My project was working okay before I got Flutter upgrade prompt. After accepting to upgrade flutter, I started getting the following exception and now with every flutter command I get this exception. Also since that problem started Android Studio does not pick up any running emulator. So basically, I'm stuck, please help. It just displays "Loading..." instead of displaying the running Emulator.
Version Information:
Android Studio 3.4.2 • Flutter plugin io.flutter 38.2.1 • Dart plugin 183.6270
I've change the permission for git.EXE to allow for read, execute etc but this has not helped.
ERROR MESSAGE:
CreateProcessW failed 5
Unhandled exception:
ProcessException: Access is denied.
I have faced the same issue after running the flutter upgrade command
Remove exiting flutter SDK from the directory "https://flutter.dev/docs/get-started/install" and download again and run the following command
flutter doctor -v
After running the flutter upgrade command in the Windows CMD I faced the same issue.
I then tried to upgrade Flutter SDK using the Android Studio terminal and it upgraded successfully.

I installed the flutter in my windows 11. When I open the new flutter project, after installing the flutter plugins, I got this error 'Pub get has not been run '.
I also clicked on get dependences and upgrade dependencies. But still getting the error.
Is there any solution.
This is a known bug in Android Studio. The message disappears, when I disconnect my phone from my MacBook and plug it in again. You could also try to restart Android Studio, use flutter pub get in your terminal or just press ignore.
Newbee here. Trying to run the android emulator for the generic first_app flutter application.

Other information:
Flutter Doctor is clean. That took hours.
Running from Android Studio works.
Launching emulator works correctly
Have tried Flutter Clean, Flutter upgrade, Flutter Master.
Have tried running from powershell with the same error.
Any assistance welcomed.
First you can check if the emulator is running or not by this command
flutter devices
Then you can directly run your app through
flutter run -d device-id
In my case, it was
flutter run -d emulator-5554
All, on a whim, I deleted my first_app and created it again via flutter create first_app.
Immediately running flutter run, it works!
I am getting this error code in my Visual Studio Code. How can I fix it?
I am using Flutter v2.5.3.
You can try fixing it by running this in the terminal:
Just copy and paste the below code into the terminal and run it.
dart pub global activate devtools -v 2.8.0
which downgrades the version to 2.8.0 (that works fine). I found the answer on GitHub.
I agree with RandomCoder's answer to avoid executing command
dart pub global activate devtools -v 2.8.0
every time before opening Visual Studio Code.
And also if you didn't know the location of the build folder mentioned by RandomCoder, I found the location after reading it here for the pub cache folder:
By default, this directory is located under . pub-cache in your home directory (on macOS and Linux), or in %LOCALAPPDATA%\Pub\Cache (on Windows). (The precise location of the cache may vary depending on the Windows version.)
After you found it, go to the \hosted\pub.dartlang.org\devtools-2.8.0 directory to copy the build version there and paste it in \hosted\pub.dartlang.org\devtools-2.9.2.
I still didn't know if there is any bad effects of copy pasting it to a newer version folder, but in my case it's working until now.
In my case there wasn’t any build folder in the devtools-2.9.2 folder.
I copied it from 2.8.0 and it now works.
For Android Studio
Close Android Studio
Rn dart pub global activate devtools -v 2.8.0 to downgrade (as suggested in a previous answer)
Open Android Studio
Run your build
For Visual Studio Code
Open Terminal
Run dart pub global activate devtools -v 2.8.0 to downgrade (as suggested a previous answer)
I fix this by:
flutter upgrade
This is an issue coming since yesterday. Maybe they must have updated the Dart engine.
There are two ways which will help you to solve the issue.
Update the Flutter SDK to the latest version and restart your PC:
flutter upgrade
Use the Dart Devtools manually
Run flutter pub global in another terminal. Run devtools and then open http://127.0.0.1:9100
Enter a running application field address of your running application in the Connect: "http://127.0.0.1:60230/J7_wS_YhTuo=/"
You can find this URL in debug console when you run the code.
√ Built build\app\outputs\flutter-apk\app-debug.apk.
Connecting to VM Service at ws://127.0.0.1:51849/mHlycLJYEWw=/ws
If you are getting any issue regarding the port, then do this in your Flutter project console
flutter run --observatory-port=9100
Once the application starts you can see the message in the console.
If you are getting any server issue in the web browser
then enter
dart devtools
In cmd
Downgrade to devtools-2.8.0
And activate using dart pub global activate devtools -v 2.8.0
These two steps worked in my case
First activate your devtool using this command...
flutter pub global activate devtools
flutter pub global run devtools
And after that, try launching it from Visual Studio Code as described in the documentation: Install and run DevTools from VS Code
When trying to run my app on chrome or macos after using dart migrate, I get this errors in the console:

