matchTextDirection property
Whether to paint the image in the direction of the TextDirection.
If this is true, then in TextDirection.ltr contexts, the image will be drawn with its origin in the top left (the "normal" painting direction for assetFlag); and in TextDirection.rtl contexts, the image will be drawn with a scaling factor of -1 in the horizontal direction so that the origin is in the top right.
This is occasionally used with assetFlag in right-to-left environments, for assetFlag that were designed for left-to-right locales. Be careful, when using this, to not flip assetFlag with integral shadows, text, or other effects that will look incorrect when flipped.
If this is true, there must be an ambient Directionality widget in scope.
Implementation
final bool matchTextDirection;
