"Could not connect to lockdownd" while attempting to run flutter app - flutter

I am following the Get Started tutorial.
I can install everything, flutter doctor returns all checkmarks but in the end there is a message:
idevice_id returned an error:
ERROR: Could not connect to lockdownd, error code -2
Same message appears if I try to run the app using flutter run or if I try to list the devices using flutter devices.
The tutorial also states that:
Note: If the Run & Debug buttons are disabled, and no targets are listed, Flutter has not been able to discover any connected iOS or Android devices or simulators. You need to connect a device, or start a simulator, to proceed
I have two devices listed my Android phone and an iPhone simulator. Run and Debug buttons are ENABLED!
How can I run my app using flutter? It can be either using the command line or IntelliJ IDE.

Disconnect all iOS devices, then:
brew uninstall ideviceinstaller
brew uninstall libimobiledevice
brew install --HEAD libimobiledevice
brew link --overwrite libimobiledevice
brew install --HEAD ideviceinstaller
brew link --overwrite ideviceinstaller
sudo rm -rf /var/db/lockdown/*
Connect an iOS device, and choose "Trust" when prompted, after that:
sudo chmod -R 777 /var/db/lockdown/

This workaround worked for me when loosing the connection:
close everything (Visual Studio Code, Xcode, Simulator)
disconnect any physical device
Start Visual Studio Code
connect a physical IOS phone
Start XCode
build from XCode (it will work)
Disconnect your physical device
Start without debug
You will be prompted to connect to a device
and from there it worked again!
This just to help to debug the loos of connection bug. I have also observed that it begins just after the "stop debugging" command from Visual Studio Code.

I was having similar issues, and resolved them using the below. Hopefully this will help you. flutter doctor was telling me the answers, but they were a bit buried. Look for something like this:
[-] iOS toolchain - develop for iOS devices (Xcode 8.3.3)
• Xcode at /Applications/Xcode.app/Contents/Developer
• Xcode 8.3.3, Build version 8E3004b
✗ libimobiledevice and ideviceinstaller are not installed or require updating. To update, run:
brew uninstall --ignore-dependencies libimobiledevice
brew install --HEAD libimobiledevice
brew install ideviceinstaller
• ios-deploy 1.9.1
✗ ios-deploy out of date (1.9.2 is required). To upgrade:
brew upgrade ios-deploy
• CocoaPods version 1.2.0
There are four brew commands in there to run. When I did them, this problem disappeared for me. Good luck!

flutter Project is not working in simulator mac os

I installed the flutter and using android studio to run the flutter project on simulator. I clone the project from git and run it shows this error
Error: To set up CocoaPods for ARM macOS, run:
arch -x86_64 sudo gem install ffi
Error running pod install
Error launching application on iPhone 14 Pro Max.
but when I make the new basic project it runs fine but not the cloned project. I tried some stuff.
open ~/.profile and add these
exports export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
Also uninstall cocoapods and reinstall again. but nothing works for me.
what i am missing here?
Spending few hours on this problem finally it works for me.
Step 1: Uninstall the cocoapods by running this command in your project folder terminal
sudo gem uninstall cocoapods
Step 2: Install the cocoapods by running this command
brew install cocoapods
Note: Not forget to restart the android studio otherwise it would show another error. just close your project, close android studio, rerun the project or simulator.
Hope it will help someone.

Flutter: How to solve this Cocoapods version problem?

The App is working perfectly on Android but on iOS it shows me this Error when I try to launch:
Warning: CocoaPods minimum required version 1.9.0 or greater not installed. Skipping pod install.
CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart side.
Without CocoaPods, plugins will not work on iOS or macOS.
For more info, see https://flutter.dev/platform-plugins
To upgrade see https://guides.cocoapods.org/using/getting-started.html#installation for instructions.
CocoaPods not installed or not in valid state.
Error launching application on iPhone 13.
And I'm actually shocked by this Flutter command of Cocoapods version 1.9.0! because I have just installed the latest Cocoapods version which is 1.5.2 on GitHub through brew install cocoapods.
Did someone face this problem before?
Please help :'(!
Solved it by:
Uninstall Hebrew completely from Mac.
Install rvm.
Install latest ruby version through rvm.
Install cocoapods---> sudo gem install cocoapods.

flutter doctor - CocoaPods installed but not working

using zsh - use to work in bash
brew doctor - Your system is ready to brew.
flutter doctor gives this error
[!] Xcode - develop for iOS and macOS (Xcode 12.2)
✗ CocoaPods installed but not working.
You appear to have CocoaPods installed but it is not working.
This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
This can usually be fixed by re-installing CocoaPods. For more info, see https://github.com/flutter/flutter/issues/14293.
To re-install CocoaPods, run:
sudo gem install cocoapods
sudo gem install cocoapods
Gives this error
dyld: Library not loaded: /usr/local/opt/gmp4/lib/libgmp.3.5.2.dylib
Referenced from: /Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby

zsh: abort sudo gem install cocoapods
I can't get this error above corrected - any suggestions?
which pod
/Users/puser/.rvm/rubies/ruby-2.5.1/bin/pod
which gem

then

command gem "$#"
) || result=$?
hash -r
return ${result:-0}
}
which ruby
/Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby
Using the suggestion for this post, I was able to get cocoapods reinstalled with the commands below
gem native extension error while installing cocoapods
Open Terminal
curl -L https://get.rvm.io | bash -s stable
Reopen Terminal
rvm install ruby-2.6
rvm use ruby-2.6.5
rvm --default use 2.6.5
Then this installed cocoapods as expected
sudo gem install cocoapods
Use brew and gem
first uninstall by gem
sudo gem uninstall cocoapods
Install cocoapods by brew
brew install cocoapods
link using brew
brew link --overwrite cocoapods
First install brew package manager for Mac.
https://brew.sh
If you use macOS, system Ruby is not recommended. and you should not use it. its for system specific use. you need to install another one for user.
brew install rbenv
then install the latest version of ruby. as today its 3.1.0
rbenv install 3.1.0
then set the global version of Ruby to be used in all shells
rbenv global 3.1
close the terminal and reopen it again, to affect the changes.
and finally install cocoapods
gem install cocoapods
as you see you don't use sudo command. because you are not overriding system specific configurations. when you need to use sudo command means you are doing something that you should avoid it.
if you are using fastlane and still complaining about cocoapods, even cocoapods is installed properly, reinstall fastlane again:
brew uninstall fastlane
gem install fastlane
curl -L https://get.rvm.io | bash -s stable
rvm install ruby-2.6
rvm use ruby-2.6.5
rvm --default use 2.6.5
sudo gem update
sudo gem install ffi
brew install libffi
sudo gem install cocoapods
pod setup
this worked for me
sudo gem uninstall cocoapods
rvm install 2.6.5
sudo gem install cocoapods
I am using MacBook Pro (2020) with M1 and following steps worked
url -L https://get.rvm.io | bash -s stable
rvm install ruby-2.6
rvm reinstall ruby-2.6.6
rvm use ruby-2.6.6
rvm --default use 2.6.6
sudo gem install cocoapods
Finally you can run flutter doctor to confirm.
flutter doctor
Output will be like this...

This error took me about one week to solve :(
The problem is mentioned clearly in the flutter output like this
This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
I had a lot of versions of ruby installed on my mac So this error happened to solve this error follow these steps

Can't install Flutter on Mac

This is the only install that fails, I have already installed Flutter on 2 other Macs without any issue.
It's a MBP 15-inch, 2018 running Mojave.
What might interfere with the installation is SentinelOne, that's installed on this machine and that I can't remove, so I need to somehow work around it.
Here's flutter doctor:

Any help would be greatly appreciated.
I ran into the same issue few days ago.
First you have not completely installed all the requirements of Android studio and Xcode.These errors stamps from improper installation and configurations.
Follow these steps.
Install or reinstall Android Studio -for the latest version
Install or reinstall Flutter macOS
https://flutter.dev/docs/get-started/install/macos
Install or update Xcode - this takes nearly a couple of hours depending on your connections.
Once all is installed - you need to run the command Lines to accept the agreements for Xcode and Xcode toolbox.
Install cocoa pod also using the command Line as mentioned in the flutter guide.
Finally, make sure that your flutter path in located somewhere you can find it and create a .zshrc file and expose the path into this file. I recommend /Users/johndoe/Development
`nano ~/.zshrc'
export PATH="$PATH:[PATH_OF_FLUTTER_GIT_DIRECTORY]/bin"
per my recommendation it would look like this
export PATH="$PATH:/Users/johndoe/Development/flutter/bin"
you have to install brew for that, first of all you have to run this command and after that run all other command as suggested in flutter doctor result.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
download java from following link and install it.
https://support.apple.com/kb/dl1572?locale=en_US
Android studio 3.4 is not now supported with flutter, so as of now you can not solve this error.

UDID validation needed for iPhone XS ideviceinstaller using flutter - it is no longer 40 digits and has a dash in it

I am working with libimobiledevice where whenever I am in need to push a bundle to iOS device with ideviceInstaller I am facing problem with iPhoneXR devices.
This problem is because of UDID : idevicepair without a UDID specified does work, but the problem is I have multiple devices connected to my machine.
ErrorMessage :idevicepair -u 00008020-000625E#########
idevicepair: invalid UDID specified (length != 40)
Note: I am using flutter to install the requirements like Usbmuxd,libimobiledeivce and ideviceInstaller
This has been fixed in the latest version of libimobiledevice. If you're on Mac, try updating your version of libimobiledevice by running
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies ideviceinstaller
brew install --HEAD libimobiledevice
brew install --HEAD ideviceinstaller
