Adding dynamic_theme and gemini_tasks (#2287)
Adds two new samples that use the Google Generative AI SDK for Dart. Both were created by @rodydavis. I'm merely the uploader so to speak. ## Pre-launch Checklist - [X] I read the [Flutter Style Guide] _recently_, and have followed its advice. - [X] I signed the [CLA]. - [X] I read the [Contributors Guide]. - [X] I updated/added relevant documentation (doc comments with `///`). - [X] All existing and new tests are passing.
