 > GridView.builder
 按需创建组件，跟custom差不多，但增加itemCount来限制加载子组件最大值，itemCount取代childrenDelegate来动态创建组件。
 - itemCount： 子组件最大数量，默认没有限制。效果跟GridView.custom一致
 - gridDelegate：设置布局，单行最大布局数量或单列单项最大长度，参考GridView.custom
 - itemBuilder：子组件动态加载回调方法，长度受itemCount值影响，itemCount不为0且存在时，数量需小于itemCount值
-
 	```
 	GridView.builder(
-      itemCount: 31,
-      gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
-        crossAxisCount: 3, // 单行最大数量值
-      ),
-      itemBuilder: (context, index) {
-        print('index $index');
-        return Center(
-          child: Text('index $index'),
-        );
-      },
-    ),

+					child: Text('index $index'),
