Flutter ---- 滚动控件去除默认阴影

方法1:
The following ScrollBehavior will remove the glow effect entirely :

class MyBehavior extends ScrollBehavior {
  @override
  Widget buildViewportChrome(
      BuildContext context, Widget child, AxisDirection axisDirection) {
    return child;
  }
}

To remove the glow on the whole application, you can add it right under MaterialApp :

MaterialApp(
  builder: (context, child) {
    return ScrollConfiguration(
      behavior: MyBehavior(),
      child: child,
    );
  },
  home: new MyHomePage(),
);

To remove it on a specific ListView, instead wrap only the desired ListView :

ScrollConfiguration(
  behavior: MyBehavior(),
  child: ListView(
    ...
  ),
)

方法2:推荐

NotificationListener<OverscrollIndicatorNotification>(
    onNotification: (OverscrollIndicatorNotification? overscroll) {
      overscroll!.disallowGlow();
      return true;
    },
  child: child,
),
