Solving the "Unable to Find Bundled Java Version on Flutter" Issue

Flutter has quickly become a preferred framework for creating both Android and iOS applications due to its ease of use, powerful features, and vibrant community support. One challenge some developers encounter while working with Flutter is the "Unable to Find Bundled Java Version" error. Here we will guide you through understanding and resolving this issue.

Understanding the Error

When you create Flutter plugins or build Android applications, it often involves the Java Development Kit (JDK). The JDK is essential for compiling and running Java applications and is a critical component in an Android development environment. Flutter may fail to locate the JDK, resulting in the "Unable to Find Bundled Java Version" error.

Common Causes

Misconfigured Path: Flutter might not be able to locate your JDK because the environment variables are not set correctly.

Missing JDK Installation: The JDK might not be installed on your system.

Multiple JDK Versions: Having multiple installations of the JDK might confuse Flutter.

Flutter or Plugins Updates: Plugins or Flutter updates could occasionally cause issues with recognizing the JDK.

Steps to Resolve the Issue

Step 1: Verify JDK Installation

First, ensure that you have the JDK installed on your system. You can verify this by running the following command in your terminal if you're on macOS or Linux, or Command Prompt/Powershell if you're on Windows:

If the JDK is not installed or you're getting an error, you'll need to download and install the JDK from Oracle or OpenJDK.

Step 2: Set Environment Variables

Properly setting the JAVA_HOME environment variable can often resolve the issue. Here's how you can do it:

On Windows

Right-click on This PC or My Computer, and select Properties.

Click on Advanced system settings.

Click the Environment Variables button.

In the System variables section, click New and add a variable named JAVA_HOME with the path to your JDK installation, e.g., C:\Program Files\Java\jdk1.8.0_281.

Add ;%JAVA_HOME%\bin at the end of the Path variable.

On macOS/Linux

Edit the .bash_profile or .zshrc file in your home directory and add:
