homebrew/bin

If you don't find it in /usr or /opt, you will need to perform a more time-consuming search across the whole filesystem and also suppress error messages:

find / -name "Flutter" -type f -perm +111 2> /dev/null
