/// [SingletonFlutterWindow] that wraps another [SingletonFlutterWindow] and
/// allows faking of some properties for testing purposes.
///
/// Tests for certain widgets, e.g., [MaterialApp], might require faking certain
/// properties of a [SingletonFlutterWindow]. [TestWindow] facilitates the
/// faking of these properties by overriding the properties of a real
/// [SingletonFlutterWindow] with desired fake values. The binding used within
/// tests, [TestWidgetsFlutterBinding], contains a [TestWindow] that is used by
/// all tests.
///
/// ## Sample Code
///
/// A test can utilize a [TestWindow] in the following way:
///
/// ```dart
/// testWidgets('your test name here', (WidgetTester tester) async {
/// // Retrieve the TestWidgetsFlutterBinding.
/// final TestWidgetsFlutterBinding testBinding = tester.binding;
///
/// // Fake the desired properties of the TestWindow. All code running
/// // within this test will perceive the following fake text scale
/// // factor as the real text scale factor of the window.
/// testBinding.window.textScaleFactorFakeValue = 2.5;
///
/// // Test code that depends on text scale factor here.
/// });
/// ```
///
/// The [TestWidgetsFlutterBinding] is recreated for each test and
/// therefore any fake values defined in one test will not persist
/// to the next.
///
/// If a test needs to override a real [SingletonFlutterWindow] property and
/// then later return to using the real [SingletonFlutterWindow] property,
/// [TestWindow] provides methods to clear each individual test value, e.g.,
/// [clearLocaleTestValue()].
///
/// To clear all fake test values in a [TestWindow], consider using
/// [clearAllTestValues()].
///
/// See also:
/// Test version of [AccessibilityFeatures] in which specific features may
/// be set to arbitrary values.

/// testing purposes and is used by the [platformDispatcher] property of
