ImageExt constructor

  2. required ImageProvider<Object> image,
  3. CustomImageBuilder? imageBuilder,
  4. ImageFrameBuilder? frameBuilder,
  5. ImageLoadingBuilder? loadingBuilder,

  13. BlendMode? colorBlendMode,
  14. BoxFit? fit,
  15. AlignmentGeometry alignment = Alignment.center,
  16. ImageRepeat repeat = ImageRepeat.noRepeat,
  17. Rect? centerSlice,
  18. bool matchTextDirection = false,

  22. FilterQuality filterQuality = FilterQuality.low,
})

Creates a widget that displays an image.

To show an image from the network or from an asset bundle, consider using Image.network and Image.asset respectively.

The image, alignment, repeat, and matchTextDirection arguments must not be null.

Either the width and height arguments should be specified, or the widget should be placed in a context that sets tight layout constraints. Otherwise, the image dimensions will change as the image is loaded, which will result in ugly layout changes.

Use filterQuality to specify the rendering quality of the image.

If excludeFromSemantics is true, then semanticLabel will be ignored.
