So, what I was trying to do is to build Windows desktop apps with Flutter. I just followed all the steps of installation that were written in the documentation of Flutter. I just created a simple boilerplate with the command flutter create learningflutter on my Windows 11 machine. Then I just run the flutter run -d windows command inside the directory (learningflutter), then ended up with this error:
$ flutter run -d windows
Launching lib\main.dart on Windows in debug mode...

I was looking for how to fix this problem. Would be appreciated if you teachers can help me out with this problem!

You can say that I have literally no idea about Flutter, and never made a mobile app with it. So, you can treat me a newbie and please explain why you did this or that or whatever so that I can learn.
If you need more information, please ask for it explicitly. I never dealt with these problems before so I don't really know specifically what to include as a reference! Thanks for your consideration!
Thank you Sir/Ma'am!
Make sure that you downloaded cmdline-tools
Run path/to/sdkmanager --install "cmdline-tools;latest"
and for the sdk license issue you may check this.

I'm a beginner at learning flutter. I've installed Android Studio and flutter. I ran the command flutter --version on Windows Powershell and the output I received is Flutter 2.2.3 • channel stable • https://github.com/flutter/flutter.git Framework • revision f4abaa0735 (2 months ago) • 2021-07-01 12:46:11 -0700 Engine • revision 241c87ad80 Tools • Dart 2.13.4
The next command I ran was flutter doctor and I received output as:

Can anyone please help me in fixing this issue?
I've the same issue on Windows. This does not seem to happen on Linux (Ubuntu) for me.
But it's a warning you can ignore. Even if Flutter Doctor does not recognize Android Studio, you can still use it in Android Studio if everything else is set up.
Working with Flutter I tried to use Xcode simulator and I get the error in the picture.
I searched everywhere and following all the possible solutions but nothing is right (gem install commands, pod install(*[!] No Podfile found in the project directory*.), brew commands...).
However, if I tried the last app that I made and I have no problems running the simulator. Why with this project? Thank you in adv!

Redit:
I figured it out. So it was missing 'a folder' or 'a file' in the IOS folder (either with or without Pods folder).
I do not know what was it to be more specific since I just change the directory (cd <your iOS folder>) and then recreate or update the folder (<flutter create .> .
You'll see that something will update then you can either try the pod install command or give it a shot and try the simulator (remember to go back to your project folder though) .
I just migrated a flutter app made on Windows10, to the Mac, and had problems with the app's execution. I searched the internet for similar errors and found several solutions, but none of them solved my case. I tried to delete the files podfile.lock, Podfile, .symlinks, Flutter.Frameword, Fullet.podspec, pubspec.lock, and after that, the code execution (with flutter run) returned this:
Error running pod install
I tried to run this line of code:
"pod install --repo-update"
And I received this:
[!] Unable to find a target named 'FirebaseApp' in project 'Runner.xcodeproj', did find 'Runner'.
I've tried several things and I don't know what's going on.

My app is connected to Firebase, android, and I'm studying flutterfire with iOS.
Open the terminal, navigate to the project, and type rm ios/Podfile
After that build the project with flutter build ios

Ive tried several solutions, like run invalidate & cache restart on android studio, reinstalling adb platform tools, reinstalling android SDKs or even downgrade/upgrade the android studio, all doesnt end with good result. For now, i run my project on android device via terminal
In my case it was due to different compile and target SDK versions inside app level gradle and library gradle. It was resolved by changing sdk versions from 26 to 29 in both.
Open another android project in new window (not a flutter project). Now you have two windows of android studio.
then device will detect on Android project. You will be able to connect your device for native android project. Then try again to detect device on flutter project.
Your device will show here.
This worked for me.
maybe

Gradle was downloading pgks with each launch try, some were unreachable, probably my current location issues,
anyway finally it came through - it took a lot of time though.
