#17637 updates Checkbox, Radio, and Switch to use the ThemeData toggleableActiveColor. If you are using a light theme and are not specifying an accentColor in your ThemeData, these controls will now use a higher contrast shade from the primary swatch.

#17586 added a new background property to TextStyle. Subclasses must ensure that this property is handled in constructors and copyWith.

v0.4.0

#17021 added implicit a11y scrolling for iOS. For this, viewports define a cache extend before the leading as well as after the trailing edge and slivers are expected to provide semantics information if they fall into the cache extent.
