Так что это мой полный код. Он относительно короткий, потому что я просто пытаюсь получить заголовок видео и идентификатор видео из invidiou. sh api: 'https://invidiou.sh/api/v1/search?q=Corridor+Crew'
import 'dart:async';
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
Future<Album> fetchAlbum() async {
final response =
await http.get('https://invidiou.sh/api/v1/search?q=Corridor+Crew');
if (response.statusCode == 200) {
// If the server did return a 200 OK response, then parse the JSON.
return Album.fromJson(json.decode(response.body));
} else {
// If the server did not return a 200 OK response, then throw an exception.
throw Exception('Failed to load album');
}
}
class Album {
final String videoId;
final String title;
Album({this.videoId, this.title});
factory Album.fromJson(Map<String, dynamic> json) {
return Album(
videoId: json['videoId'],
title: json['title'],

Следующее исключение

встречается здесь в response.body, и я не знаю, что с этим делать:
Future<Album> fetchAlbum() async {
final response =
await http.get('https://invidiou.sh/api/v1/search?q=Corridor+Crew');
if (response.statusCode == 200) {
// If the server did return a 200 OK response, then parse the JSON.
return Album.fromJson(json.decode(response.body)); <---- HERE!
} else {
// If the server did not return a 200 OK response, then throw an exception.
throw Exception('Failed to load album');
}
