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 'ChartConfig('
'title: $title, '
'tooltip: $tooltip, '
'legend: $legend, '
'toolbox: $toolbox, '
'grid: $grid, '
'series: $series, '
'type: $type, '
'xAxis: $xAxis, '
'yAxis: $yAxis, '
'maxValueY: $maxValueY, '
'maxY: $maxY'
')';
}
