decodeChartTitle<D> static method

ChartTitle<D>? decodeChartTitle<D>(dynamic map, { bool validate = true, })

Decodes the object from a Map-like dynamic structure. This expects the JSON format to be of the following structure:

{
  "behaviorPosition": <BehaviorPosition>,
  "innerPadding": <int>,
  "layoutMinSize": <int>,
  "layoutPreferredSize": <int>,
  "maxWidthStrategy": <MaxWidthStrategy>,
  "outerPadding": <int>,
  "subTitle": <String>,
  "subTitleStyleSpec": <TextStyleSpec>,
  "text": <String>,
  "titleDirection": <ChartTitleDirection>,
  "titleOutsideJustification": <TitleOutsideJustification>,
  "titlePadding": <int>,
  "titleStyleSpec": <TextStyleSpec>
}

      value: map,
      validate: validate,

      behaviorPosition: decodeBehaviorPosition(
