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() {
if (isEmpty) {
return '';
}
final state_entries = _state.entries;
var state = '${state_entries.first.key}=${state_entries.first.value}';
state_entries.skip(1).forEach((entry) {
state += ',${entry.key}=${entry.value}';
});
return state;
}
