I'm relatively new to Flutter but I already have developed and finished some Apps in Flutter.
Recently I noticed a weird behavior of commands with the keywords "dart" or "flutter" in it.
Here is an example:
I was trying to migrate an existing project to the new dart null-safety and typed the command dart migrate into my Visual-Studio-Code Terminal.
I was expecting an output like Migrating C:\.... as a response but instead got these three lines:
The command "git" is either misspelled or could not be found.
Building flutter tool...
Running pub upgrade...
and then the expected output:
Migrating C:\<project path>...
and so on.
So basically the commands work as they would normally do but I get these three lines before the output everytime. And it's not only with this command. Also basic commands like dart help or flutter doctor will get these three lines.
I don't know what I am doing wrong. I uninstalled Flutter and also removed it from the PATH and then reinstalled it freshly but it's still the same. I also searched the web but didn't found anyone who has the same problem.
Any help and explanation would be great. Thank you for your time :)
I think I know where the problem is. I ran the commands directly when I opened PowerShell. But the directory was something like C:\Windows\ and then it won't work.
After I did cd C:\Users\User all commands will work as expected.
I was just thinking that it doesn't matter from where I run dartand fluttercommands obviously you have to be in your user directory that they will work properly.

I'm new in flutter and trying to learn about it for the first time.
I'm following the instruction of flutter documentation in here
When in step to the setting environment, I follow the instruction here.
After restarting the pc, the next step I must running the command flutter doctor in cmd.
In this step, I get stuck because in cmd, flutter doesn't response anything.
I try to execute flutter inside VSCode It still stuck with loading.
I also try to running with android studio, Still the same, I get stuck with loading
What should I do?
I missed the important thing.
Just don't put it in the privilege directory.
I face this problem after every 2,3 days that VS code doesn't show devices even they don't show chrome or edge. Then I run flutter commands but flutter commands are also not working. no error, no output in CMD. Please tell me how to solve this problem.
This issue is caused by an extension.
This was how I solved my mine
just search for the extension uninstall or disable it.
Restart your vscode again.
Happy coding
I changed nothing, just worked on my Flutter Aplication, after the day i wanted to flutter run --release my app, but it didn't worked and i got this error message: Target file "lib\main.dart" not found. The day before everything worked fine. After a couple of times i tried it on another app, where i didn't changed something for a couple of days. But some of my other apps are working fine. The normal running in Android Studio is working normally on every app. Does anybody knwo what's the problem here?
My Error
My Directory
You are probably running your command on a different directory. Check your directory using pwd command on terminal.
Edit: As you use windows, make sure you open command line in your project directory.
See this tutorial.

I am running flutter on my windows machine, it was working earlier and I have created demo project with it.
Today when I run VSCode it asked me to update flutter and I did, but when it is updated it is not able to run any command. It doesn't do anything, neither error nor success. It just get stucked with any flutter command.
Note : It was working earlier, so there is no chance of setting environment variables, still I have double checked it and it is there.
I did not find any solution for this so the last available approach for me was to reinstall flutter SDK and it worked.
Note: If you are windows user, you might get an error about PowerShell version, you must have PowerShell version greater than 5.1
After latest Flutter 1.0 stable and Dart update to vscode, I,m unable to use hotreload from vscode. If I run it from a terminal everytnhing works fine. Flutter doctor has no complains and I'm not sure how to fix it. I tried to uninstall flutter and dart from vscode but no luck so far. The error I get is
../../third_party/dart/runtime/vm/object.h: 8954: error: Handle check
failed: saw Instance of 'HomePage' expected Closure
I searched to find a solution but so far no luck.
This appears to be a bug in Dart or Flutter. It's possible it's the same as this one:
https://github.com/flutter/flutter/issues/24710
Can you reproduce in a small sample that you could easily attach to that issue and add some notes on your environment (what platform, what device, etc.) and if you get a full stack trace dumped when this happens, include that too.
Thanks!
