scale method Null safety
- double factor
Returns a new gradient with its properties scaled by the given factor.
A factor of 0.0 (or less) should result in a variant of the gradient that is invisible; any two factors epsilon apart should be unnoticeably different from each other at first glance. From this it follows that scaling a gradient with values from 1.0 to 0.0 over time should cause the gradient to smoothly disappear.
Typically this is the same as interpolating from null (with lerp).
