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
Open in Android Studio - Preferences | Languages & Frameworks | Flutter

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
After upgrading to Flutter 1.17.1 and Xcode 11.5, I cannot build for iOS anymore.
Despite following all the direction in https://flutter.dev/docs/development/ios-project-migration
Anyone faces the same issue? Any solution?

Here is the output when I do
flutter run

Your Xcode project requires migration. See https://flutter.dev/docs/development/ios-project-migration for details.
Error launching application on iPhone 11 Pro Max.
Yes, in addition, I have to remove the above.
thanks
Came from 1.13=>1.17. It did not upgrade my project automatically so I had to work a bit in Xcode. I solved the issue by executing all steps listed on the migration page. Then executing:
rm -rf ios/Flutter/App.framework
rm -rf ios/Pod*
flutter clean
Build and run => success
My project ios build fails after Xcode updating to 11.4.
steps from the manual (https://flutter.dev/docs/development/ios-project-migration) have already been made by flutter automatically(?) - everything written there has been done.

After following the official guides, Like #iluvatar_GR suggests delete App.Framework in addition also delete Flutter.framework from the Frameworks directory.
Run flutter clean and try running.
If there are any other errors other than project requires migration you might want to run rm -rf ios/Pods and try again.
How can I open an existing Flutter project made by Android Studio on Mac-Os to export ipa version of app? Can it be done with Mac-Os version of Android Studio or I have to do it with X-Code? How?
Thanks in Advance
I could finally do that by accomplishing the following steps:
Copy the project into macOs (with X-Code Installed)
Open it by Android Studio (preferably latest version)
Enable Flutter and Dart plugin on Android Studio framework settings
Run command flutter packages get (Connection to Flutter repositories must be available)
Run flutter build ios --release as #Günter Zöchbauer truly commented
Connect iPhone device or simulator and run directly on your device
If some errors printed you may need to verify your developer account settings on X-Code or check Github page of your libraries for possible iOS issues
You can do it in XCode.
Ensure you run flutter build ios --release before you do.
Connection to physical iPhone device is not necessary. Run any sample project in xcode. Start a Simulator. (Only One simulator preferrably).
clone the repository from github into Mac (with X-Code Installed)
open terminal.
cd to your pubspec.yaml
flutter run (it will automatically run flutter pub get)
(It will launch on the already running iOS simulator)
follow steps on flutter.dev to install flutter. Above steps will only work from terminal if flutter doctor(any flutter command) is recognized
