Temporarily Exclude DTMF Library

[eopeter]

@cybex-dev you said "Regarding flutter_dtmf, it seems Web has a bit of a problem when including the library - you may have noticed it's disabled temporarily until a fix has been added."

[eopeter]

Can we exclude it just for web to publish the latest version or wait for the fix?

Hi @eopeter, I believe we can though it seems simply including the flutter_dtml package in pubspec.yaml seems to cause this issue (atleast on Web).

Further, it seems there is also another issue with regards to grabbing the AudioContext window object, the error I do not recall but has been a bit of a challenge to resolved.

I'll be looking at resolving this weekend for a release next week.
