Hi after installing flutter on our CI-Server I got the following message:
...
[Setup Flutter Android] [✓] Flutter (Channel beta, v0.0.0-unknown, on Linux, locale en_US)
...
had some already the same issue?
I also had this problem on CentOS.
It turns out that the default git installed in CentOs is too out-of-dated.
Please try upgrading git to the latest version on CentOS by following this answer link and then run flutter doctor again
I've encountered this problem on CentOS 7. This comment on github explains it.
It happens with git versions before v1.8.4 because of "git describe --first-parent" not being implemented in older versions. As for CentOS 7, newest git version that you can get using yum is unfortunately v1.8.3.1.
TL;DR use something like ius to get a newer git version.

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.
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"
Here is the print from console:

==> 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.
While running the latest chaquopy I am running into the error:
Collecting tensorflow==1.13.1
Could not find a version that satisfies the requirement tensorflow==1.13.1 (from versions: 1.10.1)
No matching distribution found for tensorflow==1.13.1
I am wondering if the internal chaquopy pip is too old and needs to be upgraded. How is this possible?
The issue isn't the version of pip, it's the version of TensorFlow. Try changing your project to use version 1.10.1 instead, as the message suggests.
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:
$ flutter doctor

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.
for More details you can refer this video.

As the title says, after updating MacOS to Mojave 10.14.4,
ios-sim showdevicetype returns zero results.
I am using Flutter as the mobile development platform.
I have also re-install ios-sim using
npm install ios-sim -g
but the results the same.
What happened?
In the end, I just issue the following command:
npm install ios-sim -g
And it works.. but I am not sure why it didn't work much earlier.
I have also faced similar issues and after spending multiple hours, this has been worked out for me.
flutter run -d com.apple.CoreSimulator.SimRuntime.iOS-12-2
If you are using the older build system then you can try with extra flag for Modern build system like this
flutter run -d com.apple.CoreSimulator.SimRuntime.iOS-12-2 --buildFlag="-UseModernBuildSystem=0"
Updating npm-install, iOS-sim is not going to make any difference.
Let me know if this don't work for you.
