我需要帮助解决这个错误。所以我在youtube上看了这个教程，时间是2:40到8:01。我得到的错误是这个
The argument type 'String' can't be assigned to the parameter type 'Uri'.dart(argument_type_not_assignable)
这是我的代码(代码与教程相同，只是链接不同(
import 'dart:convert';
import 'package:xml2json/xml2json.dart';
import 'package:http/http.dart' as http;
Future<List> rssToJson(String category,
{String baseUrl = 'https://www.cnnindonesia.com/nasional/rss'}) async {
var client = http.Client();
final myTranformer = Xml2Json();
return await client.get(baseUrl + category + '/rssfeed.xml').then((Response) {
return Response.body;
}).then((bodyString) {
myTranformer.parse(bodyString);
var json = myTranformer.toGData();
return jsonDecode(json)['rss']['channel']['item'];
});
}
代码上有一条红色下划线
return await client.get(baseUrl + category + '/rssfeed.xml').then((Response)
这是我的pubspec.yaml

# The following line prevents the package from being accidentally published to

publish_to: 'none' # Remove this line if you wish to publish to pub.dev
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
assets:
- assets/icons/
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:
- family: Times
fonts:
- asset: assets/fonts/times_news_roman/Times New Roman 400.ttf
weight: 400
- asset: assets/fonts/times_news_roman/Times New Roman Gras 700.ttf
weight: 700
- family: Avenir
fonts:
- asset: assets/fonts/avenir/AvenirNextLTPro-Regular.otf
weight: 400
- asset: assets/fonts/avenir/AvenirNextLTPro-Demi.otf
weight: 500
- asset: assets/fonts/avenir/AvenirNextLTPro-Demi.otf

目前，我使用的是Flutter SDK的新版本，2.10.1版本。请帮帮我。我需要尽快得到解决方案。谢谢

client.get((方法需要一个Uri，而您正在其中传递字符串
client.get(Uri.parse(baseUrl + category + '/rssfeed.xml'))
