[khanhnwin]

• Added LiveGenerative model functionality for bidirectional audio streaming
• Added Imagen model use for profile pictures
• Removed ScavengerHunt demo from Next since I incorporated Imagen into the Agentic App Manager
• Renamed the app name to remove Next 25 label

TODO on Tues May 20:

• Rename project folder to be Agentic App Manager (remove Next 25)
• Update Readme
• Update to latest Vertex AI in Firebase Release Firebase AI Logic

You'll need to update macos/Podfile as well. Or, just delete the macos Runner.

Good catch! I meant to delete it. Thank ya!

[domesticmouse]

I'd suggest having two main.dart instances, one for the default impl, and the other one (say audio_streaming_main.dart) for audio streaming.

[khanhnwin]

Didn't know that was an option! Done!

[domesticmouse]

I'd suggest changing the top level directory, while you are at it.

All your suggestions have been implemented @domesticmouse! Thank you!! Waiting for the new release to drop and I'll be ready to merge :)

@domesticmouse Looks like Colorist is breaking the tests because it's using pkg:firebase_vertexai instead of pkg:firebase_ai - I was going to update it for you, but figured we probably shouldn't do that until we're ready to update the codelab, agentic apps campaign docs, etc. It's not a breaking change so it's not urgent. Plus it's a pretty quick lift and shift swapping it out.
