public final class SpanStyleKt
public static final @NonNull SpanStyle lerp(@NonNull SpanStyle start, @NonNull SpanStyle stop, float fraction)
Interpolate between two span styles.
This will not work well if the styles don't set the same fields.
The fraction
argument represents position on the timeline, with 0.0 meaning that the interpolation has not started, returning start
(or something equivalent to start
), 1.0 meaning that the interpolation has finished, returning stop
(or something equivalent to stop
), and values in between meaning that the interpolation is at the relevant point on the timeline between start
and stop
. The interpolation can be extrapolated beyond 0.0 and 1.0, so negative values and values greater than 1.0 are valid.
