Constructors
- ImageView(String imageUri, {Key? key, double? width, double? height, double? size, int? cacheWidth, int? cacheHeight, int? cacheSize, BoxFit? fit = BoxFit.cover, Color? color, EdgeInsets? padding, EdgeInsets? margin, String? darkImagePath, bool autoDarkMode = false, bool autoApplyKey = true, BoxDecoration? decoration, BoxDecoration? foregroundDecoration, Clip? clipBehavior = Clip.hardEdge, double? aspectRatio, BorderRadius? borderRadius, BoxShape? shape, BlendMode? colorBlendMode, Widget? errorWidget, Widget? placeholder, double? scale})
- 根据图片uri自动判断是使用本地加载还是远程加载
- ImageView.icon(String imageUri, {Key? key, double? width, double? height, double? size, int? cacheWidth, int? cacheHeight, int? cacheSize, BoxFit? fit = BoxFit.contain, Color? color, EdgeInsets? padding, EdgeInsets? margin, String? darkImagePath, bool autoDarkMode = false, bool autoApplyKey = true, BoxDecoration? decoration, BoxDecoration? foregroundDecoration, Clip? clipBehavior = Clip.hardEdge, double? aspectRatio, BorderRadius? borderRadius, BoxShape? shape, BlendMode? colorBlendMode, Widget? errorWidget, Widget? placeholder, double? scale})
- 跟默认构造器的区别是icon构造器默认是BoxFit.contain
- ImageView.local(String? imagePath, {Key? key, double? width, double? height, double? size, int? cacheWidth, int? cacheHeight, int? cacheSize, BoxFit? fit, Color? color, EdgeInsets? padding, EdgeInsets? margin, String? darkImagePath, bool autoDarkMode = false, bool autoApplyKey = true, BoxDecoration? decoration, BoxDecoration? foregroundDecoration, Clip? clipBehavior = Clip.hardEdge, double? aspectRatio, BorderRadius? borderRadius, BoxShape? shape, BlendMode? colorBlendMode, Widget? errorWidget, Widget? placeholder, double? scale})

const
- ImageView.remote(String? imageUrl, {Key? key, double? width, double? height, double? size, int? cacheWidth, int? cacheHeight, int? cacheSize, BoxFit? fit, Color? color, Widget? errorWidget, Widget? placeholder, EdgeInsets? padding, EdgeInsets? margin, String? darkImagePath, bool autoDarkMode = false, bool autoApplyKey = true, BoxDecoration? decoration, BoxDecoration? foregroundDecoration, Clip? clipBehavior = Clip.hardEdge, double? aspectRatio, BorderRadius? borderRadius, BoxShape? shape, BlendMode? colorBlendMode, double? scale})
