Error: Unable to create dart snapshot for flutter tool.

I wanted to update Flutter when I ran into this problem. And I can't run my project at all, as if Flutter was not installed at all

I want to be able to update and output

You were most probably looking at the source code of the http package the dart pub tool downloaded to your computer and accidentally pressed a d on your keyboard in AppData/Local/Pub/Cache/hosted/pub.dev/http-0.13.6/lib/src/base_request.dart on line 144 and this made the code incompilable. Go to this file and remove the d or run dart pub cache repair to redownload all the packages in your pub cache.

Try correcting the name to the name of an existing getter, or defining a getter or field named 'drethrow'.
      drethrow;
      ^^^^^^^^

The cause was clearly stated in the error you were getting.
