如何将List <Int>绑定到gridview？

import 'package:flutter/material.dart';

class MyGridView extends StatefulWidget {
  @override
  _MyGridViewState createState() => _MyGridViewState();
}

class _MyGridViewState extends State<MyGridView> {
  List<int> list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('GridView Example')),
      body: GridView.builder(
        itemCount: list.length,
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 3,
          crossAxisSpacing: 10,
          mainAxisSpacing: 10,
        ),
        itemBuilder: (BuildContext context, int index) {
          return GridTile(
            child: Card(
              child: Center(child: Text(list[index].toString())),
            ),
          );
        },
      ),
    );
  }
}
