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() {
var s = 'SeekFlag(';
if (test(from0)) s += '+from0';
if (test(fromStart)) s += '+fromStart';
if (test(fromNow)) s += '+fromNow';
if (test(frame)) s += '+frame';
if (test(keyFrame)) s += '+keyFrame';
if (test(inCache)) s += '+inCache';
return '$s)';
}
