Set the JDK Location:
Here, you can see the JDK Location field. Click on the dropdown or browse to select the Java JDK version you wish to use, including Java 20. If you haven't installed it yet, you will need to download it from the official Oracle website or any other reliable source.
Step 3: Update Gradle Files
Once you have set the desired Java version in the JDK location, you will need to update your Gradle files accordingly.

Once synchronization is completed, it's a good idea to clean your project. Go to Build -> Clean Project and then Build -> Rebuild Project. This will ensure that all project dependencies align with the new Java version.
Conclusion
Changing the Java version used by Android Studio for your Flutter projects is a systematic process that can enhance compatibility and enable the usage of newer Java features.
