I am using Android Studio as SDK Platforms and SDK Tools. Currently, I have a problem when running the android emulator using Visual Studio. I have checked flutter doctor and no issues has been found. However, it shows an error as below.
As i run flutter run --verbose to search for the problems, it shows more details of the error as below
Just for sharing. Since I installed android studio, visual studio and flutter in my device using windows 11 pro, it doesn't work. However, I solved this problem by downgrading the Windows version into Windows 10 Home and it solved this particular problem. Anyone who face the same issue might try this in your current device.
This look like gradle compatibility issue.
Step to solve.
create new flutter project. try to compile the prject, if it work fine.
compare the android folder with yours and replace what is missing with the new flutter project you created.
sync your project after.
file/invalidateCache
flutter clean
flutter pub get
flutter run
you should be fine
To solve your error you have to update your compileSDKversion to the newest version which is currently 31.
You can find the compileSDKversion inside android > app > build.gradle
android {
compileSdkVersion 31
...
}
Note: you have to close and open android studio again
I am trying to run flutter on android studio and I keep getting this error despite having created a virtual device. Please help.
How I solve this in VSCode
Go to in your terminal of the IDE (Android Studio or Visual Studio Code), and type flutter doctor and check if one of the dependences is missing.
In my case is the 'Android SDK reference is missing', fix it with: 'flutter config --android-sdk ' and run 'flutter doctor -v.'
I hope this work for you :)

I just updated Flutter plugin to 53.0.1, restarted Android Studio and hit "run" button and the error below show up:
Could not find an option named "devtools-server-address".
Close and reopen AndroidStudio resolved for me!
killall java
I downgraded from Flutter 2.0 to Flutter 1.22.5 and got this error.
To solve it,
Go to your terminal and write flutter channel stable.
Then run flutter doctor.
Now you may get another error like this -
If you have Flutter & Dart plugins already install, just ignore this error. This is a bug in Flutter 1.22.5 .
Just run the app and it will work fine!
I had the same issue but using VS Code on stable channel
Execute the following commands:
flutter channel stable
flutter upgrade
flutter clean
flutter pub get
Then, close and open your IDE
Follow the steps:
File -> Invalidate Cache and Restart. Run flutter clean Worked For me.
This so simple... Open terminal type flutter channel dev this solve your problem.
And after that flutter upgrade
Finally, flutter doctor
If it does not help:
Open terminal type flutter channel stable
And after that flutter upgrade
Finally, flutter doctor
Working without upgrading flutter
Safe fix for Mac (Android Studio 4.1+). It is in a different directory now, but the symbolic link helps.
Just run this command in the Terminal:
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
Change the version of the Android studio depending on what you have, I had 4.2 so used.
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.2/plugins ~/Library/Application\ Support/AndroidStudio4.2
Just Invalidate Cache and Restart. Worked for me.
Just close your all project and also close Android Studio and Reopen.
I have a Flutter project and I have run it, everything is fine for a moment. But after some run, an error occurred. I cannot run my flutter project again, this is the error message
Could not find an option named "dart-define".
Run 'flutter -h' (or 'flutter <command> -h') for available flutter commands and options.
How to fix this error? Thanks!
I have found the problems, I accidentally rename my Flutter SDK to "flutter ". So I just rename my Flutter SDK back to "flutter" and restart my Android Studio.
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
