Flutter upgrade error - Can't load Kernel binary: Invalid kernel binary format version.

[Wesley Aoyama]

Hello,

I'm trying to upgrade flutter version 2.2.3 to 2.5.3, but when I run flutter upgrade, the following error appears:

 d:\src\flutter> flutter upgrade --force

Upgrading Flutter to 2.5.3 from 2.2.3 in D:\correios\ambiente\flutter...

Checking Dart SDK version...

Downloading Dart SDK from Flutter engine d3ea636dc5d16b56819f3266241e1f708979c233...

Expanding downloaded archive...

Running pub upgrade...

Can't load Kernel binary: Invalid kernel binary format version.

It's not a network problem, because it downloads the dart-sdk zip file, extracts it, and when it does pub upgrade, it craches.

I'm stuck on this for more than 3 days. I've already tryied to delete the bin/cache folder, run flutter doctor, but then other error appears.

 d:\src\flutter> flutter doctor

Checking Dart SDK version...

Downloading Dart SDK from Flutter engine ...

Building flutter tool...

Running pub upgrade...

Error: Error when reading '/bin/cache/flutter_tools.snapshot': O sistema não pode encontrar o arquivo especificado.

 

When I just install flutter and runs flutter doctor, it complains of Visual Studio, but I don't think it's a problem, because I only use android studio and develop mobile apps.
