ColorFiltered class Null safety

Applies a ColorFilter to its child.

This widget applies a function independently to each pixel of child's content, according to the ColorFilter specified. Use the ColorFilter.mode constructor to apply a Color using a BlendMode. Use the BackdropFilter widget instead, if the ColorFilter needs to be applied onto the content beneath child.

These two images have two ColorFilters applied with different BlendModes, one with red color and BlendMode.modulate another with a grey color and BlendMode.saturation.
To create a local project with this code sample, run:
flutter create --sample=widgets.ColorFiltered.1 mysample
