Flutter | Dart : Target of URI does not exist

I am making my first Application to build an Android App with Flutter. I am using Android Studio as IDE. The problem is when I import the http package:

 import 'package:http/http.dart' as http;

I get an error :

error: Target of URI doesn't exist: 'package:http/http.dart'. (uri_does_not_exist at [flutter_crypto] lib\home_page.dart:3)

That's my code :

  Future<List> getCurrencies() async{
    String cryptoUrl = "https://api.coinmarketcap.com/v1/ticker/?limit=50";
    http.Response response = await http.get(cryptoUrl);
    return JSON.decode(response.body);
  }

Thanks,

Make sure you have added the dependency to pubspec.yaml

dependencies:
  http: ^0.12.0

You will also need to:

flutter packages get

For any upcoming problem with importing packages from dart please go to official Dart website packages and search for needed package and you will find solution up there.

for your issue go to:

  3. follow guide steps:

    In pubspec.yaml file:@ dependencies

You need to add the HTTP dependency to pubspec.yaml as per below.

 dependencies:
      flutter:
        sdk: flutter

      # The following adds the Cupertino Icons font to your application.
      # Use with the CupertinoIcons class for iOS style icons.
      cupertino_icons: ^0.1.2
      http: ^0.12.0

With the dependency added you then need to run the following command to update/install required packages:

flutter packages upgrade

Hope this helps