It runs fine on the Android / iPhone emulators.
I tried the following but all in vain:
flutter 2.0.6 (stable)
flutter 2.5.3 (stable)
flutter doctor shows nothing wrong
flutter clean, flutter pub cache repair, flutter pub get
Restart VSCode
Actually, the issue was coming from the dependency styled_text.
I copied only the files that we needed from the repo and that solved the issue.
flutter app was working getting build and run on Xcode 10 on device iOS 12 fine before,
The time dart upgrade 2.1.0 happen in Flutter build iOS worked well with command and on Xcode 10 after build get success while running Flutter app on iPhone 7 iOS 12, it started giving error and app gets crash with following error message in Xcode logs.
Error is Runner[410:28754] [VERBOSE-3:dart_vm.cc(403)] Error while initializing the Dart VM: Wrong full snapshot version, expected '8343f188ada07642f47c56e518f1307c' found '46b2bfb57b5647c5f7527ff9aa56c69b'
Here are the details of the flutter sdk and dart .
Flutter 0.11.9 • channel beta • https://github.com/flutter/flutter.git
Framework • revision d48e6e4
Engine • revision 5c8147450d
Tools • Dart 2.1.0 (build 2.1.0-dev.9.4 f9ebf21297)
I have experienced this error and none of the above solution worked for me infact the option of clearing the flutter/bin/cache messed the entire vscode IDE.
So I deleted the entire flutter SDK and installed fresh new SDK from flutter official website.
After this installation everything was working fine.
I had this issue after a flutter upgrade. Uninstalling the app from the device and then flutter running it again solved the problem.
After deleting the flutter/bin/cache and running flutter clean, I couldn't get the dart sdk to load until I launched the flutter console (flutter_console.bat) that can be found in the directory where you installed flutter and ran flutter doctor there. That solved the problem.
Do git clean -xffd in flutter installed directory(repo).
If it's a Flutter project first try flutter clean if did not work, try above git command.
If still not solved, delete everything inside /flutter/bin/cache and try.
If still not :D,
Do flutter channel master, flutter upgrade, and flutter clean. If nothing worked please add a comment below.
If you are in Dart environment out flutter/bin/cach/dart-sdk, you may be not upgraded dart-sdk. This happen to me Dart 2.5.0 with chololate installed. So I just did choco upgrade dart-sdk
I have exactly this problem i Solve it how ?
by these comments you just update flutter
flutter channel beta
,
flutter upgrade
you should upgrade your dart sdk
So try this command :
choco install dart-sdk
if this is not work for you download it from this link
https://dart.dev/tools/sdk/archive;
and replace it with your current dart-sdk in flutter
I also have experienced the same issue. I upgraded the flutter version and later downgraded and encounter this issue maily on IOS adhoc build.
Solution:
Delete out $FLUTTER_HOME/bin/cache and run flutter doctor.
This will solve.
What worked for me was changing channel and upgrading and then changing channel back and upgrading.
I had to remove the flutter SDK folder in my computer completely and redownload the latest one at https://flutter.dev/docs/get-started/install/macos
Then, I ran flutter doctor.
You can find where your flutter folder is by typing which flutter in your terminal.
You don't need to uninstall the whole flutter and set environment path or anything else.
Just downgrade to any version by doing the below commands, suppose my current flutter version is v3.3.8 and I come across this issue then:
Go to flutter sdk-path in the command prompt and checkout to any branch you would like to switch for a moment, like v2.5.0. So,
By doing this you changed your repository from v3.3.8 to v2.5.0
git checkout v2.5.0
You can check previous flutter versions from here
link
Downgrade your flutter version to 2.5.0
flutter downgrade v2.5.0
Then upgrade flutter
flutter upgrade
