Stuck in Building Flutter App in my device

Since the system update of my Vivo y20i device, I am having trouble installing my flutter app. When I run (Ctrl+F5) my app it get stuck in Running Gradle task 'assembleDebug'... sometimes it is stuck in Installing build/app/outputs/apk/app.apk. My developer option is turned on and also the USB Debugging, I tried every solutions that I found here in stackoverflow and other websites:
I run the ./gradlew clean and ./gradlew build and also tried ./gradlew clean build
Uninstall the app in my device then flutter clean. I always do the flutter clean
I uninstall everything, Android Studio and VSCode, and I upgrade my Flutter SDK to 2.5.0, and also did this.
but I am still facing the same problem. When I try flutter run -v, it works but then I can't update my app or do any changes in the app. Please help.
Here is my flutter doctor -v

Sometimes the problem can be with ADB Server.
Run this:
adb kill-server
Connect your device again and it should work.
Also
Settings>>Accounts and sync>>Delete Work Profile or any User Profile created on your phone.

Flutter Doctor doesn't recognized the flutter and dart plugin even after they are installed

I have installed the Flutter and Dart plugins in android studio but flutter doctor doesn't recognize it at all. Plus, I am running my flutter project and the emulator from VS code and it works perfectly. It even works from the android studio as well but the error messages doesn't seems to go away.
Error in Command Prompt after running Flutter Doctor(Image)
But after creating new project from command prompt everything seems to be fine as shown in the picture above but running the flutter doctor results the same problem again!
I have already uninstalled the plugins restarted the android studio and again installed the plugins and restarted the android studio.
Already done this process a number of times.
All the path have been defined in the Environment Variable of the system variables.
Already tried running this command flutter config --android-sdk PATH_TO_ANDROID_SDK in my terminal.
These error occurred after updating Android Studio to 4.1 v from 3.5 v
I can't seem to find any solution as this error is haunting me.
Thank you in advance.

i had the same problem check: https://github.com/flutter/flutter-intellij/issues/4523
If you are on Mac:
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
For windows and/or Linux you can try Flutter Dev channel:
flutter channel beta
flutter upgrade

my advice for you is to uninstall the Android Studio completely, then downgrade the version. I had the same error, it started working after downgrading to Android Studio 4.0.2

Android Studio (not installed) in flutter in linux mint

I installed flutter and android studio following the steps in the flutter official page. I did it a month ago and then I used flutter doctor and I did not get any problems back then.
Now I tried again but I keep getting those errors
I have Android Studio installed (version 4.1)

If you are not installing android studio into the recommended location. Then you need to link it back for Flutter doctor to find it.
I install android studio to my home dir "/home/{$USER}/android-studio"
The quick and dirty way is cd into your "/opt" folder then symlink it
$ cd /opt
$ sudo ln -s /home/me/android-studio android-studio
Then run flutter doctor (or with a -v to see more detail) you should able to see it finds it.

First of all, run the command as said flutter doctor --android-licenses.
It will show you the licenses and you just have to type Y in the command line to accept them.
Secondly,it seems can't find Android Studio. If you have that, I suggest you to uninstall and re-install it clearly. Of course you should also install the Flutter plugin in Android Studio.
When everything is done just use flutter doctor. The last warning "Connected device" is going to be visible until you don't use an emulator or connect via USB debugging your phone.

With regards to Flutter not being able to find Android Studio: I had the same issue since upgrading to Android Studio 4.1 a couple of days ago. Since I use VS Code it didn't bother me too much. However yesterday I received an update notification from Flutter and after the update the problem went away.

Android sdkmanager tool was found, but failed to run

I'm trying to use flutter on Android Studio. I have the flutter plugin installed on Android Studio and when i try to create a new flutter project it behaves normally, in the sense of it lets me write the project name, the flutter sdk path and so on. But when i click on finish absolutely nothing happens. I just see the Android Studio Welcome page where i can create new Projects. So i figured I'd see what flutter doctor -v has to say about it and it gives me these errors:
So i try to find a solution by typing : flutter doctor --android-licenses but i get another error:
And yes i have set the PATH variable and i have installed Android SDK Tools.
I tried everything but nothing seems to do the job.
Any help would be appreciated.

if you are using windows OS, backup your data, reinstall windows..remember to choose option to keep your files and application..after finish..check updates and update windows..
then run flutter doctor --android-licenses
