动态获取GridView.builder中项目的高度

GridView.builder(
  gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
    crossAxisCount: 2,
  ),
  itemCount: itemCount,
  itemBuilder: (context, index) {
    return LayoutBuilder(
      builder: (BuildContext context, BoxConstraints constraints) {
        double itemHeight = constraints.maxHeight;
        double itemWidth = constraints.maxWidth;

        // 在这里根据具体的项目内容和布局来计算高度

        return Container(
          height: itemHeight,
          width: itemWidth,
          // 项目内容和布局
        );
      },
    );
  },
);
