Gridview.builder 在 Flutter 中不接受 List<widget>

Question

我无法在 Gridview.builder 中显示列表。

List<Widget> booksList = [];

return new GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 3,
          mainAxisSpacing: 10,
          crossAxisSpacing: 10,
        ),
        itemCount: libraryList.length,
        itemBuilder: (BuildContext ctx, index) {
          return booksList;
          );
        }); 

它返回错误“返回类型 'List' 不是 'Widget'，正如闭包上下文所要求的那样。”我被困在如何继续。

List<Widget> booksList = [
Text('Hello'),
Text('World')];

return GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 3,
          mainAxisSpacing: 10,
          crossAxisSpacing: 10,
        ),
        itemCount: libraryList.length,
        itemBuilder: (BuildContext ctx, index) {
          return booksList[index];
          );
        });
