ansi_up 2.1.0

Minimal package containing 'ansi_up' third_party dependency used by package:devtools.

2.1.0

• Discontinue the ansi_up package.

2.0.0

• Fixed a regexp getting recompiled every time an AnsiUp is instantiated and decodeAnsiColorEscapeCodes is called for the first time.

  The regexp is now compiled once during the lifetime of the program.

• Removed AnsiUp.ansiColors and AnsiUp.palette256 members.

  These members were not useful to users, and they didn't need to be instance members. ansiColors is not a constant, and palette256 is now initialized only once (instead of every time an AnsiUp is initialized).

1.0.0

• Migrate to null safety.

0.0.2

• Implemented decodeAnsiColorEscapeCodes in Dart - now no longer using JS interop.
