flutter run with flutter create app throws error - flutter

when I run the flutter create default app . my app is running but getting an error and it quits.
The error is :
Error connecting to the service protocol: HttpException: Connection closed before full header was received while flutter run http://127.0.0.1:64730/WQfPVkoQWyk=/
How to resolve this issue?

If you are using the emulator then changing the Android version from Q to Pie should solve the issue. This issue is addressed here

this happened after pub upgrade.
Though this issue seems to be common and can be caused by various situations, maybe you should check whether the SDK is selected.
In Android Studio, you can set the SDK in File -> Project Structure -> Project SDK, which works in my case.
Or else you can also try flutter clean && flutter upgrade.

Facing issue in a specfic flutter project while running over my ios device in flutter

Failed to establish a debug connection with 661e647d32d2bf1e57a60abeedda37a0af480e22 using mdns: Invalid argument(s): Cannot find executable for /Users/khattab/Desktop/flutter/bin/cache/artifacts/usbmuxd/iproxy.
There is no artifact, so probably build failed. You should check your debug console to see what is the exact problem.

flutter given error while running: Error waiting for a debug connection: Bad state: No element

I'm launching the app in a real device.
Anyone knows why this is happening?
Launching lib/main.dart on GT I9063T in debug mode...

Even the hello-world app is showing this error.
Run flutter clean.
This works for me.
I had this error with a clean install on MacOS X (Mojave), and after trial and error discovered that the main user who is running flutter debug needs to be an admin user.
Clue was the line:
log: Must be admin to run 'stream' command
when running from command line.
After this VS Code and command line work.
Build always works on my VS code normally. Updating to the latest Flutter 1.12 also started showing this and most times, my code either shows up on my device first before showing that debug has started or the program just quits. Any fix with VS code because I am not an Android Studio fan.
Try to change flutter channel to beta using "flutter channel beta". it worked for me to fix issue which is because flutter version is updated to "v1.12.13+hotfix.5".
I ended reinstalling flutter sdk.
Ubuntu 16.04
VSCODE
Started with Flutter 12. It seems that the user must be admin now.
Rolling back to a previous Flutter version will do for now.
flutter version v1.9.1+hotfix.6
I changed the channel of flutter to the master and works, I was using the stable channel.
You can use the command:
flutter channel master
or just flutter channel to see another channel.
In the 'Developer Options' of my phone, when I changed the 'Select Debug app' option to 'Nothing', the error was solved.
Try to downgrade the libglvnd package to version 1.2.0 in arch linux.
This started occuring after i updated xcode to 14.1.
