Documentation for integrating with any flutter app

[raymon-io]

First of all thank you very much for open sourcing this project and maid. Would you provide documentation on how to integrate with any Flutter or dart application? Related to https://github.com/davidmigloz/langchain_dart/issues/317 End goal is to integrate with langchain_dart . If you could help integrate it into langchain or provide some guidance or documentation that would be great!
