LocalContentAlpha

public val LocalContentAlpha: ProvidableCompositionLocal<Float>

CompositionLocal containing the preferred content alpha for a given position in the hierarchy. This alpha is used for text and iconography (Text and Icon) to emphasize / de-emphasize different parts of a component. See the Material guide on Text Legibility(https://material.io/design/color/text-legibility.html) for more information on alpha levels used by text and iconography.

See ContentAlpha for the default levels used by most Material components.

MaterialTheme sets this to ContentAlpha.high by default, as this is the default alpha for body text.
