/// A [Color] subclass that represents a family of colors, and the currect effective
/// color in the color family.
///
/// When used as a regular color, [CupertinoDynamicColor] is equivalent to the
/// effective color (i.e. [CupertinoDynamicColor.value] will come from the effective
/// color), which is determined by the [BuildContext] it is last resolved against.
/// If it has never been resolved, the light, normal contrast, base elevation variant
/// [CupertinoDynamicColor.color] will be the default effective color.
///
/// Sometimes manually resolving a [CupertinoDynamicColor] is not necessary, because
/// the Cupertino Library provides built-in support for it.
///
/// ### Using [CupertinoDynamicColor] in a Cupertino widget
///
/// When a Cupertino widget is provided with a [CupertinoDynamicColor], either
/// directly in its constructor, or from an [InheritedWidget] it depends on (for example,
/// [DefaultTextStyle]), the widget will automatically resolve the color using
/// [CupertinoDynamicColor.resolve] against its own [BuildContext], on a best-effort
/// basis.
///
/// {@tool snippet}
/// By default a [CupertinoButton] has no background color. The following sample
/// code shows how to build a [CupertinoButton] that appears white in light mode,
/// and changes automatically to black in dark mode.
///
/// ```dart
/// CupertinoButton(
/// child: child,
/// // CupertinoDynamicColor works out of box in a CupertinoButton.
/// color: CupertinoDynamicColor.withBrightness(
/// color: CupertinoColors.white,
/// darkColor: CupertinoColors.black,
/// ),
/// onPressed: () { },
/// )
/// ```
/// {@end-tool}
///
/// ### Using a [CupertinoDynamicColor] from a [CupertinoTheme]
///
/// When referring to a [CupertinoTheme] color, generally the color will already
/// have adapted to the ambient [BuildContext], because [CupertinoTheme.of]
/// implicitly resolves all the colors used in the retrieved [CupertinoThemeData],
/// before returning it.
///
/// {@tool snippet}
/// The following code sample creates a [Container] with the `primaryColor` of the
/// current theme. If `primaryColor` is a [CupertinoDynamicColor], the container
/// will be adaptive, thanks to [CupertinoTheme.of]: it will switch to `primaryColor`'s
/// dark variant once dark mode is turned on, and turns to primaryColor`'s high
/// contrast variant when [MediaQueryData.highContrast] is requested in the ambient
/// [MediaQuery], etc.
///
/// ```dart
/// Container(
/// // Container is not a Cupertino widget, but CupertinoTheme.of implicitly
/// // resolves colors used in the retrieved CupertinoThemeData.
/// color: CupertinoTheme.of(context).primaryColor,
/// )
/// ```
/// {@end-tool}
///
/// ### Manually Resolving a [CupertinoDynamicColor]
///
/// When used to configure a non-Cupertino widget, or wrapped in an object opaque
/// to the receiving Cupertino component, a [CupertinoDynamicColor] may need to be
/// manually resolved using [CupertinoDynamicColor.resolve], before it can used
/// to paint. For example, to use a custom [Border] in a [CupertinoNavigationBar],
/// the colors used in the [Border] have to be resolved manually before being passed
/// to [CupertinoNavigationBar]'s constructor.
///
/// {@tool snippet}
///
/// The following code samples demonstrate two cases where you have to manually
/// resolve a [CupertinoDynamicColor].
///
/// ```dart
/// CupertinoNavigationBar(
/// // CupertinoNavigationBar does not know how to resolve colors used in
/// // a Border class.
/// border: Border(
/// bottom: BorderSide(
/// color: CupertinoDynamicColor.resolve(CupertinoColors.systemBlue, context),
/// ),
/// ),
/// )
/// ```
///
/// ```dart
/// Container(
/// // Container is not a Cupertino widget.
/// color: CupertinoDynamicColor.resolve(CupertinoColors.systemBlue, context),
/// )
/// ```
/// {@end-tool}
///
/// See also:
///
/// * [CupertinoUserInterfaceLevel], an [InheritedWidget] that may affect color
/// resolution of a [CupertinoDynamicColor].
/// * [CupertinoTheme.of], a static method that retrieves the ambient [CupertinoThemeData],
/// and then resolves [CupertinoDynamicColor]s used in the retrieved data.
