This PR fixes #92525 and introduces the following changes according to [latest iOS HIG](https://developer.apple.com/design/human-interface-guidelines/buttons#iOS-iPadOS): - `CupertinoButton` now has a `size` property (type `enum CupertinoButtonSize`, values sm/md/lg, default `lg`) that allows the devs to apply new iOS 15+ button styles - Previously `CupertinoButton` had a larger padding when no background color was specified. With the new HIG, that is no longer the case - `CupertinoButton` now has a `.tinted` constructor that renders a translucent background (transparency % is brightness-dependent) and uses a different foreground color compared to `.filled` - `CupertinoButton` now uses the `actionTextStyle` TextStyle from the given theme - `CupertinoButton`'s child IconTheme's size will always be x1.2 the given TextStyle's size - `CupertinoTextThemeData` now has a `actionSmallTextStyle` property to use with small buttons (including a default `_kDefaultActionSmallTextStyle` TextStyle) Preview & example:  > **NOTE**: there is a discrepancy in dark mode button foreground color between the default CupertinoTheme and the HIG. A separate issue will be opened for this. ~EDIT: issue reported here https://github.com/flutter/flutter/issues/152846~ EDIT2: fixed by #153039 !  ## Example ```dart import 'package:flutter/cupertino.dart'; const Widget body = Row( mainAxisSize: MainAxisSize.min, mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ Icon( CupertinoIcons.play_fill, ), Text("Play"), ], ); void main() => runApp( CupertinoApp( home: Container( child: Wrap( direction: Axis.horizontal, children: <Widget>[ // header Text(''), Text('Plain'), Text('Grey'), Text('Tinted'), Text('Filled'), // small Text('Small'), CupertinoButton( child: body, onPressed: () {}, size: CupertinoButtonSize.small, ), CupertinoButton.tinted( child: body, onPressed: () {}, size: CupertinoButtonSize.small, color: CupertinoColors.systemGrey, ), CupertinoButton.tinted( child: body, onPressed: () {}, size: CupertinoButtonSize.small, ), CupertinoButton.filled( child: body, onPressed: () {}, size: CupertinoButtonSize.small, ), // medium Text('Medium'), CupertinoButton( child: body, onPressed: () {}, size: CupertinoButtonSize.medium, ), CupertinoButton.tinted( child: body, onPressed: () {}, size: CupertinoButtonSize.medium, color: CupertinoColors.systemGrey, ), CupertinoButton.tinted( child: body, onPressed: () {}, size: CupertinoButtonSize.medium, ), CupertinoButton.filled( child: body, onPressed: () {}, size: CupertinoButtonSize.medium, ), // large Text('Large'), CupertinoButton( child: body, onPressed: () {}, size: CupertinoButtonSize.large, ), CupertinoButton.tinted( child: body, onPressed: () {}, color: CupertinoColors.systemGrey, size: CupertinoButtonSize.large, ), CupertinoButton.tinted( child: body, onPressed: () {}, size: CupertinoButtonSize.large, ), CupertinoButton.filled( child: body, onPressed: () {}, size: CupertinoButtonSize.large, ), ].map((Widget w) => SizedBox(width: 110, height: 70, child: Center(child: w))).toList(), ), ) ), ); ``` *List which issues are fixed by this PR.
