I am not able to use flutter as im getting an error with the dart sdk, only it has been working for weeks until today

Question

I am currently having this issue and can't find any solutions that work. Yesterday It was running fine and this afternoon when I wanted to code I received this message in the terminal.

flutter run... Downloading Dart SDK from Flutter engine <<<<<<< HEAD 07c1eed46b9d9b58df78566e9b8b2e42e80d3380 92ae191c17a53144bf4d62f3863c110be08e3fd3

I am not using a VPN, am not from china, and as I said this was running yesterday. I have tried reinstalling the flutter package, tried redirecting to redoing the path in Linux, also tried to just clone the github/flutter repo but nothing. Please help

Answer 1

Found that there was an issue with a file in flutter/bin/internal called engine.version that had the same text as the "head" issue as mentioned in the error code. I have replaced the file with the one from the flutter GitHub repo and the error has gone. will close the issue.
