background property

set background (BackgroundDrawable? background)

Setting this will notify all the listeners of this PainterController that they need to update (it calls notifyListeners). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.

Implementation

set background(BackgroundDrawable? background) =>
    value = value.copyWith(background: background);
