I've tried adding a JAVA_HOME kind of solution but didn't work for me.
I had that problem today after updating Android Studio, and found an answer here:
https://github.com/flutter/flutter/issues/118502
The solution is basically:
Go to your AndroidStudio folder (normally C:\Program Files\Android\Android Studio in Windows)
Copy the content of jbr and paste the content into jre folder
Quick workaround from here: https://github.com/flutter/flutter/issues/118502#issuecomment-1384954269
Run in the terminal:
cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre
*solution for MacOS
I updated android studio to Electric El, but after updating, it is unable to find Java Runtime.
Flutter doctor gives this error and the code does not compile.

You can ignore the warning ✗ Unable to find bundled Java version. but the code will compile successfully.
Open the folder where Android Studio is installed.
In most cases, it is "C:\Program Files\Android\Android Studio"
Open the "jbr" folder inside the Android Studio folder ("C:\Program Files\Android\Android Studio\jbr"), and copy all contents in it.
Then go back and create a new folder called "jre" -> "C:\Program Files\Android\Android Studio\jre"
Paste all contents which you copied from "jbr" folder to "jre" folder.
Click Start and search for "Environment" and open "Edit the Environment variables" from search result.
Click to open "Environment variables"
On "User variables" pane click new and add new variable with name "JAVA_HOME" and path "C:\Program Files\Android\Android Studio\jre". Click OK to save.
Restart Android Studio and run flutter doctor. It will solve the problem.

I installed Android Studio 4.1 and tried to run the existing project. But it gives an error like this:
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
You have to set the JAVA_HOME Environment Variable.
On Windows, I solved the issue as follows:
Download the Java JDK from here and install it. (This links to version 15, which requires you to create an account in order to download. Version 16 is available to download without creating an account, but it has caused me an error that required me to downgrade.)
Set the "JAVA_HOME" Environment Variable:
Open Windows Search, type in “env”, and choose “Edit the system environment variables”.
Click on "Environment Variables...".
Click on "New".
Fill in the "variable name" field with "JAVA_HOME".
Fill in the "variable value" with the path to where Java is installed on your computer. (for me it was under "C:\Program Files\Java\<jdkversion>".)
Click "OK" and close all dialogs.
Restart your IDE / Terminal. (do not skip this step)
On Ubuntu 20.04 with Android 4.1, this error can be solved using the Snap version with:
flutter config --android-studio-dir=/snap/android-studio/current/android-studio
For Windows :
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
This command works fine if you have Android Studio installed. Flutter can understand the configurations of the Android Studio and you don't have to provide JAVA_HOME anymore.
Edit (Bonus) :
Also, download "Android SDK Command-line Tools" in android studio for android-licenses. Steps are shown in the image below.
You need to install Java JDK software which is required for the android studio.
sudo apt install openjdk-11-jdk
UPDATE: run flutter upgrade to upgrade to Flutter 1.22.2, which fixes compatibility issues with Android Studio 4.1. See related Flutter release.
This issue has been resolved v
See this issue regarding Android Studio 4.1 and Flutter
You can either downgrade back to Android Studio 4.0.2 or you can
install the latest JDK and update your JAVA_HOME variable and
PATH (OS dependent).
Note that if you choose to continue using 4.1 instead of downgrading,
flutter doctor will tell you Android Studio is not installed.
You need to run flutter config --android-studio-dir='<path to android studio>' in order to fix this issue. flutter doctor will now also
incorrectly report that the Flutter and Dart plugins are not
installed even if they are - you can ignore this.
Install Android Studio (skip this step if you already installed)
Goto
C:\Program Files\Android\Android Studio\jre and copy the path.
Make New variable called "JAVA_HOME". And paste above path as the variable value.
I set my JAVA HOME to the path,
/snap/android-studio/97/android-studio/jre/
Then I set my android studio config in flutter by using this command:
flutter config --android-studio-dir=/snap/android-studio/current/android-studio
My system is :
Ubuntu 20.04 with Flutter plugin version as 4.1,
In Mac:
In your terminal run
ECHO $JAVA_HOME
This will bring up the current path of java home.Pay close attention to the path that the terminal outputs.In my case i had System/Library instead of /Library/.../... typo as my path.So i simply corrected this in bash_profile.
If your path is correct but the error persists,
Right Click On Finder
Go To Folder
Bash_Profile
Add or Edit the Java Home Path
The path you add here should be the one your terminal output when you ran Echo $Java_Home..As long as this path that was echoed was/is correct..the below steps should fix the issue.
Then open your zshrc in a similar manner as you did with bash_profile and add the home path to the file.
You can also edit the bash_profile and zshrc files in your text editor.These files can be displayed using cmd + shift + . in your home folder.
After that,save,exit the terminal, close android studio and restart your machine.
Read this Article to learn more.
Locate where your Android Studio is installed.
For me C:\Program Files\Android\Android Studio
Check if the jre folder exists, Create a new folder called jre
Copy the contents of the jbr folder and paste them into the jre folder.
Check by running flutter doctor, and Restart IDE.
Thanks: roufy235 {cause}
For ubuntu 20.04 this solution will be appropriate: -
This link solved my problem. In short I would recommend to follow the simple steps, i.e.
Upgrade the flutter using flutter upgrade
Set the path of the flutter flutter config --android-studio-dir="/path/to/android/studio/"
Set the path in bashrc file by opening bashrc file(it is a hidden file)
export JAVA_HOME="/path/to/android/studio/jre/"
choco install javaruntime
If you use choco package manager. It will set the vars automatically.
This issue can also be caused if you have updated your Android Studio.
In that case.
For Windows
First Open the Users\username\AppData\Local\Google directory on your PC/Laptop and make sure to Delete the older version of your Android Studio.
e.g, Current version of Android studio is Electric Eel (2022.1).
Delete any other older version from that directory accordingly and restart your PC or Laptop.
Then try running your project.
Install openjdk-8 ....
You have to restart your terminal, the issue will persist even after download if you don't restart the terminal.
Follow react native guide to download openjdk for your environment. ...
https://reactnative.dev/docs/environment-setup
For Windows this worked
Go to C:\Program Files\Android\Android Studio.
Copy all the files inside of jbr directory.
Paste all the files into jre directory.
Then run flutter doctor. The issue will go away.

Download Liberica JDK and on installation it will automatically set JAVA_HOME environment variable.
Now you just go to Android Studio -> Project Structure -> SDK -> Point all jdk path to liberica jdk installation directory and apply.
You are done. Just restart android studio and gradle command will work.

So When I use flutter doctor --android-licenses I found this error also:
A newer version of the Android SDK is required. To update, run:
C:\Users\DELL\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update
When I tried to run this command C:\Users\DELL\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update I found this error:
Error: Could not find or load main class '-XX:+IgnoreUnrecognizedVMOptions
Caused by: java.lang.ClassNotFoundException: '-XX:+IgnoreUnrecognizedVMOptions
So any one knows hoe to solve this problem
Go to the directory C:\Users\DELL\AppData\Local\Android\Sdk\tools\bin\
and then write the command:
sdkmanager --update
After that, run:
flutter doctor --android-licenses
You don't need to reinstall flutter.
You should just go to android studio->sdk manager-> sdk tools-> clear tick from Hide Obsolete Packages and tick Android Sdk tools (Obsolete) in order to install.
Finally it will be installed and you will able use flutter.
P.s. Don't forget to run to flutter doctor)
The Screenshot
Navigate in cmd to the needed folder. I think it was:
cd C:\Users\DELL\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update
After this run the flutter doctor command.
