I use Android Studio as my IDE in coding Flutter. I was able to create 2 projects before this and it worked absolutely fine. I had to clone a repo from Github. The IDE said
This seems to be the problem:

Since you said that you added the Android SDK to your D directory, you could just add D:\Android\sdk\tools and D:\Android\sdk\platform-tools to your PATH environment variable. This is how you can add it to your Path enviroment variable: https://docs.telerik.com/teststudio/features/test-runners/add-path-environment-variables
