.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I am very new to Flutter, and stuck at the following error:
package:http/http.dart That library is in a package that is not known. Maybe you forgot to mention it in your pubspec.yaml file?

Please help in resolving this error.

that package is part of flutter and should not show an error if you import it. To help you, you should post your relevant parts of the pubspec.yaml and .dart-File

The package is not a part of flutter but it is distributed via pub.

please google this before putting it up here, just search http/http.dart, you will get dartlang packages page(pub.dartlang.org/packages/http). the documentation and usage is pretty detailed.

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'

I had the same problem. You just have to add latest http dependencies in pubspec.yaml

Here is the full code,

  dependencies:

      flutter:

        sdk: flutter



      http: ^0.12.0+1



      # The following adds the Cupertino Icons font to your application.

      # Use with the CupertinoIcons class for iOS style icons.

      cupertino_icons: ^0.1.2

Don't forget to change verson no. of http
To check latest version of http click here

If you are running app directly from command line then you could also do:

with Flutter:

$ flutter packages get

with pub:

$ pub get
