Added in main.dart

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

And in pubspec.yaml

  • dependencies:

    • flutter:
    sdk: flutter
    http: ^0.12.0+2

    But DartAnalysis: write

    error: Target of URI doesn't exist: 'package:http/http.dart'. (uri_does_not_exist at [network_terminal] lib/main.dart:2)

    Then I try

    Terminal:$ flutter packages get

    DartAnalysis:

    Running "flutter packages get" in network_terminal...
    Error on line 21, column 5 of pubspec.yaml: A dependency may only have one source.
    ╷
    21 │ ┌ sdk: flutter

    23 │ │ # The following adds the Cupertino Icons font to your application.
    24 │ │ # Use with the CupertinoIcons class for iOS style icons.
    25 │ │ cupertino_icons: ^0.1.2
    │ └──^
    ╵
    pub get failed (65)

    Then try

    Terminal:$ flutter packages upgrade

    DartAnalysis:

    Running "flutter packages upgrade" in network_terminal...
    Error on line 21, column 5 of pubspec.yaml: A dependency may only have one source.

    ╷

    I don’t understand, how to move on

    Terminal:$ flutter doctor

    Go to your pubspec.yaml file , and add the http dependency:

    dependencies:
flutter:
sdk: flutter

cupertino_icons: ^0.1.2
http: any

    Remember, the indentation must be the same as ‘flutter’ or ‘cupertino_icons’
    And don’t forget to run this command in your terminal :

    flutter packages get
