Flutter 滑动组件互相嵌套问题

滑动组件互相嵌套问题

• 如果listview/singlechildscrollview 嵌套gridview，将两个组件的shrinkwrap设置为true，并且gridview无法滚动 physics: new NeverScrollableScrollPhysics()。比如

return SingleChildScrollView(
        child: Column(crossAxisAlignment: CrossAxisAlignment.center, children: [
      GridView.builder(
          itemCount: 4,
          physics: NeverScrollableScrollPhysics(),
          shrinkWrap: true,
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
              crossAxisCount: 2,
              mainAxisExtent: 55,
              mainAxisSpacing: 15,
              crossAxisSpacing: 15),
          itemBuilder: (context, index) {
            return Container();
          }),
    ]));

• 由于SingleChildScrollView无shrinkWrap属性则不设置
