Using an api and http request in Flutter

Question

    import 'dart:convert';
    import 'package:http/http.dart' as http;
    import 'package:newsapi_project/artical.dart';
    
    
    class News{ 
      List<ArticalModel> news =[];
      Future<void> getNews()async{
       String url="https://newsapi.org/v2/top-headlines?sources=techcrunch&apiKey=8efc3612216c44ccba7a8251dfbed587";
       var response=await http.get( url); //here its throwing the error//
       var jsonData= jsonDecode(response.body);
       if (jsonData["status"]=="ok"){
         jsonData["articles"].forEach(element){ //=> and even to in .forEach//
           if(element["urlToImagel"] != null && element["description"] != null ){
    
             ArticalModel articalmodel = ArticalModel(
               title:element["title"],
               author:element["author"],
               description:element["description"],
               url:element["url"],
              urlToImage:element["urlToImage"],
              content:element["content"]
             );
             news.add(articalmodel);
           }
         };
       }
      }
    
    }

 The argument type 'String' can't be assigned to the parameter type 'Uri'.dart

   var response=await http.get( url); // this is where I am getting error

  Function expressions can't be named Try removing the name, or moving the function expression to a function declaration statement.
 .forEach  this is where I am getting error

Expected an identifier.
.forEach  this is where I am getting error

How can I solve this?

Solution

Try below code hope its help to you. Change your API url declaration.

String url = 'https://newsapi.org/v2/top-headlines?sources=techcrunch&apiKey=8efc3612216c44ccba7a8251dfbed587';

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

var = response = await http.get(Uri.parse(url)); should work.

[Ameer Hamza]

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

For future reference, be sure to have a .fromJson() constructor and a .toJson() functions for your JSON objects represented in Dart.
