How to apply a patch in flutter directory ?

I want to apply a patch from this [PR](https://github.com/flutter/flutter/pull/137874) how to proceed ?
On my local machine i use the following in the flutter directory:

``` bash
curl https://patch-diff.githubusercontent.com/raw/flutter/flutter/pull/137874.patch > intrinsic.patch
git apply intrinsic.patch
```

How can I do the same from my CI ?
