ResponsiveImage class

Responsive Image is a wrapper around Image, that allows for scaling of the image's width, height and scale. It does this by extending ResponsiveStatelessWidget, and assigning a scale for different device sizes.

Constructors

ResponsiveImage({dynamic key, required dynamic image, dynamic frameBuilder, dynamic loadingBuilder, dynamic errorBuilder, dynamic semanticLabel, dynamic excludeFromSemantics = false, dynamic width, dynamic height, dynamic color, dynamic opacity, dynamic colorBlendMode, dynamic fit, dynamic alignment = Alignment.center, dynamic repeat = ImageRepeat.noRepeat, dynamic centerSlice, dynamic matchTextDirection = false, dynamic gaplessPlayback = false, dynamic isAntiAlias = false, dynamic filterQuality = FilterQuality.low})
Constructs a responsive asset image, that accepts a path String to and image asset. @param scaleWatch The responsive scale for watch devices (default: 0.1) @param scaleSmallPhone The responsive scale for small phone devices (default: 1.0) @param scaleMediumPhone The responsive scale for medium phone devices (default: 1.0) @param scaleLargePhone The responsive scale for large phone devices (default: 1.5) @param scaleSmallTablet The responsive scale for small tablet devices (default: 1.8) @param scaleMediumTablet The responsive scale for medium tablet devices (default: 2.0) @param scaleLargeTablet The responsive scale for large tablet devices (default: 2.5) @param scaleMediumDesktop The responsive scale for medium desktop devices (default: 3.0) @param scaleLargeDesktop The responsive scale for large desktop devices (default: 3.6) @param scaleTelevision The responsive scale for TV devices (default: 4.2)
ResponsiveImage.asset(String name, {Key? key, AssetBundle? bundle, dynamic frameBuilder, dynamic errorBuilder, dynamic semanticLabel, dynamic excludeFromSemantics = false, double? scale, dynamic width, dynamic height, dynamic color, dynamic opacity, dynamic colorBlendMode, dynamic fit, dynamic alignment = Alignment.center, dynamic repeat = ImageRepeat.noRepeat, dynamic centerSlice, dynamic matchTextDirection = false, dynamic gaplessPlayback = false, dynamic isAntiAlias = false, String? package, dynamic filterQuality = FilterQuality.low, int? cacheWidth, int? cacheHeight})
Creates a widget that displays an ImageStream obtained from an asset bundle. The key for the image is given by the name argument.
ResponsiveImage.file(File file, {Key? key, double scale = 1.0, dynamic frameBuilder, dynamic errorBuilder, dynamic semanticLabel, dynamic excludeFromSemantics = false, dynamic width, dynamic height, dynamic color, dynamic opacity, dynamic colorBlendMode, dynamic fit, dynamic alignment = Alignment.center, dynamic repeat = ImageRepeat.noRepeat, dynamic centerSlice, dynamic matchTextDirection = false, dynamic gaplessPlayback = false, dynamic isAntiAlias = false, dynamic filterQuality = FilterQuality.low, int? cacheWidth, int? cacheHeight})
Creates a widget that displays an ImageStream obtained from a File.
ResponsiveImage.memory(Uint8List bytes, {Key? key, double scale = 1.0, dynamic frameBuilder, dynamic errorBuilder, dynamic semanticLabel, dynamic excludeFromSemantics = false, dynamic width, dynamic height, dynamic color, dynamic opacity, dynamic colorBlendMode, dynamic fit, dynamic alignment = Alignment.center, dynamic repeat = ImageRepeat.noRepeat, dynamic centerSlice, dynamic matchTextDirection = false, dynamic gaplessPlayback = false, dynamic isAntiAlias = false, dynamic filterQuality = FilterQuality.low, int? cacheWidth, int? cacheHeight})
Creates a widget that displays an ImageStream obtained from a Uint8List.
ResponsiveImage.network(String src, {Key? key, double scale = 1.0, dynamic frameBuilder, dynamic loadingBuilder, dynamic errorBuilder, dynamic semanticLabel, dynamic excludeFromSemantics = false, dynamic width, dynamic height, dynamic color, dynamic opacity, dynamic colorBlendMode, dynamic fit, dynamic alignment = Alignment.center, dynamic repeat = ImageRepeat.noRepeat, dynamic centerSlice, dynamic matchTextDirection = false, dynamic gaplessPlayback = false, dynamic filterQuality = FilterQuality.low, dynamic isAntiAlias = false, Map<String, String>? headers, int? cacheWidth, int? cacheHeight})
Creates a widget that displays an ImageStream obtained from the network.
