The operation couldn’t be completed. Unable to locate a Java Runtime. Please visit http://www.java.com for information on installing Java

I couldn't run the flutter app on android emulator or android phone. I installed the recently released android studio for arm-mac platform on m1 mac. Please answer if I am doing anything wrong here or is it the problem with the release itself.

Debug console output:

The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.

Exception: Gradle task assembleDebug failed with exit code 1

flutter doctor -v output :

Why does my Mac say unable to locate a Java Runtime?

The message “Unable to load Java Runtime Environment” means that the Mac computer cannot load JRE, either because it is out of date or (more usually) because it has not yet been downloaded and installed. It can also happen after the computer OS X has been updated, e.g. to 10.14 Mojave from 10.13 Maverick.

Where is Java runtime on Mac?

Determining the JRE Version Installed on macOS From System Preferences, and then the Other section, click the Java icon. This starts the Java Control Panel. You then click About to display the version information.

Go to Applications then right click on Android Studio, then choose "Show Package Contents", create a new folder inside jre named jdk and copy the contents of jre to jdk

I downloaded Java 8 (but I don't think this guy did the work)
