Is the containsKey check needed here? Will the map return null if the key is not
present? Would it be equivalent and more efficient (only lookup key once instead
of twice) if  _decodeBool accepted jsonValue = "true", "false", null, and
returned true/false/null and the caller checked for a null return value if the
caller cared to do so? If yes then this could be rewritten as

bool enableAsync = _decodeBool(jsonPath + ".enableAsync", json["enableAsync"]);

and if enableAsync was required it would read

bool enableAsync = _decodeBool(jsonPath + ".enableAsync", json["enableAsync"]);
if (enableAsync == null) {
   missingKey(jsonPath, "enableAsync");
}

[Paul Berry, 2014/08/18 21:58:03]

That suggestion would create a semantic difference: { "enableAsync": null }
would be treated as equivalent to the "enableAsync" key being absent.  That's ok
for bools, because a bool can never be null.  But we've already decided (for
better compatibility with Lisp) that the client is allowed to replace empty
lists and maps with null.  That means that for an optional list or an optional
map, there would be an ambiguity: does { "foo": null } mean that the optional
field "foo" is absent, or that the optional field "foo" is an empty list/map? 
I'd rather avoid that ambiguity.

However, I agree that it's problematic to look up each key in the map twice
(once in the .containsKey() call and once in the use of operator[]).  What would
you think about something like this as an alternative?
