未处理的异常：FormatException：意外的字符（在字符1），API

Question

我试图使用HTTP软件包将Flutter应用连接到MySQL。但是当我想要解码JSON时出现错误。但是，如果我打印不带List的JSON，则会出现问题。

import 'dart:convert';

import 'package:foodapps/src/models/food_model.dart';
import 'package:scoped_model/scoped_model.dart';
import 'package:http/http.dart' as http;

class FoodModel extends Model{
  List<Food> _foods = [];

  List<Food> get foods{
    return List.from(_foods);
  }

  void addFood(Food food){
    _foods.add(food);
  }

  void fetchFoods(){
    http
        .get("http://192.168.100.9/flutter_foodapps/api/foods/getfoods.php")
        .then((http.Response response){
       final List fetchedData = json.decode(response.body);
       print(fetchedData);
      
    });

  }
}
