Constructors
- UIImage(String source, {Key? key, bool? isAsset, double? width, double? height, BoxFit fit = BoxFit.contain, Color? color, Alignment alignment = Alignment.center, BorderRadius? borderRadius, Widget? placeholder, Widget? fallback, String urlTransformer(String url)?, String? placeholderPath, Color? placeholderColor, bool showPlaceholder = false, bool allowExtensionlessUrl = false, UIImageNetworkBuilder? networkImageBuilder, UIImageSvgBuilder? svgBuilder})

Properties
- alignment → Alignment
-
final
- allowExtensionlessUrl → bool
-
When
true, network URLs without a recognized image file extension are still treated as raster images (e.g. API/CDN URLs likehttps://cdn.example.com/media/abc123). Defaults tofalse, which only accepts URLs matching a known image extension.final - borderRadius → BorderRadius?
