Visual Studio Code - URI Target Does Not Exist 'package: flutter / material.dart'

Question

I just installed my Macbook for flutter development,

So I downloaded the flutter SDK and put it in my documents . After that, I configure the path variable to work with flutter on my command line.

I execute a command flutter create todolistto achieve an empty project.

I also tweaked my Visual Studio code with Dart-Code so that I had the correct syntax highlighting, intellisense, etc.

Therefore, when I open the Visual Studio code, it highlights the method import, as shown in the following figure:
