Description:
When running `dartfmt`, the error `/usr/bin/dartfmt: line 51: syntax error: unexpected end of file` occurs

Redownloading the package shows that dartfmt appears to be incomplete:

The version downloaded from dart's web site doesn't seem to have this issue. It appears that the last two lines were truncated in the Arch version.
