Description

components/src/material/_index.scss

Lines 145 to 148 in 956b86f

	// MDC Helpers
	@forward './core/mdc-helpers/mdc-helpers' as private-* show private-using-mdc-theme,
	private-using-mdc-typography, private-disable-mdc-fallback-declarations,
	private-typography-config-level-from-mdc, private-if-touch-targets-unsupported,

The function typography-config-level-from-mdc is undefined in mdc-helpers. In fact, we can find the function here.

components/src/material/core/typography/_definition.scss

Lines 216 to 217 in 956b86f

	@function typography-config-level-from-mdc($mdc-level, $font-family: null) {
	$mdc-level-config: map.get(mdc-typography.$styles, $mdc-level);

The functions that are exposed with a private- prefix aren't public APIs.

@crisbeto Yes, I know private- is not public APIs. I just want to point it is a wrong expose. In fact, there is no typography-config-level-from-mdc in mdc-helpers.scss and it is defined in the typography/_definition.scss

[crisbeto]

Ah yeah, I think we can just remove those. IIRC we had to expose them for the legacy components which have been deleted.
