🚀 [firebase_ai] Support for advanced Schema features with $ref and $def #17551
Description
There are some advanced JSON features like $ref and $def which allow for hierarchical structures etc.
They unlock a lot of powerful use cases, but they're not possible with Firebase AI logic right now. I think the two things we need are:
1. Support responseJsonSchema field in the API
Gemini can understand advanced schemas, but only when using the responseJsonSchema parameter rather than responseSchema (see GenerationConfig).
I believe Firebase AI Logic currently only supports responseSchema - see
2. Support $ref and $def in Schema
Currently, Firebase's schema object does not support representing $ref and $def, so I think we'd need some support here.
