My computer restarted for no reason and now all settings in flutter running in vs code have changed. During restart, I got an option to verify the author or something. I believe to hit trust but after that, I can't compile my project anymore plus the default behavior of the mouse buttons has changed. Right-click now shows, change all occurrences instead of default options. My phone is connected but it doesn't show up in the emulator/phone section below.
The same project runs fine in android studio
1st run flutter doctor to check if there any problem with install.
try to clean the project using flutter clean and rebuil/ run again.
Also you can run from terminal,
you can just type on terminal flutter run and it show devices then select one.
For emulators type flutter emulators , it will show your emulators,
to run on emulators flutter emulators --launch deviceName.
here the short form.
flutter clean
flutter pub get
flutter run
It worked after reinstalling all my extensions, primarily dart and flutter a couple of times. Thank you #amsakanna

I recently installed Flutter on my Chromebook (4 GB RAM). I have been writing snippets of dart code using vscode with no issues. Recently, I decided to move into the flutter framework, and then when I try to run the default application generated after creating a new project, VS Code freezes after a while. I know initially this was supposed to take a while to load being my first time, but is over 1 hour the appropriate time?
I have tried restarting VS Code several times, but still the same output. I even switched to using Android Studio, and this even crashes after a while.
What could be wrong or what am I getting wrong? I followed the official installation process on both VS Code and Flutter.dev sites.
i will assume that you have set up your emulator correctly and you opened the emulator with these steps:
1- on your keyboard use ctrl + shift + p and choose Flutter: Select Device and wait for the emulator to open.
2- after the emulator starts, from the upper menu of VSCode select Run > Run without debugging.
the app should run, if the problem persists, in VSCode open a new terminal window and type :
1- flutter upgrade
2- flutter clean
3- flutter pub get
try to run the application hopefully it will run
So basically the problem is that I created a new flutter app, and the I opened the emulator(from android studio), and I clicked on run.
I had multiple problems that were related to heap memory and such, but I managed to solved most of then using all kind of methods from the internet.
I even deleted and installed Java and android studio multiple times, I changed the Enviromental Variables as the Internet suggested, but now, the current error that I get is this:
The Error Image
my flutter doctor -v:
flutter doctor -v image
I'm about to lose my mind, I'm on this issuse for a few weeks. please help me fix it
after your seggestion to add "gradle.properties" and adding "org.gradle.jvmargs=-Xmx1024m" to it (without the " "):
after
Perhaps you shoud add a line at end of file gradle.properties org.gradle.jvmargs=-Xmx1024m then clean the project, also validate cache and restart the android studio. It should works then.
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 trying to run flutter app in visual studio code by pressing F5,
connecting a real device, but unable to run the app
my android sdk path--
C:\src\flutter\flutter
my flutter app path--
D:\flutter\flut\flut
error message--
flutter doctor -v ----
Try the followings.
run the flutter doctor --android-licenses and accept licenses.
(it happened to me too)
Install the flutter & DART plugin in Android Studio.
Then run the project again
Add the flutter bin dir to your path
First you have to accept the licenses for Android SDK. Write the following commands in your terminal.
flutter doctor --android-licenses
After adding above command you have to accept all the list of licenses one by one to get ahead.
In your case, you have not installed dart and flutter plugin. So, close your project and go to "Welcome Screen" of IDE where you will see a "Configure" button. click on it and select "Plugins".
Now, search for Flutter and Dart and install both of them. After installing both restart your IDE to apply new changes.
Now, you're Done with the setup. Now, you can run your project in real device or emulator by configuring them.
you need to accept the android licence, to do so,
run the command
flutter doctor --android-licenses
in your terminal, and press yes when prompted in the terminal.
The flutter and dart plugins are also not installed on your Android Studio, to include these, add dart and flutter plugins and restart your Android Studio.
And finally run the command flutter doctor in your terminal and check every thing is installed correctly.
Had that issue. Had to downgrade Java from 11 to 8. After that I have been able to accept the all the licenses. But in order to run the app - had to upgrade back Java 11. And also has to be sure that that JAVA_HOME path is JDK, but not JRE. But that that is the next thing.
I have recently reinstalled Flutter, Android SDK and VSCode.
I start the AVD emulator successfully.
I run Flutter Doctor from the Command line successfully.
I run Flutter create successfully.
I run Flutter run successfully, the basic App runs on the MyEm emulator.
I then open VSCode and at Line 43 there is an error
Invalid override.
The type of 'MyHomePage.createState' ('() → _MyHomePageState') isn't a subtype of 'StatefulWidget.createState' ('() → State<StatefulWidget>')
Can anyone help explain why this is happening?
I would better recommend you take a look on this link to create your first flutter app
and this link
I was having trouble to create my first app and it helped me to create my first flutter app.
