Unable to compile on Arch Linux

[System64fumo]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When trying to build by following the tutorial i'm unable to run the dart run build_runner...
I get

Resolving dependencies in /tmp/spotube... 
Because spotube requires the Flutter SDK, version solving failed.

Flutter users should run `flutter pub get` instead of `dart pub get`.

Expected Behavior

Building succesfully

Steps to reproduce

1: git clone https://github.com/KRTirtho/spotube
2: cd spotube
3: cp .env.example .env (Then editing it)
4: flutter pub get && dart run build_runner build --delete-conflicting-outputs --enable-experiment=records,patterns

Operating System

Arch Linux

Spotube version

3.4.0

Installation source

Website (spotube.netlify.app) or (spotube.krtirtho.dev)

Additional information

I'm Trying to build it from source since there is no aarch64 binary available yet (at least in the releases section or AUR), And i've seen discussions about it before in previous threads this one
Thing is.. I can't even build it on my x86_64 system..
Surely i'm doing something wrong here since i never really compiled a flutter/dart program before.
Any help would be appreciated.
