// /// CupertinoButton(
// When a Cupertino component is provided with a `CupertinoDynamicColor`, either /// child: child,
// directly in its constructor, or from an [InheritedWidget] it depends on (for example, /// // CupertinoDynamicColor works out of box in a CupertinoButton.
// [DefaultTextStyle]), the component will automatically resolve the color by calling /// color: CupertinoDynamicColor.withBrightness(
// [CupertinoDynamicColor.resolve], using their own [BuildContext]. /// color: CupertinoColors.white,
// /// darkColor: CupertinoColors.black,
// When used outside of a Cupertino component, such color resolution will not happen /// ),
// automatically. It's essential to call [CupertinoDynamicColor.resolve] with the /// onPressed: () { },
// correct [BuildContext] before using the color to paint, in order to get the /// )
// desired effect. /// ```
/// {@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 sample}
/// 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 sample}
///
/// The following code samples demostrate 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),
/// )
