createLocalPictureConfiguration function

PictureConfiguration createLocalPictureConfiguration(BuildContext? context, { Rect? viewBox, ColorFilter? colorFilterOverride, Color? color, BlendMode? colorBlendMode, })

Creates an PictureConfiguration based on the given BuildContext (and optionally size).

This is the object that must be passed to PictureProvider.resolve.

If this is not called from a build method, then it should be reinvoked whenever the dependencies change, e.g. by calling it from State.didChangeDependencies, so that any changes in the environment are picked up (e.g. if the device pixel ratio changes).

• PictureProvider, which has an example showing how this might be used.

Implementation

PictureConfiguration createLocalPictureConfiguration(
  BuildContext? context, {
  Rect? viewBox,
  ColorFilter? colorFilterOverride,
  Color? color,
  BlendMode? colorBlendMode,
}) {
  ColorFilter? filter = colorFilterOverride;
  if (filter == null && color != null) {
    filter = ColorFilter.mode(color, colorBlendMode ?? BlendMode.srcIn);
  }
  return PictureConfiguration(
    bundle: context != null ? DefaultAssetBundle.of(context) : rootBundle,
    locale: context != null ? Localizations.maybeLocaleOf(context) : null,
    textDirection: context != null ? Directionality.maybeOf(context) : null,
    viewBox: viewBox,
    platform: defaultTargetPlatform,
    colorFilter: filter,
  );
