toString method
override
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 'vicinity=$vicinity; '
'layoutOffset=$layoutOffset; '
'paintOffset=$paintOffset; '
'${_paintExtent == null
? 'not visible; '
: '${!isVisible ? 'not ' : ''}visible - paintExtent=$_paintExtent; '}'
'${keepAlive ? "keepAlive; " : ""}';
}
