Image.memory constructor

Image.memory(Uint8List bytes, { Key key, double scale: 1.0, 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.

Implementation

Image.memory(Uint8List bytes, {
  Key key,
  double scale: 1.0,
  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);
