如何用GridView --Flutter从服务器端放入JSON数据

dependencies:
  http: ^0.13.3

import 'package:http/http.dart' as http;

Future<List<dynamic>> fetchJSONData() async {
  final response = await http.get(Uri.parse('服务器端URL'));
  if (response.statusCode == 200) {
    return json.decode(response.body);
  } else {
    throw Exception('Failed to load JSON data');
  }
}

GridView.builder(
  gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
    crossAxisCount: 2, // 每行显示的网格数量
    crossAxisSpacing: 10, // 网格之间的水平间距
    mainAxisSpacing: 10, // 网格之间的垂直间距
  ),
  itemCount: jsonData.length, // 网格项的数量
  itemBuilder: (BuildContext context, int index) {
    return GridTile(
      child: Container(
        // 网格项的内容
        child: Text(jsonData[index]['data']),
      ),
    );
  },
)
