I am trying to develop a desktop application and I tried to switch to dev mode using this command flutter channel dev but since then all the flutter command I tried to run are not working. Below sis the error it's showing everytime I run any flutter command.
flutter/version: Operation not permitted
What can I do to solve this?
Easiest way would be to remove the current Flutter installation folder and extract a fresh one with the desired version. You do not have to change anything else, just extract the Flutter SDK in place of the old one and run flutter doctor.
in terminal write flutter channel stable
just run
flutter channel stable && flutter upgrade

Currently, i m using flutter 3.3.9 i want to update it to 3.7.3
Any particuler command?
Note : I don't want to affect my current code
Need perment solution for it.
Change channel if you are not in correct channel otherwise go to step 4
Open a terminal or command prompt on your computer.
Check the available Flutter channels by running the command flutter channel.
This will show you the list of available channels and the current channel you are on.
Switch to the desired channel by running the command flutter channel <channel-name>.
For example, to switch to the stable channel, you can run flutter channel stable.
Choose the version.
This is possible now with flutter version. In the console do flutter version to list the versions available. Then choose a version to switch to: flutter version v3.7.3
For these cases, try to use FVM (Flutter Version Management).
fvm install 3.7.3
fvm use 3.7.3
For get more detail here its official website https://fvm.app/
The advantages is you can any cases you can simply go back to your previous flutter version. And also you can work different flutter project with different version
I am trying to upgrade my flutter. When I hit flutter upgrade in the terminal in the android studio I receive the error 'Unable to upgrade Flutter: no origin repository configured. Run 'git remote add origin https://github.com/flutter/flutter''.
When I try to see flutter channels, I type flutter channel in the terminal in android studio, but I can't see any channels. The list is empty. Check the screenshot
After running the flutter channel stable in the terminal, it switched successfully. I ran the flutter upgrade command again and the same issue happened again. The screenshot is attached. New screenshot
Try flutter doctor, you will see flutter channel unknown. That is the reason, Flutter uses git to manage the Framework and when you checkout to different commit code / tags flutter channel changed to unknown.
Here is what you have to do:
flutter channel stable
Above I mentioned stable, if you need change the channel that you want to checkout (see available channels by flutter channel in terminal / cmd).
Then:
flutter upgrade
Everything should work now.
If not try below:
Go to flutter framework located directory and set upstream by git branch --set-upstream-to=origin/stable stable.
Please note that flutter channel stable is equivalent to git checkout stable if you try in flutter framework located directory.
Learn lot more info about this issue from already reported issue tracker.
Originally answered here.
try to run flutter stable channel and then flutter upgrade.
That should work.
Even when I run a new project in my device or emulator, during Assemble debug process a message appears in Debug Console 'Parameter Format not correct', but the app seems to run properly.
when I add 1-2 dependencies/ plugins, countless redlines occurs in Debug Console...
I don't know what is the reason and solution.
Sorry guys this happens every time you run a project build by the previous version of flutter... and this error is not a big deal... dont worry...
I have also faced the same issue. It started coming when I upgraded the flutter SDK to version 1.17.3. The easiest solution I can come up with is to downgrade the flutter SDK.
If you are using VS code then you easily switch between flutter SDKs from the bottom bar.
To add flutter SDK -
Goto file -> settings -> flutter SDK -> Add item
then you can give the path of other SDK.
If you are not using the VS code, change the path of SDK from environment variables.
If this doesn't work out, try changing the drive for SDK of flutter and android both.
Example- From D:\flutter to E:\flutter. I have not tried this but for my friend, it worked.
If none of these workes, just ignore this error. They might fix this in future upgrades.
it may be possible ,you have cloned the repo from github and trying to run on your local machine. just change the compileSdkVersion in android>app>build.gradle file, i was facing this issue and get it fixed now
android {
compileSdkVersion 30
}
I had the same issue, but it was fixed by running flutter doctor --android-licenses
I had the same issue try to change Your Environment variable path
If you're using VS Code, then you can try this process: Go to Settings -> Flutter SDK Paths -> click on Add Item. Then put the Flutter SDK location from your drive.
For example: C:\Flutter\flutter_windows_2.5.2-stable\flutter.
I hope it worked!!
Same problem, but it was fixed by running following command in terminal.
flutter doctor --android-licenses
When I run my application using the VS Code Run and Debug, The app is installed on my device and is stuck on a white screen. Meanwhile in the editor, the VS Code notification is stuck on "Installing build\app\outputs\apk\app.apk..."
I've tried to run different flutter apps on the physical device but was still met with the same error. I've also tried to run the flutter example increment app, but to no avail. I also uninstalled and reinstalled the flutter sdk from the stable GitHub branch but that also did not work. I've also tried solutions from about 22 other questions with similar problems.
However, when I use flutter run from the command line, the app installs and launches on my phone, however, I'm unable to use the Flutter DevTools Inspector.
P.S I've been able to debug flutter apps on the device with the Flutter DevTools in the past.
As of Flutter v1.20.2, this problem has been resolved. The linked GitHub issue is here if you disagree about the problem being solved.
You'll need to end the flutter, dart and flutter processes. So in terminal do this:
killall adb
killall dart
killall flutter
Then reload vscode
I am able to run the app in android studios but whenever I try in xcode I get a flutter framework not found.
upgrade your flutter by doing
flutter upgrade
and it will upgrade the engine and download necessary tools.
This will even kill flutter daemons.
And run the application again
flutter run
Make sure you open .xcworkspace (and not .xcodeproj in XCode).
Ensure you have 'Flutter.Framework' listed under "Linked Frameworks and Libraries". If not, just drag and drop it from the main project. Like below
I was facing the same error whene I try to archive in Xcode
I fixed it by
flutter upgrade
and
flutter run
I fixed this by switching to the master channel, and switching back to the stable channel. Also remember to run 'flutter upgrade' after switching.
Delete the flutter directory.
Download new flutter
Extract it and put it where you want.
Run the command export PATH="$PATH:`pwd`/flutter/bin"
if the command does not work then specify your path like bellow
export PATH="$PATH: /Users/{your user name}/Documents/src/flutter/bin"
Restart your machine and you are ready to go.
After that - inside your project's ios directory -
delete the .symlink directory
delete the Pods directory
delete the Podfile.lock file
and now run -
flutter clean
flutter packages upgrade
flutter build ios
For me nothing worked except, deleting my flutter files fully and reinstalling.
Use this flutter docs for reinstallation: Flutter Installation Link
I tried everything nothing worked except:-
Flutter upgrade
Flutter run
and boom- Build succeeded!
Please try the following steps:
Delete the flutter SDK
Download the same flutter SDK and re-install it
restart the android studio
It should be worked well.
Fixed by switching branches from beta to master
