toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() =>
    // Try to use the identifier's original lexeme to preserve any escape
    // codes as authored. The name, which may include escaped values, may no
    // longer be a valid identifier.
    span?.text ?? name;
