如何设置容器在GridView.builder内部的固定高度？不应依赖于childAspectRatio

Container(
  height: 200, // 设置容器的固定高度
  child: GridView.builder(
    itemCount: itemCount,
    gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
      crossAxisCount: crossAxisCount,
      childAspectRatio: aspectRatio,
    ),
    itemBuilder: (context, index) {
      return YourWidget();
    },
  ),
),

SizedBox(
  height: 200, // 设置SizedBox的固定高度
  child: GridView.builder(
    itemCount: itemCount,
    gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
      crossAxisCount: crossAxisCount,
      childAspectRatio: aspectRatio,
    ),
    itemBuilder: (context, index) {
      return YourWidget();
    },
  ),
),
