如何解决“在 Flutter SDK 中找不到 package integration_test”错误

Question

I have an app, it is very simple and I keep getting this error:

pub get failed (server unavailable) -- attempting retry 1 in 1 second... Because bascis depends on integration_test any from sdk which doesn't exist (could not find package integration_test in the Flutter SDK), version solving failed.

I have tried

Pup upgrade, Pub get.

How can I get rid of this error?

Answer 1

I had the same error after changing my channel from master to stable. I was able to fix it by removing (or commenting out) the following library from pubspec.yaml

dev_dependencies:
#  integration_test:
#    sdk: flutter

Answer 2

I experienced this when I was trying to setup a flutter web project without enabling flutter web on my PC. I enabled flutter for web and everything was okay.

Answer 3

For me had to comment out sdk part like so:

dev_dependencies:
  integration_test:
   # sdk: flutter

Answer 4

It is likely due to your.network problem. Because the output says (server unavailable) .

Ways to debug this:

1. Try curl https://google.com to see whether your command line can connect to.network.
2. Also try, for example, curl https://flutter.dev (or, try to curl the actual url your pub get is trying to access.

This may due to, for example, your.network is broken. Or because you have a broken VPN, broken proxy, etc.
