override

calculateBackgroundImageFit(String? fillMode) → BoxFit

inherited

deactivate() → void

Called when this object is removed from the tree.

inherited

inherited

getBackgroundImage(String url, {ImageRepeat repeat = ImageRepeat.noRepeat, BoxFit fit = BoxFit.cover}) → Widget

Background Widget for container-style elements; supports network and data URLs.

inherited

getBackgroundImageFromMap(Map element) → Widget?

Builds a background image widget from an element map's backgroundImage.

inherited

getBackgroundImageProvider(String url) → ImageProvider<Object>

ImageProvider for DecorationImage backgrounds on container-style elements.

inherited

getDecorationFromMap(Map element, {Color? backgroundColor, BorderRadius? borderRadius}) → BoxDecoration
