使用 ThemeData 作为 CupertinoApp 的主题

boo*_*boy 2 themes widget ios flutter flutter-cupertino

我的应用程序是使用 aMaterialApp作为根小部件构建的。对于这个材质应用,我添加了一个主题如下:

MaterialApp(
  theme: myTheme,
  home: MyHomePage(),
  ...
)

final ThemeData myTheme = _buildTheme();

ThemeData _buildTheme() {
  final ThemeData base = ThemeData.light();
  return base.copyWith(
    ...
      textTheme: _buildMyTextTheme(base.textTheme),
      primaryTextTheme: _buildMyTextTheme(base.primaryTextTheme),
      accentTextTheme: _buildMyTextTheme(base.accentTextTheme),
      pageTransitionsTheme: PageTransitionsTheme(builders: {
        TargetPlatform.iOS: CupertinoPageTransitionsBuilder(),
      }));
}

TextTheme _buildMyTextTheme(TextTheme base) {
  return base
      .copyWith(
        headline:
            base.headline.copyWith(fontSize: 20.0, fontWeight: FontWeight.w500),
        title: base.title.copyWith(fontSize: 18.0, fontWeight: FontWeight.w400),
        subhead:
            base.subhead.copyWith(fontSize: 16.0, fontWeight: FontWeight.w400),
        body1: base.body1.copyWith(fontSize: 14.0, fontWeight: FontWeight.w400),
        body2: base.body2.copyWith(fontSize: 14.0, fontWeight: FontWeight.w500),
        caption: base.caption.copyWith(
          fontWeight: FontWeight.w400,
          fontSize: 12.0,
        ),
      )
      .apply(
        fontFamily: 'myfont',
        displayColor: Colors.black,
        bodyColor: Colors.black,
      );
}

我曾经Theme.of(context.textTheme在整个应用程序中设置小部件树中的文本样式。

例如:我使用的标题

Text('Title', style:Theme.of(context).textTheme.title),

我使用的副标题

Text('Title', style:Theme.of(context).textTheme.subhead),

它按预期工作。但是现在我想使用一个CupertinoApp如果当前平台是 ios 因为它提供了原生 ios 感觉就像

  • 项目清单
  • 页面将通过向后滑动关闭。滚动过四肢将触发 iOS 风格的弹簧过度滚动。

我应该如何添加应用相同文本主题的 CupertionApp?

你可以CupertinoAppTheme小部件包装:

Theme(
   data: yourThemeData(), //your theme data here
   child: CupertinoApp(...),
);
