Your dart-sdk resource is defined this way, which only takes care of macOS:

  # Determine architecture and set the Dart SDK resource accordingly
  dart_sdk_url, dart_sdk_sha = if Hardware::CPU.intel?
    ["https://storage.googleapis.com/dart-archive/channels/stable/release/3.2.6/sdk/dartsdk-macos-x64-release.zip",
     "97661f20230686381f4fc5b05a63c6b5d5abc9570bf93ad4e5fc09309cd98517"]
  elsif Hardware::CPU.arm?
    ["https://storage.googleapis.com/dart-archive/channels/stable/release/3.2.6/sdk/dartsdk-macos-arm64-release.zip",
     "2e04c91039f9cc05b2e93ce788aa1ce08bc4df5b50c84d6b4e21ba2b2538adb6"]
  end

  resource "dart-sdk" do
    url dart_sdk_url
    sha256 dart_sdk_sha
  end

You need to adjust the formula to make sure the resource works on Linux too. See rust.rb for example.
