bad import of http on flutter for web

Question

i was attempting to make an http request to a server, but when i import the package http the vs code print the next error:

Unable to find modules for some sources, this is usually the result of either a
bad import, a missing dependency in a package (or possibly a dev_dependency
needs to move to a real dependency), or a build failure (if importing a
generated file).

Please check the following imports:

`import 'package:http/http.dart' as http;` from fcfm_pa|lib/src/pages/registro_page.dart at 5:1

someone knows what's happen?

Answer 1

You should update your pubspec.yaml file with the following library declaration:

dependencies:
  http: ^0.12.0+4

and then import the library. After doing so, make sure to do over the terminal:

flutter pub get

and maybe even flutter clean to make sure you have everything correctly. Make a new build and you should be good to go.

If you are on beta channel, this is an issue that occurs.

Try flutter channel master and then run the app again, this issue should not appear anymore.
