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.
