I've resolved this issue (for now by configuring flutter to use Java 17).

It looks like Android Studio update installed Java 21 and by running: flutter create . I could see...

The configured version of Java detected may conflict with the Gradle version in your new Flutter app.

[RECOMMENDED] If so, to keep the default Gradle version 8.3, make
sure to download a compatible Java version
(Java 17 <= compatible Java version < Java 21).
You may configure this compatible Java version by running:
`flutter config --jdk-dir=<JDK_DIRECTORY>`
Note that this is a global configuration for Flutter.

Alternatively, to continue using your configured Java version, update the Gradle
version specified in the following file to a compatible Gradle version (compatible Gradle version range: 8.4 - 8.7):
/Users/hamishnorton/factory/flutter3244/android/gradle/wrapper/gradle-wrapper.properties

You may also update the Gradle version used by running
`./gradlew wrapper --gradle-version=<COMPATIBLE_GRADLE_VERSION>`.

See
https://docs.gradle.org/current/userguide/compatibility.html#java for details
on compatible Java/Gradle versions, and see
https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:upgrading_wrapper
for more details on using the Gradle Wrapper command to update the Gradle version
used.

I installed Java 17 from https://adoptium.net/temurin/releases/?os=mac&arch=any&version=17

Check it installed with: /usr/libexec/java_home -V

And set the flutter JDK directory with: flutter config --jdk-dir=/Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home

Upon running flutter doctor -v it shows Java 17. And on running flutter create --platform=android . the message has gone. And I can now launch the app.

What I am unsure about is that...

Android Studio Ladybug | 2024.2.1 Patch 1 Build #AI-242.23339.11.2421.12483815, built on October 11, 2024 Runtime version: 21.0.3+-79915917-b509.11 aarch64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.

Comes with Java 21 and this causes an issue for the mixpanel_flutter package. I've avoided the problem be pointing my flutter installation to Java 17 for now.
