isMap property Null safety

bool isMap

Return true if this literal represents a map literal.

This getter will always return false if isSet returns true.

However, this getter is not the inverse of isSet. It is possible for both getters to return false if

  • the AST has not been resolved (because determining the kind of the literal is done during resolution),
  • the literal is ambiguous (contains one or more spread elements and none of those elements can be used to determine the kind of the literal), or
  • the literal is invalid because it contains both expressions (for sets) and map entries (for maps).

In both of the latter two cases there will be compilation errors associated with the literal.
