Methods

accept<T>(ElementVisitor<T> visitor) → T?

inherited
computeConstantValue() → DartObject?
Returns a representation of the value of this variable, forcing the value to be computed if it had not previously been computed, or null if either this variable was not declared with the 'const' modifier or if the value of this variable could not be computed because of errors.

Returns the presentation of this element as it should appear when presented to users.

getExtendedDisplayName(String? shortName) → String

inherited
isAccessibleIn(LibraryElement library) → bool
Whether the element, assuming that it is within scope, is accessible to code in the given library.

inherited
toString() → String
A string representation of this object.
inherited
