flutter 滑动关闭页面

设置主题为

 theme: new ThemeData(
        primarySwatch: Colors.blue,
        platform: TargetPlatform.iOS//添加这个属性即可
      ),

具体如下

void main() => runApp(new XxswApp());

class XxswApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: '小新书屋',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
        platform: TargetPlatform.iOS//添加这个属性即可
      ),
      home: new SplashPage(),
    );
  }
}
