In Flutter "final response = await http.get(url);" I am getting an error in the url part of the code

Question

I am getting an error in the url part of the code, I have shown the error in the screenshot. How can I fix my code without changing its function.

error message

Future<List<Articles>?> getNews() async {

String url = "https://jsonplaceholder.typicode.com/posts";
final response = await http.get(url);

if (response.body.isEmpty) {
  final responseJson = json.decode(response.body);
  News news = News.fromJson(responseJson);
  return news.articles;
}
return null;}

You need to pass Uri instead of string.

 final response = await http.get(Uri.parse(url));

I am facing this kind of issue, could it be related to your solution elsewhere? [error][1] [1]: https://i.stack.imgur.com/3ZuSI.png – Serdar Bilgili Jul 29 '22 at 20:35
That is related to null safety issue, do a null check and provide string – Md. Yeasin Sheikh Jul 29 '22 at 20:42
I did, but I still get a warning. [code](https://i.stack.imgur.com/9vZPU.png) – Serdar Bilgili Jul 29 '22 at 20:50
I need to check more code, you can create separate question with providing necessary snippet? And avoid pasting code-image, provide code-snippet that will reproduce the issue. – Md. Yeasin Sheikh Jul 29 '22 at 21:01
Btw, does this one solve your question issue? – Md. Yeasin Sheikh Jul 29 '22 at 21:02
Sorry, I didn't understand what to do. – Serdar Bilgili Jul 29 '22 at 21:08
About current question or new? About URL issue, do as I've answered. And the new one will be `if(articles[index].urlImage!=null)Image.network(articles[index].urlToImage)` – Md. Yeasin Sheikh Jul 29 '22 at 21:11
If the solution is like this, this also gives an error [error](https://i.stack.imgur.com/eTLLy.png) – Serdar Bilgili Jul 29 '22 at 21:15
Oh forgot to add `!`, do `if(articles[index].urlImage!=null)Image.network(articles[index].urlToImage!)` Check more [here](https://dart.dev/null-safety/understanding-null-safety) – Md. Yeasin Sheikh Jul 29 '22 at 21:16
(if(articles[index].urlImage!=null)) gives an error in the urlImage part in this section and corrects it as urlToImage. There is no problem in this part, but this time my code does not work. Normally, it should pull images from the API service. – Serdar Bilgili Jul 29 '22 at 21:35
Can you debug the app if you are getting data or not. else you can [ask](https://stackoverflow.com/questions/ask) a different question providing the necessary snippet that will reproduce the issue – Md. Yeasin Sheikh Jul 29 '22 at 21:43
I guess it can't access the data. [debug](https://imgur.com/Q7Brnk8) – Serdar Bilgili Jul 29 '22 at 21:57

I think this answers deserve to be accepted before jumping into another question... – Gemark Almacen Feb 03 '23 at 03:10

You can assign uri something like this

var uri= Uri.https('jsonplaceholder.typicode.com', 'posts');

And if you want to add queryparametrs then use below code

final queryParameters =
    {
      'key' : 'value',
    };
    var uri= Uri.https('jsonplaceholder.typicode.com', 'posts',queryParameters);

And use this uri in place of Url.

final response = await http.get(uri);

In Flutter "final response = await http.get(url);" I am getting an error in the url part of the code
