filter property

ImageFilter filter

The filter to apply to the existing contents of the scene.

The scene must be explicitly recomposited after this property is changed (as described at Layer).

Implementation 

ui.ImageFilter get filter => _filter;
void filter= (ImageFilter value)

Implementation 

set filter(ui.ImageFilter value) {
  if (value != _filter) {
    _filter = value;
    markNeedsAddToScene();
  }
}
