UPDATE:
I tried with another clean new project. Hot reload works fine.
Every time I perform a hot reload on my VS Code, the hot reload gets stuck with the following message. Anyone knows the problem?
These are the things that I have done.
Terminal: Ran flutter doctor -- (everything ok, except a warning sign of a little bit outdated Xcode. I'm using Xcode 11.1.0)
Restarted VS
Restarted the entire machine
Running on both simulator and physical iPad
These are my specs:
Macbook Pro Early 2015
macOS Mojave
VS Code 1.52.1 (latest)
Flutter extension v3.18.1 (latest)
Dart v3.18.1 (latest)
Xcode 11.1.0 (not latest)
Debug console:
Launching lib/main.dart on iPad Pro (9.7-inch) in debug mode...
lib/main.dart:1
Xcode build done. 82.4s

if you are using Listview.builder or Grideview.builder then
comment it out or remove that code block.
sometimes it happens because of the unbounded height problem of
listview.builder and hot reload get stuck and fail to compile the
code.
I was try open DevTools in the browser and press Hot reload button and it's working!
Not sure which Flutter version you were using but you could be running into a case of https://github.com/flutter/flutter/issues/84347 which is related to isolates getting somehow stuck during hot reload.
I don't know the audioplayers library but I assume it uses an isolate in the background.
Delete the emulator and run flutter clean from the terminal.
Then create the emulator again and it will fix the issue.
Run flutter clean and run your project again and see if that solves the problem.

My flutter project runs on real devices with F5 or with
flutter run --release
on real devices connected to the PC. It also worked on emulators (Windows 10) and simulators (macOS) but it stopped, getting an endless loading screen right after splash screen. On iOS i got this message in the logs:
PET daemon has launched
Failed to initialize PET service. Exiting...
Failed to initialize the tracker
Anyone an idea?
Try these three one by one:
1- flutter clean , flutter doctor (then resolve if there are any errors)
2- Search for dart.flutterAdditionalArgs in your vs code settings.
and remove args against it.
3- go to Android Studio , Uninstall all the sdk tools you have installed ,then reinstall it
I found the issue. It was the internet connection. Tried another one and it works.
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
Hi i am using Visual Studio with flutter and i am having issues with the hot reload and hot restart.
1.For hot reload its not working at all, on the bottom right corner it shows "syncing files with android x86..." but after a second it disappears but nothing changes on the emulator.
2. For hot restart its taking alot of time on the first attempt but for the rest of the time it works fine.

What i tried to fix it:
Looked on stackOverflow and github for similar issues and tried their fixes which were:
- Deleting and downloading a newer version of VS code
- Downgrading to VS code 3.1.
- Switching to master channel
Nothing seemed to fix the issue so any help would be appreciated.
Run flutter doctor to fix the issue. If it can't detect the emulator, restart your VS Code and your emulator.
