Constructors

ImageWidget.asset({required String assetPath, BoxFit boxFit = BoxFit.cover, Widget placeholderBuilder(BuildContext)?, Widget errorBuilder(BuildContext)?, double? height, double? width, Duration fadeInDuration = _defaultFadeInDuration, Duration fadeOutDuration = _defaultFadeOutDuration, Curve fadeInCurve = Curves.easeIn, Curve fadeOutCurve = Curves.easeOut, Color? color, Alignment alignment = Alignment.center})
The ImageWidget.asset factory method creates an ImageWidget instance for displaying an image from an asset path, with optional customization options.

ImageWidget.bytes({required Uint8List bytes, BoxFit boxFit = BoxFit.cover, Widget placeholderBuilder(BuildContext)?, Widget errorBuilder(BuildContext)?, double? height, double? width, Duration fadeInDuration = _defaultFadeInDuration, Duration fadeOutDuration = _defaultFadeOutDuration, Curve fadeInCurve = Curves.easeIn, Curve fadeOutCurve = Curves.easeOut, Alignment alignment = Alignment.center})
The ImageWidget.bytes factory method creates an ImageWidget instance with the provided path, bytes, box fit, placeholder builder, error builder, height, and width.
factory
ImageWidget.network({required String imageUrl, BoxFit boxFit = BoxFit.cover, Map<String, String>? httpHeaders, Widget placeholderBuilder(BuildContext)?, Widget errorBuilder(BuildContext)?, double? height, double? width, Duration fadeInDuration = _defaultFadeInDuration, Duration fadeOutDuration = _defaultFadeOutDuration, Curve fadeInCurve = Curves.easeIn, Curve fadeOutCurve = Curves.easeOut, Color? color, Alignment alignment = Alignment.center})
The ImageWidget.network factory method creates an ImageWidget instance for displaying an image from a network URL, with optional customization options.
