shownVariables property
The set of variable names (without $) that may be accessed from the
forwarded module.
If this is empty, no variables may be accessed. If it's null, it imposes
no restrictions on which variables may be accessed.
If this is non-null, hiddenMixinsAndFunctions and hiddenVariables
are guaranteed to both be null and shownMixinsAndFunctions is
guaranteed to be non-null.
Implementation
final Set<String>? shownVariables;
