Answer 1

Make sure you have a JDK installed (you can get it here) and your $PATH and $JAVA_HOME are set up correctly. These sources can really help:

• http://www.sajeconsultants.com/how-to-set-java_home-on-mac-os-x/
• https://docs.oracle.com/javase/9/install/installation-jdk-and-jre-macos.htm#JSJIG-GUID-5F4A0659-BFC5-4CB9-9920-D2DEABF29894
• https://medium.com/notes-for-geeks/java-home-and-java-home-on-macos-f246cab643bd

In case you've already set them up, double check what's going on with your JAVA_HOME by pasting this in terminal:

echo $JAVA_HOME

It should output a path like this (the jdk version may vary):

/Library/Java/JavaVirtualMachines/jdk-16.0.2.jdk/Contents/Home

If it the path looks the same (or same with different java version), and you have also checked "where java", "java -version" etc, to make sure that the terminal recognises your java well and there is no other obvious java issue, that means that the only thing left is to run these commands one by one:

cd /Applications/Android\ Studio.app/Contents/jre

ln -s ../jre jdk

ln -s "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" jdk

Now if you run "flutter doctor -v", you should see no java errors and something like this instead of the previous error:

• Java binary at: /Applications/AndroidStudio.app/Contents/jre/jdk/Contents/Home/bin/java
• Java version OpenJDK Runtime Environment (build 11.0.10+0-b96-7281165)

Hope this helps! It solved the issue for me :)

I've been using SDK Man for years to install, update and change java versions with simple commands. It will take care of the installation and environment variable setup as well.

Here is a simple guide for mac users

Once the sdkman is installed, you can use it from the commandline:

sdk ls java

It will return a table with all the available versions. The cleanest choice is the lastest 'official' LTS version, where the vendor is Java.net and the current latest version is 11.0.11-open

Sdkman also helps you with a command sample at the bottom of the table, so for the current latest LTS openJDK, I would go with:

sdk install java 11.0.11-open

And that's all. Or if you have previously installed java versions (installed through other means) it is best to remove them.
