In what file are flags, set in Google Chrome, being saved?

When running Chrome Beta Portable and changing a flag in chrome://flags, where (in which file) is the status of this flag being saved?

I tried running a program monitoring all the files in the Chrome Portable directory but it was next to impossible to determine which of the changes belonged to the newly set flag.

They are stored in the Browser block of the the plain-text file Local State, which is located in the User Data directory.

For example, the file

%localappdata%\Google\Chrome\User Data\Local State

Would contain something like:

{ … "browser": { "enabled_labs_experiments": [ "disable-gpu-vsync", "extension-apis", … ], … } …
}
