Image.memory constructor

Image.memory(Uint8List bytes, { Key key, double scale: 1.0, String semanticLabel, bool excludeFromSemantics: false, double width, double height, Color color, BlendMode colorBlendMode, BoxFit fit, AlignmentGeometry alignment: Alignment.center, ImageRepeat repeat: ImageRepeat.noRepeat, Rect centerSlice, bool matchTextDirection: false, bool gaplessPlayback: false })

Creates a widget that displays an ImageStream obtained from a Uint8List.

The bytes, scale, and repeat 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.

If excludeFromSemantics is true, then semanticLabel will be ignored.

Implementation

Image.memory(Uint8List bytes, {
  Key key,
  double scale = 1.0,
  this.semanticLabel,
  this.excludeFromSemantics = false,
  this.width,
  this.height,
  this.color,
  this.colorBlendMode,
  this.fit,
  this.alignment = Alignment.center,
  this.repeat = ImageRepeat.noRepeat,
  this.centerSlice,
  this.matchTextDirection = false,
  this.gaplessPlayback = false,
}) : image = new MemoryImage(bytes, scale: scale),
     assert(alignment != null),
     assert(repeat != null),
     assert(matchTextDirection != null),
     super(key: key);
