decodeLinePointHighlighter<D> static method
Decodes the object from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"dashPattern": <List<int>>,
"defaultRadiusPx": <double>,
"drawFollowLinesAcrossChart": <bool>,
"radiusPaddingPx": <double>,
"selectionModelType": <SelectionModelType>,
"showHorizontalFollowLine": <LinePointHighlighterFollowLineType>,
"showVerticalFollowLine": <LinePointHighlighterFollowLineType>,
"symbolRenderer": <SymbolRenderer>
}
