    "Unsupported class file major version 61" indicates java 17, which is used by Gradle.

    https://stackabuse.com/bytes/fix-java-error-unsupported-class-file-major-version-63/

    This indicates major class version and corresponding Java versions.

    https://docs.gradle.org/7.3/release-notes.html

    Per this link, Java 17 support was added circa Gradle 7.3, so either upgrade to a more recent version of Gradle, or change your settings to use an earlier version of Java (such as JAVA_HOME if using the CLI).

    If you run flutter doctor, you probably will see:

    [!] Android Studio (version 2022.1)
    ✗ Unable to find bundled Java version.

    https://github.com/flutter/flutter/issues/118502 seems to be the latest issue in which this crops up. https://github.com/flutter/flutter/issues/106674 notes they reverted a buggy change, but it hasn’t hit stable yet, so you’ll have to symlink the bundled JRE folder as a workaround til the next AS update.

    e.g. for mac, you can use:

    cd /Applications/AndroidStudio.app/Contents
ln -s jbr jre

    For Mac:

    Go to finder and find Android studio:

    right click and click show package contents
    Create a new folder called jre
    copy the contents of the jbr folder and paste them into jre folder
    reload your terminal and type flutter doctor

    For Windows:

    C:Program FilesAndroidAndroid Studio
    then copy the content of jbr and paste the content into jre folder
    run doctor again and problem solved
