How to identify which package is required and how can I solve this issue
I want to build my first flutter app in ubuntu 22.04LTS. And this problem is app isn't building:
CMake Error at /usr/share/cmake-3.22/Modules/FindPkgConfig.cmake:603 (message):
A required package was not found
Call Stack (most recent call first):
/usr/share/cmake-3.22/Modules/FindPkgConfig.cmake:825 (_pkg_check_modules_internal)
flutter/CMakeLists.txt:25 (pkg_check_modules)
i think you are missing this one. run this command and then flutter clean && flutter pub && flutter run
sudo apt install curl file git unzip xz-utils zip libglu1-mesa clang cmake \
ninja-build pkg-config libgtk-3-dev
if you still facing issue you have to folow these steps here to reinstall flutter on Ubuntu 20.04 |18.04 | 21.04 Linux

I install Homebrew.
Then I run command
"brew install cocoapods". It install successfully
but in flutter doctor i got error: cocoapods installed but not working properly. Error because of ruby incompatible version.
Tried another method
"sudo gem install cocoapods"
and got error:
While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0 directory.
This is m1 pro 2020 machine.
For MAC M1 chip Users try this solution
install ffi first (if not) In regular terminal using command: sudo arch -x86_64 gem install ffi then arch -x86_64 pod install --repo-update
Run flutter clean
Once complete, rebuild your Flutter application: flutter run
Try to avoid linking with system ruby and download a new ruby version using brew:
brew install ruby
Then add this line to .bash_profile or .zshrc
export PATH=/usr/local/opt/ruby/bin:$PATH
Close the terminal and open it again, then run this line to make sure the default ruby is the newly installed:
which ruby
Uninstall gem cocoapods and download it using brew
brew install cocoapods
I have a project with ionic 6 and capacitor, when I run ionic serve it work like a charm and I can see the project in my browser, but then when I run ionic capacitor build android I got this error:
error: unknown option '--npm-client'
[ERROR] An error occurred while running subprocess capacitor.
I have tried to use this solution, but it didn't work.
It says to:
npm uninstall -g ionic
npm uninstall -g #ionic/cli
npm install -g #ionic/cli
but I still get the same error. Someone already got the same error before?
Thanks!
npm uninstall -g ionic
npm install -g #ionic/cli#latest
Try this
I fix it updating to the last version with this, because the upgrade commands didn't work for me.
cd /tmp
wget https://registry.npmjs.org/#ionic/cli/-/cli-6.19.0.tgz
sudo npm -g install cli-6.19.0.tgz
I had the same issue and had to upgrade from node 14 to node 16.15 to make it work.
This issue is caused by older version of ionic-cli, you should upgrade the CLI version.
I'm having a bit of confusion about Dart and Pub installs on my system. I Use Android Studio and Flutter which comes with Dart, and if run Dart --version command in terminal I get Dart SDK version: 2.10.4 (stable) (Wed Nov 11 13:35:58 2020 +0100) on "macos_x64" which is the latest Flutter stable channel I installed.
Then to install Aqueduct with pub global activate aqueduct I was having the error pub command not found so I installed it and I had to also install PostgreSQL and Dart via home-brew .
Now to try and solve a bug that seems to be related to the latest version of dart Aqueduct db generate error: Bad state: NoSuchMethodError: The getter 'length' was called on null
I run brew install dart#2.8 but then if I run Dart --version again I still get Dart SDK version: 2.10.4 (stable) (Wed Nov 11 13:35:58 2020 +0100) on "macos_x64"

==> Caveats
Please note the path to the Dart SDK:
/usr/local/opt/dart#2.8/libexec
dart#2.8 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have dart#2.8 first in your PATH run:
echo 'export PATH="/usr/local/opt/dart#2.8/bin:$PATH"' >> ~/.zshrc

How can I check what versions I have installed on the system and Flutter?
Many thanks
Update
After running brew uninstall dart when I open the aqueduct project then I get Dart SDK is not configured message from Android Studio.
If I then point to the Flutter's dart-sdk folder Android Studio accept it but I need a 2.7 version to work well with Aqueduct's Postgres db.
So I guess the system should be set with both Flutter with its own Dart version for Flutter projects and a global Dart version for non Flutter projects like this Aqueduct project.
But then how do I set my path? Should I include both in my .zshrc file?
Not to answer your whole question... addressing this part:
I was having the error pub command not found so I installed it
pub is going away. Learn to start typing "dart pub" or "flutter pub", depending on which subset of commands you want.
Finally figured it out..
To have a different Dart version for non Flutter projects use Home-brew as install instructions say with brew install dart command and it will install the latest version.. If you need a specific version as I did install with brew install dart#2.7, and then to use it install docs says to use the brew switch dart command but I got the switch command is disabled in terminal message in terminal so I used the link command instead as suggested as brew link --overwrite dart#2.7
To set it in Android Studio the correct path is /usr/local/Cellar/dart#2.7/2.7.0/libexec as when installing it the dart#2.7 is keg-only, which means it was not symlinked into /usr/local, because this is an alternate version of another formula. message suggested it doesn't get installed in normal route /usr/local/Cellar/dart there you'll find the latest SDK installed with the first brew install dart command..
Update the path for it in .zshrc file and it's all done..
Hope this will help others as getting it set up correctly got me scratching my head a bit ..
Cheers.
I'm using VS Code to practice the Dart language (not flutter, I'm using Android Studio for that). My file's name is main.dart. Anyways, VS Code keeps telling me to upgrade Dart to the latest version.
Whenever I do, the command prompt/Powershell informs me that access to path 'dart.exe' is denied, specifically C:\tools\dart-sdk\bin\dart.exe.
How do I fix this?
You can upgrade dart SDK using flutter console:
1- Head to your flutter SDK folder path ( where you downloaded flutter SDK).
2- Open flutter console and type flutter upgrade --force.
This will upgrade both flutter and dart SDKs
you can upgrade dart sdk by using flowing command:
In Windows
choco upgrade dart-sdk
In Linux
If you’re using Debian/Ubuntu on AMD64 (64-bit Intel), you can choose one of the following options, both of which can update the SDK automatically when new versions are released.
Install using apt-get
Install a Debian package
Install using apt-get
Perform the following one-time setup:
sudo apt-get update
sudo apt-get install apt-transport-https
sudo sh -c 'wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'
sudo sh -c 'wget -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'
Then install the Dart SDK:
sudo apt-get update
sudo apt-get install dart
Install a Debian package
Alternatively, download Dart SDK as Debian package in the .deb package format.
Modify PATH for access to all Dart binaries
After installing the SDK, add its bin directory to your PATH. For example, use the following command to change PATH in your active terminal session:
export PATH="$PATH:/usr/lib/dart/bin"
To change the PATH for future terminal sessions, use a command like this:
echo 'export PATH="$PATH:/usr/lib/dart/bin"' >> ~/.profile

After a lot of searching I finally came across a solution that I believe works. If you are use Mac OS Catalina you need to use Brew.
Open Terminal on your Mac.
Now, run
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
Install cocoapods using brew
brew install cocoapods
cocoapods is ready to use now!
