Description

get-theme

Reproduction

Stackblitz doesn't include newest version of Angular Material (^18), so can't be produced.

Basically, an invocation of get-theme-color($theme, primary, neutral, 90) throws an error because it does not handle the case in which get-theme-color receives four arguments.

It can be seen in the picture below that, even though it is clear a function can expect 4 arguments ($theme and $args, where length of $args can be 3), the case for $args-count == 3 is not handled.

Expected Behavior

Handle the case for $args-count == 3, so get-theme-color does not throw errors when it receives 4 arguments.

Actual Behavior

Function get-theme-color returns a following error:

Function finished without @return.

Environment

• Angular: 18.2.6
• CDK/Material: 18.2.6
• Browser(s): all
• Operating System (e.g. Windows, macOS, Ubuntu): all
