toString method
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() {
return 'ColumnHeader(empty: $empty, text: $text, alignment: $alignment, textAlign: $textAlign, showMenu: $showMenu, textStyle: $textStyle, backgroundColor: $backgroundColor, foregroundColor: $foregroundColor)';
}
