Prefect Community

Hello, when creating prefect deployment with Python per the the docs it is:
```from prefect import flow

my_flow = flow.from_source(
    source="<https://github.com/PrefectHQ/prefect.git>",
    entrypoint="flows/hello_world.py:hello"
)

if __name__ == "__main__":
    my_flow()```
What if my flow script is not in main branch but in a feature branch, is there a way to specify branch name? I know with prefect.yaml file, there is a way to specify this.

Hi <@U05ASAZBJAZ> :wave: check out the example <https://docs.prefect.io/latest/guides/prefect-deploy/?h=#:~:text=private_git_storage.py|here>.

```from prefect.runner.storage import GitRepository
from prefect.blocks.system import Secret

    flow.from_source(
        source=GitRepository(
        url="<https://github.com/org/private-repo.git>",
        branch="dev",
    )```

we use to deploy using prefect.yaml file instead of configuring inside python code. which has flexibility of deploying different versions of code and different env for testing.
