There seems to be something wrong with your configuration. Did you install Flutter and follow all the instructions from the website? Can you run `flutter doctor` and add the output to your question? — J. S., Feb 12 '20 at 10:26
well, i did...but again, i can't because as i said, i am new to this. let me run flutter doctor — Daniel Separe, Feb 12 '20 at 15:57
here flutter doctor's report https://www.screencast.com/t/pD8sAejEQ — Daniel Separe, Feb 12 '20 at 16:03
Have you accepted the Licenses like it's asking you? Next time please share the text, not a screenshot. — J. S., Feb 12 '20 at 16:16
But flutter doctor is saying that you still have licenses to accept. Try running `flutter doctor --android-licenses`. — J. S., Feb 12 '20 at 16:19
i really don't know how or where to run the command you suggested i run — Daniel Separe, Feb 12 '20 at 16:23
Sorry, that's not how StackOverflow works. We help you solve your problem through StackOverflow, not through external tools. — J. S., Feb 12 '20 at 16:23
Open the command line and run that command. If you are on Windows just press the Start key and write "cmd" and press Enter to open the command line. Then paste the command and press Enter. — J. S., Feb 12 '20 at 16:25
oh okay! so i did that and it says flutter is not recognized as an internal or external command...i must say, i installed flutter from android studio plugin marketplace — Daniel Separe, Feb 12 '20 at 16:28
You need to replace the `flutter` command with the full location of the flutter binary where you installed the SDK. As you seem to not have the flutter command available in your env. — J. S., Feb 12 '20 at 16:34
That comment was already the instruction. But this is already getting off topic from your original question. — J. S., Feb 12 '20 at 16:39

You can try running the assembleDebug Gradle task manually.

cd android
./gradlew assembleDebug --stacktrace

But there could be something wrong with your configuration. Run flutter doctor -v and see if everything is setup correctly.

Otherwise you can try deleting the Gradle cache folder which seem to bet at C:\Users\October Price.gradle\caches.

it appears flutter is not recognized in my windows since i installed it from an android studio. and i haven't accepted a license but i have no idea how to rectify that – Daniel Separe Feb 12 '20 at 16:59
i did delete the Gradle cache as you suggested but it didn't change anything – Daniel Separe Feb 12 '20 at 17:00
Then try to follow the Windows installation guide, especially the part with the 'Update your path' part: https://flutter.dev/docs/get-started/install/windows - I am not sure Android Studio actually installs flutter. – kuhnroyal Feb 12 '20 at 17:10
okay, so i deleted android studio from my computer and did a new installation with flutter as well and have it checked but i am still getting an error – Daniel Separe Feb 13 '20 at 05:48

Some `key.properties` file is missing, you should first try to run a simple example app. It seems you are trying to run an existing project without everything being setup correctly. – kuhnroyal Feb 13 '20 at 08:19
okay so following your advice, i run a simple app which run smoothly but when i copy the files from my old one to the new one, i get same error.... – Daniel Separe Feb 13 '20 at 21:44

now, there's a key.property file in the old one which i didn't copy. do i have to copy that too? – Daniel Separe Feb 13 '20 at 21:47
Probably, since it says that it is missing. This is nothing related to a normal flutter app though. – kuhnroyal Feb 13 '20 at 22:06

finally got it to run to run. thanks guys. your help was much appreciated. i must say login doesn't work and i am again stacked lol – Daniel Separe Feb 14 '20 at 00:15
It may be build for an older flutter version, but that's just guessing. – kuhnroyal Feb 14 '20 at 01:12

You can set your android compiler to always run with --stacktrace modifier.

Head to Settings > Build, Execution, Deployment > Compiler
Add --debug or --info or --stacktrace (Or combination of them) to the Command line options

In your case clearing C:\Users\October Price\.gradle\caches folder and re-syncing the project might help.

You can also use --verbose to get the full flutter stack trace. so for example:

flutter build apk --debug --verbose
