当我想新建一个flutter项目时，flutter只是回到了欢迎界面

Question

I have already installed Flutter and Dart plugins in Android Studio. I go through all the stages of creating a Flutter project but when I click on Finish I get the dialog "creating a new flutter project" but after a few seconds the welcome screen keeps showing up and I'm back at square one. Can anyone help, please?

Here's the information of "flutter doctor -v" command:

Answer 1

It seems that you have a problem with Flutter installation. You can try to reinstall it (make sure you get version for your OS). The second problem is with Android SDK. Installing Android Studio is not enough. Try going through this setup instructions: https://flutter.dev/docs/get-started/install#android-setup .
